Version 8.2.0 - 2019-11-29

1. REST API behaviour updated for initial Access Controls upon object creation:
   • When new objects are CREATED they are made accessible to the operator (the user who authenticated) AND all groups the operator is a member of (as listed in the access tab for the user who authenticated).
   • If new objects should not become members of the groups the operator is a member of, the query string?autoGrantGroupAccessControls=false can be added to the request.
   • When existing objects are UPDATED the access controls are NOT modified.

Version 8.1.0 - 2019-11-17

1. Screen status notifications
   • New advanced group option to send offline screen notifications to users via email.
   • When enabled, hourly checks will be performed on all screens in the group.
   • One or more offline screens in the group will trigger a notification email to be sent to users that have direct access to the group (i.e. in group access tab).
   • Screen status checked every 1 hour for notifications.
   • Emails will be sent from screenstatus.net via SendGrid.
2. Updated all dependencies to latest versions.
3. Updated data access layer to support running without starting additional services.
4. Added simple API for fetching screenshots and logs from devices. (unpublished)

Version 8.0.3 - 2019-11-12

1. External process for removing compressed chunks updated to support safe removal during transition from regular compressed chunks to cold compressed chunks.

Version 8.0.2 - 2019-11-11

1. The remove expired sequence option now only removes items with an end date that is before the current time. (Previously items with no end date were incorrectly removed.)
2. REST API updated to not overwrite objects created date.
3. Fixed problem querying user action reports that cross from previous year to current year.

Version 8.0.1 - 2019-10-24

1. Updated smart display pacing logic.
   • When play count above pacing, play probability divided by 1.5.
   • When play count below pacing, play probability multiplied by 1.5.
   • When decreasing - less than 0.01 is rounded to 0
   • When increasing - less than 0.01 is rounded to 0.01, maximum 1.0
2. Added a new dialog to initialise starting condition when a target play count is set.
3. Suppressed alert from JsException when removing the typeahead from the DOM after touch event.
4. Improved sequence, group and user selection select/typeahead component to display more information.
5. Moved extend visibility option to be next to select/typeahead component it affects.

Version 8.0.0 - 2019-10-13

1. Servers maintain play counts for each item with reporting enabled.
2. Play counts synchronised with item metadata periodically (10 minutes).
3. To maintain counter increments during asynchronous data replication with eventual consistency, one counter for each server (shard) is stored. Replication uses idempotent maximums to merge shards.
4. Sequence item metadata only updated after changes are detected.
5. Added support for Targets and smart display pacing.
   • Added option to define a target play count for an item.
   • System dynamically changes probability of displaying item to reach target by end date. (smart display pacing)
   • Reporting tab replaced with Campaign tab.
   • Start and send dates moved to Campaign tab.
   • Added progress bars to show play counts and current pacing.
6. Consolidated some library item options to Defaults tab to clarify that these options are not directly linked to a stack item when added to a sequence.
7. Added support for bounce authentication. By referring a user to a special address they can be automatically signed in. For example: /auth?email=me@mydomain.com&password=mypassword. This will create a session, add a cookie and redirect to the admin interface. This must be performed over a secure connection and has security implications (not recommended).

Version 7.6.9 - 2019-10-05

1. Fixed problem selecting a screen/sequence for the playback simulator when over 10,000 screens/sequences.
2. Inner sequences containing inner sequences introduced a premature MaxDurationExceededException when items referring to the inner sequences did not have durations exceeding the total duration of items referring to the inner sequences at the deeper level. The result was inner sequence rotation applied incorrectly and valid items skipped in the deeply nested inner sequence. If deeply nested inner sequences are in use, please update players to android-player-21.2 and android-exoplayer-8.2. Alternatively, items referring to inner sequences can be configured to have a duration longer than the total duration of the inner sequence items to prevent the issue occurring.
3. Static random value reset after an item is displayed if data reused.
4. Fixed problem detecting and propagating sequence frame updates to players.
5. Updated gwtbootstrap3 to version 1.0.0 and gwtbootstrap3-extras to version 1.0.0.

Version 7.6.8 - 2019-09-30

1. Fixed problem with anonymous registration that resulted in a JavaScript error displayed in admin interface.

Version 7.6.7 - 2019-09-25

1. REST API updated to ensure itemId is automatically allocated and added to items when report=true is set.

Version 7.6.6 - 2019-09-13

1. Fixed problem where dragging a modal window breaks scrolling vertically.

Version 7.6.5 - 2019-09-01

1. Added exception propagation when accessing a remote data warehouse.
2. Exceptions from data warehouse summary report API returned in response. These were previously hidden by sending CSV header line too soon followed by no records.
3. Better support for string representation of date/time in stack items for when items must be displayed according to the screens timezone and not the admin user.

Version 7.6.4 - 2019-08-25

1. Fixed API import problem when HTTP server returns data with chunked encoding and no defined content length.
2. Updated YouTube importer to download 1080p video stream and identify incompatible streams with use_cipher_signature=true set. Video format preference order 37, 22, 18.
3. Added support libraries for PDF generation ready for PDF summary reports in next release.

Version 7.6.3 - 2019-08-13

1. Updated re-encoding progress to be based on input file size.
2. Increased max duration for re-encoding to 1 hour.
3. Changed visual style of long errors in item details.

Version 7.6.2 - 2019-08-10

1. User action records created for all objects updated as part of a multiple selection / bulk operation.
2. Increased bulk screen instant update threshold from 10 to 50.
3. A3 now counts number of potential advertisers viewing an advertising group.
4. Screen response optimisation to remove A3 items where adSuitable == false. A3 assigned items will not be preemptively downloaded by devices until adSuitable == true.

Version 7.6.1 - 2019-08-06

1. Added support for custom update packages. Admin interface option added to commands list when loaderVersion >= 15.0.
2. Added additional validation logic to REST API for User, Group and ServerConfig objects.
3. Fixed sequence not found error when saving a screen with uncleared sequence typeahead from previous save.
4. A3 interface updated to support setting adSuitable and adEnabled via toggle switches.
5. Fixed problem relaying UDP between servers when administrator and screen in different geographic regions.

Version 7.6.0 - 2019-07-14

1. Updated all .jar dependencies.
2. Added custom URL handling for selfad.co.
3. SendGrid integration for sending emails.
4. Automatic Advert Assignment (A3) updated:
   • Video advert support added.
   • Slot duration restrictions applied to videos.
   • Activation emails.
   • Support for enabling / disabling adverts using authorised link in activation email.
   • Advert pools. Uploaded adverts create additional slots. Designed to be used as an inner sequence, where a single advert is shown each loop of the main sequence. This allows displaying more adverts than slots in the main sequence.
5. New sequence type for Advert pools. This sequence type grants A3 permission to add items.
6. Assigning a customId that is already used in a sequence no longer merges items to use the same itemIdfor reporting. This means a customId functions more like a tag where reporting on a customId can return multiple unique items. Logic for RSS sequences differs because the RSS GUID is used as a unique identifier and is used to prevent creating different reporting items when RSS feeds update.
7. Added support for additionalReadOnlyData in cloud configuration to mark custom data fields as read-only. For example additionalReadOnlyData=LicenceID in active cloud configuration would prevent users changing the LicenceID field in item data.

Version 7.5.3 - 2019-06-28

1. Composite item label updated if display item updated by selecting a new item from the library.

Version 7.5.2 - 2019-06-25

1. Groups in group selection list sorted alphabetically.
2. Group name hidden in group selection list unless there are duplicate labels.
3. Added checkbox option to permanently disable showing the Too many items warning.
4. Fixed issue where copied library items, sequences and clouds were not automatically added to groups the operator is in.
5. Fixed issue where adding data to a custom launch intent threw an umbrella exception.

Version 7.5.1 - 2019-06-24

1. Fixed umbrella exception that appeared after clicking the multiple selection button.
2. Improved handling of InvalidEmailException and InvalidNameException.

Version 7.5.0 - 2019-06-22

1. Admin interface object data UI editor only built on demand when data tab clicked. Significant speed up for editing objects with many data fields such as users and screens.
2. Fixed issue where 2nd edit of object fields was not saved unless set in data tab.
3. A3 updated to show count of screens that will show new advert on map.
4. Fixed usedBy field which was incorrectly maintained in stacked sequences.
5. Fixed sequence not found error when saving a screen with sequence typeahead unpopulated.
6. Fixed issue where help tips were not removed after clicking OK.

Version 7.4.9 - 2019-06-19

1. Updated HTTP header parsing for overriding media processing in upload handler. Options are:
   • X-MediaProcessing=noprocess - Disable all media processing
   • X-MediaProcessing=norescaleimages - Disable generation of additional rescaled images
   • X-MediaProcessing=novideoimages - Disable generation of preview images for videos
2. Updated datasource redirection logic to correctly pass referrer datasource options.
3. Server ignores reports sent from devices if report=false set in screen data.

Version 7.4.8 - 2019-06-03

1. When Require secure authentication (HTTPS) enabled, existing insecure sessions over HTTP will be blocked

6. Blocked uploads with filename ending with .exe and .js.

Version 7.4.6 - 2019-05-28

1. Added support to change Email to Username as configured in cloud config by userIdentifier=username

Version 7.4.5 - 2019-05-25

1. Add null BLOB uploader. This is to support additional addresses for already populated blobstores.
2. Added additional server healthcheck for loader communications.
3. Ensured healthcheck fails immediately after shutdown starts.
4. Reduced shutdown time when no datasources are active.
5. Added 10 most recent healthcheck events to healthcheck API response.

Version 7.4.4 - 2019-05-15

1. Added support for launching custom Android Intents. (requires android-player-18.2+ or android-exoplayer-5.2+)

Version 7.4.3 - 2019-04-30

2. The created date used as default client-side sort for groups and cloud configs.
3. Fixed problem where column customisation lost if refresh clicked before preferences saved to server.
4. Added sequenceIdOverride to enable quick override of a screens sequenceId without losing configured setting of sequenceId. This will be used to show emergency items and to temporarily disable non-paying customers.

Version 7.4.1 - 2019-04-14

1. Increased security by strict policy on incorrect passwords to combat brute force password attacks.
   • 5 incorrect passwords and the server will ignore subsequent password attempts.
   • After 10 minutes of zero attempts, user or source IP can try again.
2. Increased security by comparison with 100,000 most common passwords.
   • New passwords can not match password in the common passwords list.
   • Users with existing passwords in the list will receive a warning when signing in.
3. Fixed problem showing web page zips in item info icons and details
4. Added support for maxBitrate to configure threshold for displaying bitrate warning.

Version 7.4.0 - 2019-04-06

1. The item erase button no longer requires the user erase feature to be enabled. The erase button is enabled for all item types except screens which are maintained for billing and statistics purposes. The reason for this change is to reduce the name/email collisions caused by existing clouds, groups and users in the system and also prevent items accessible to groups no longer maintained.
2. New button to increase the maximum items loaded in a single query.
3. Reduced the default maximum items loaded to 1000 to improve performance for users managing large numbers of items.
4. Moved the warning when maximum items exceeded to point at new button.

11. Admin interface performance optimisations:
    • A configured maxResults aborts server-side object loading except when filtering.
    • Server-side filtering only performed when search query provided.
    • Sorting only performed client-side
    • Improved pagination responsiveness by deferred thumbnail rendering.
12. Dropped support for Internet Explorer 8 and 9 (removed from GWT permutations)

Version 7.3.6 - 2019-03-28

1. Group totals now recursively count items in sub groups.
2. Group summary option shown for all groups (not exclusive to groups containing screens)
3. Fixed error displaying options drop down for groups when items column was hidden.
4. Fixed error saving sequence for screen after switching from extended visibility back to normal.
5. Setting max two factor age in cloud config to zero will force users with 2nd factor enabled to provide code every time they sign in.
6. Two factor authentication made available to all users and no longer requires twoFactor=true in cloud.
7. Basic authentication is not accepted if two factor authentication enabled.
8. 3rd party sign in (oauth) is not accepted if two factor authentication enabled. (We may support hybrid later).
9. Improved admin interface error reporting.

5. Improved GPS movement map for displaying screen locations for infrequent display records.
6. Added showAddItemOption=false to hide the add item option from sequences.
7. Extended showEditOption=false to disable stack item double clicking and dragging.

Version 7.3.3 - 2019-03-01

1. Fixed problem displaying screen status report.

Version 7.3.2 - 2019-02-27

1. Library performance dramatically improved by caching item information icons.
2. Changed search box behaviour to search local cached data. To search beyond max results limit it is necessary to press refresh or return.

2. Mouse hover over map marker lists all screens in location of the marker.
3. Clicking a marker performs a search for all screen in location.
4. Added support for comma separated list of IDs to search to return multiple items in single search.

Version 7.2.6 - 2019-02-07

1. Changed scale for charts so single digit values are not repeated.
2. Fixed rare race condition when saving custom columns in user data for display report and display summary.
3. Fixed group recursion, which could fail if there is no search criteria in view state.

Version 7.2.5 - 2019-02-01

1. Fixed error in User and Group summary report for active screen count.
2. Removed APK link from sign in page for all clouds. Google marked one domain as "unsafe" and it is assumed this is the reason.
3. Added option to disable group recursion. By default, group recursion automatically lists items contained in nested groups. Adding groupRecursion=false to user data will disable group recursion and limit the visible depth to the first layer of access controls. I.e. Items the user has direct access to and items contained within groups the user have direct access to.

Version 7.2.4 - 2019-01-30

1. Fixed screen status history report CSV where date/time ranges were shifted back by 1 record.
2. Abstracted clickable items in tables to use bootstrap badges for simplicity and efficiency.

3. Added multiple selection options to enable and disable user features.
4. Added sort functions to items listed in the edit group dialog.
5. Changed REST filter operation to return false if the condition throws an error. This means a filter will not cause an API call be aborted if an object is missing a data field.
6. Added support for fetching user and group summaries using the REST API (not public yet - used by invoicing).
7. Fixed rare race condition when saving custom columns in user data. Column saving will now only occur after no changes to columns are made for 5 seconds.

Version 7.2.0 - 2019-01-13

1. Added new parameters to REST API to support searching users by email, groups by group name and server configs by name.
2. Added type field to REST API responses to simplify object deserialization using Jackson annotations.

11. Added ability to filter by parent group to user and group summary report.

Version 7.1.6 - 2019-01-05

1. Changes to dynamic resources inside a composite item were not being detected by modification checks. This is now fixed.

Version 7.1.5 - 2018-12-13

1. Group dialog only loads items in group when items tab is clicked.
2. Fixed issue with building location conditions where regions with no address are clicked.
3. Preview fixed for composite items within a sequence within a sequence frame.

Version 7.1.4 - 2018-12-07

1. Updating numeric values in composite item editor now changes the preview correctly.
2. Drawing tool for location builder map now reset when component reused.
3. REST API changed so that POST returns 201 (created) instead of 200.
4. REST API changed so that system administrators can not perform POST, PUT or DELETE. System administrators have too much power and this closes a possible attack vector.
5. Added new Quick Data API endpoint /api/group-screen-data/{group-name} to support updating data of all screens in a group with a single API call.
6. Added additional column to library to display both active resource size and total resource size.

5. Added options showRssPreviewOption showRssPreviewOption showExpireOptions showFindSequenceOption showCopyOption showRemoveOptionshowEditOption to support further customisation of the admin interface.
6. If home tab is disabled for a user and library and sequence tabs are not, the sequence tab will be shown after sign in.

Version 7.1.2 - 2018-11-21

1. Content builder definitions are now loaded after clicking "build content using another service" rather than with the admin interface configuration. This is to support loading and refreshing remote 3rd party content builder specifications on demand.
2. Added new boolean field, serverImport, to content builder definition to support content builders that return a URL that should be displayed in a WebView rather than importing binary data server side. This is for live HTML5 content.
3. Updated number formatters to avoid bugs with locales that use a comma for the decimal separator.

Version 7.1.1 - 2018-11-13

1. Added new panel to home tab to display recent user actions.

Version 6.6.3 - 2018-09-11

1. Querying by a specific group now includes results for groups within the group (nested grouping). This operation is used when filtering by groups in admin interface and REST API.
2. Added new option to filter REST API results. The parameter filter can take a predicate which will be applied to a list of objects. For example &filter=modifiedMillis>1536839304634. Please note, the filter value must be URL encoded.
3. Display report records sent to server can now be queued or disabled to facilitate data warehouse management. Disabling data warehouse writes causes player to retry later and suppresses regular player commms for updates.

Version 6.6.2 - 2018-09-10

1. Data warehouse V1 fully disabled.
2. Data warehouse V1 removed from codebase.

Version 6.6.1 - 2018-09-06

6. API summary reports now use data warehouse V2.
7. API report requests now ignore backend parameter and use data warehouse V2 regardless.
8. Data warehouse V1 no longer used for reads. (writing will be disabled in next release)
9. Updated GeoLite2 database and library. (Used for resolving IP to location when no GPS data)
10. Full clean and rebuild with latest build tools.

Version 6.5.1 - 2018-08-23

1. Modified data warehouse splicing logic to reduce memory footprint.
   • Queries aggregating a small number of screens/items (under 50) spliced by time.
2. Server side filtering now uses visible columns for non custom search parameters.

Version 6.4.12 - 2018-08-20

1. Added upload and import limit of 4GB. This limitation is needed because:
   • Android secondary partition, SD cards and USB mass storage using FAT can not store files larger than 4GB.
   • Google Cloud Storage does not support uploading over 5GB in a single transfer.
2. Fixed exception when filtering report by both a user and a group simultaneously.

Version 6.4.11 - 2018-08-16

1. Fixed minor layout issue showing access control tab on small mobile devices.
2. Disabled option in admin interface to query Warehouse V1. Does not affect reporting API, but users are encouraged to move to backend=warehouseV2 ASAP.

Version 6.4.10 - 2018-08-13

1. Disabling the reporting feature showReports=false now also prevents using the API for reporting.
2. Restricted column width used for groups and user labels in access control tab of dialogs.

Version 6.4.9 - 2018-08-09

1. Invalid screen IDs and item IDs sent in display reports from devices now ignored. File corruption most likely cause, especially when devices are not shut down correctly.
2. Fixed NPE when handling emails sent without a from address in the headers.
3. Default display report backend when not specified is now warehouseV2.
4. Added logging to track use of deprecated display report backend.
5. New option added to remove dialog to support reuse of an email address, group name or cloud config name. New option simply appends a timestamp to email / name so that it is no longer in use and can be reclaimed.
6. Fixed search box that sometimes returned the wrong results when search delayed.
7. Added condition length limit of 8K. Exceeding limit will show error in admin interface. New players will evaluate these conditions to false.

Version 6.4.8 - 2018-07-24

1. Fixed problem with data editor ignoring updates to data after it is removed. One known consequence was default duration (60 minutes) lost when selecting a new inner sequence for an item.
2. Clicking anywhere on the video playback preview will now unmute audio. Please note: videos start muted so autoplay will function (recent Google Chrome policy change breaks autoplay with audio).
3. Unified the item duration logic. durationMillis not set if it matches a resource duration or the default (10 seconds).
4. Fixed number formatting problem when resource or item millisecond less than 100.

Version 6.4.7 - 2018-07-19

1. Instant updates are now quicker when updating screen data in admin interface.
2. Instant updates are no longer attempted if the server has not had recent UDP confirmation from DS Loader.
3. Instant updates using the remote trigger API for screen groups now skips screens without UDP connectivity.

2. Added Device start column to screens table. Uses hardwareBootMillis.
3. Added detection of multiple devices sharing the same MAC by monitoring hardwareBootMillis for significant jumps backwards in time. When a duplicate is detected, hardwareBootMillisDebug=duplicate is added to screen data.
4. Changed default time formatter to include seconds in tables.
5. Fixed problem displaying last UDP comms time in screen table.

Version 6.4.5 - 2018-07-11

1. Fixed over-caching of player API response which sometimes prevented automatic updating of dynamic content such as weather images.
2. Server side searching by EntityInfo (as used by sequences tab) is now consistent with client side searching.
3. Warning for multiple recent starts not shown if screen is offline.
4. Weather translation for Swedish updated.

Version 6.4.4 - 2018-07-03

1. Changed groupId filter behaviour in data warehouse v2 backend to match v1.
2. Admin interface for display reports now changes group label to clarify if report is filtered by group of screens, sequences or library items.
3. Fixed data duplication problem when changing data names in the data tab.
4. Replaced sign in prompt when a permission error occurs while masquerading with an error message. Signing in as another user in the middle of a masquerade session does not work as expected so functionality has been removed.
5. Label of composite item updated if a new library item is selected.
6. Updated legacy content builders to use UTF8. Unfortunately many APIs we use only support English terms though.
7. Added workaround to enable auto-playing videos in HTML5 preview (recent versions of Chrome prevent this). The workaround is to mute the video by default.

Version 6.4.3 - 2018-06-28

1. Fixed problem searching for meta data by email, group name or cloud config name. This caused problems manually adding new access controls.
2. Improved validation of display report records sent from players.

Version 6.4.2 - 2018-06-21

1. Fixed issue where reporting data referencing a missing screen would cause report generation to fail.
2. Fixed NPE when searching for an ID that does not exist.

Version 6.4.1 - 2018-06-19

1. Changed behaviour of data tabs.
   • Data tabs now highlight changes made to data with yellow stars.
   • All updates are visible and modifications made in the data tab take precedence.
   • The data tab can be used for advanced modifications and provide understanding of how various options relate to stored data.
2. Added options to set scrolling text, NFC URL and Beacon URL in screen edit dialog.
3. Fixed problem generating reports by Item ID and Library Item ID.

Version 6.3.2 - 2018-06-15

1. Searching by text that looks like an ID now performs fast ID fetch rather than full search.
2. Manual text entry of indirectly accessible users and groups within access tab of items is now case insensitive.
3. Fixed issue where the incorrect access controls were applied to new items when a sign in performed while masquerading.
4. Added additional retry logic for uploading blobs to S3 and GCS.

Version 6.3.1 - 2018-06-06

1. Larger number of concurrent uploads and downloads supported. Fixed issue where ThreadPoolExecutor did not apply the expected level of concurrency.

Version 6.3.0 - 2018-05-25

1. Removed legacy (MySQL) database connectivity.
2. Data warehouse V2 used exclusively for user actions (audit trail), blob upload log, collected data and screen status history.
3. Data warehouse V2 now the default for display reports, data warehouse V1 will remain active for a limited time.
4. Updated style of library items and stack items to support more info icons and removed shadows which were degrading performance.
5. Selecting None from suggestion boxes removes the selection.
6. Any errors updating dynamic content now shown in item details.

Version 6.2.1 - 2018-05-21

1. Options to jump to display reports and display summary now correctly pre-populate search criteria.
2. Suggestion boxes for sequences, screens and groups correctly loaded when jumping between tabs.

Version 6.2.0 - 2018-05-16

1. Added sequence playback simulator.
   1. Creates a report with information about items that will display based on configurable data such as date/time.
   2. Displays a summary of duration and storage requirements.
2. Additional error responses added for invalid API requests.
3. Worked around a bug in DS Loader that could cause app restart immediately after booting. Note, new DS Loader recommended.
4. Added GPS movement map link to display report when screen GPS data collected with collectGps=true.
5. Added suggestion boxes when specify screen, sequence or group for reports.

Version 6.1.0 - 2018-05-12

1. Newly added library items starred. Star removed after they are added to a sequence.
2. Display report CSV now always generated on server to avoid browser limitations.
3. Sanitised input to oauth2callbacks eliminating possible cross site scripting.

Version 6.0.2 - 2018-05-08

1. Fixed bug where longitude was displayed in latitude column.
2. Reordered columns so latitude comes first.
3. Fixed location heatmap for display reports.
4. Display report CSV and heatmap now open in new windows/tabs.

Version 6.0.1 - 2018-05-04

1. If there are multiple thumbnail candidates in one item, the most recent is used. (Based onmodifiedMillis in resource data).
2. New header X-MediaProcessing=noprocess added to upload requests disables automatic media processing. Note: This advanced option requires metadata to be sent in the data of the pending resource, for example image width and height.
3. Custom data added to a pending resource is copied to final resource after completion if it does not exist.
4. The invalid Content-Type text/txt is now fixed by using supplied file extension.

Version 6.0.0 - 2018-05-03

1. Data warehouse version 2 introduced with support for custom record types:
   • Standard display records.
   • Display records containing longitude and latitude. Designed for moving screens. (collectGps=truerequired in screen data)
   • Collected data. (Email addresses, phone numbers, text, URLs etc as configured in events)
   • User actions (audit trail).
   • Blob upload records. Added blobstore field to identify uploads to multiple blobstores.
   • Screen status history records. Changes to structure to avoid need for aggregation.
2. After a transitional period, data warehouse version 2 will replace the legacy (mySQL) database and version 1 data warehouse implementation.
3. Updated all reports ready for data warehouse version 2:
   • Backend selection options. (while we transition)
   • Configurable columns for display summary and display reports.
   • Columns for custom ID and library items referenced from records.
   • Columns for GPS longitude and latitude. Note: When GPS is not known at specific point in time, values are gray and taken from current screen data.
   • Support for filtering by screens in a group in addition to other criteria.
   • CSV built client-side using the selected columns.
   • Link to show GPS locations as a heat map.
4. Screen status history now uses data warehouse version 2:
   • New implementation improves screen summary chart generation speed by 10X.
   • Processor intensive aggregation no longer necessary.
   • Fixed problem where aggregated records were incorrectly offset by 10 minutes. (Note historical records will show this discrepancy)
   • CSV download option (and API response) returns a more understandable format with start and end times for each time period.
5. Large report queries that exceed number of records that can be displayed in admin interface interrupted to avoid wasting resources. Default limit currently set at 100,000 records.
6. Record queues are now persisted to local storage, so an unexpected server failure will not result in losing queued records in RAM.
7. Atomic record queue re-processing to cope with communication failures between servers.
8. Data warehouse version 2 uses LZ4 compression for archiving instead of GZIP to significantly speed up record processing.
9. New records and report communications between servers chunked and compressed using LZ4.
10. Display summaries spanning thousands of screens and larger periods now possible using dynamic criteria splicing by screen and time.
11. Re-encoded videos uploaded to custom blobstores if defined in active cloud configuration.
12. Fixed problem where pending resources are removed prematurely if createdMillis not defined in data.
13. Blob upload stall detection now waits 5 minutes before aborting. This helps avoid aborting early if blob uploads are queued.
14. Added new pie segment for number of screens downloading to screen status on home tab.
15. Admin interface now built with GWT 2.8.2.

Version 5.6.6 - 2018-03-25

1. CSV updated to remove gpsLatitude and gpsLongitude because they broke badly written partner integrations.
2. Reporting API updated to support use of the parameter fields to select what fields to include in the report.

Version 5.6.5 - 2018-03-24

1. Fixed error caused by clicking a sequence item if the create sequence feature for the user was disabled.
2. Fixed problem shift clicking a range in a table when no previous item selected.
3. Increased maximum label length before trimming in tables to 60 characters.
4. Fixed caching issue where endDateTime in items generated invalid Last-Modified in screen response.
5. Support for receiving display records containing GPS location. (not stored yet)
6. Display report CSV updated to contain gpsLatitude and gpsLongitude. Note these will currently be set to the last known location. In a future version, the current location will be stored in display records when collectGps=true set in screen data to support moving screens.

Version 5.6.4 - 2018-03-02

1. Fixed problem with redirected imports not uploading data to custom blobstores defined in active cloud config.
2. All exceptions related to blobstore uploads are now logged.
3. Added more information about blobstore uploads to server health check.
4. Minutely healthcheck fails if there are failures to upload to one or more blobstores.

8. Items built using a template or widget no longer inherit created date of source.
9. Controls added to videos shown in preview.

Version 5.6.3 - 2018-02-27

1. Replaced play and stop icons in screen status history report with exclamation mark, warning icons. A play icon did not emphasise that there could be a problem with devices crashing/rebooting.
2. Re-enabled body text selection. This previously caused unwanted highlighting when dragging, but modern browsers now handle this correctly and highlighting text elsewhere is useful.
3. Removed itemId and sequenceId columns from collected data report. This is in preparation of future changes to optimise how we collect, store and process GPS data in this report. It will be necessary to join display report and collected data report to reconstruct the columns in the future.
4. Group and email suggestion boxes now move exact matches by name/email to top of list of results if there are more results than what are going to be displayed.

Version 5.6.2 - 2018-02-22

1. Added button to collected data report to show collected GPS data as a Google heatmap.
2. Fixed screen API response for stack items with floating start and end dates used by A3.

1. Fixed problem with alert dialog that could cause "Maximum call stack size exceeded" error to be displayed.

Version 5.6.0 - 2018-02-18

1. Data replication information now includes replication points of sources of a source. This information is used to avoid unnecessary duplicated replication when replicating from multiple sources. It also means that replication can maintain speed in the event of a very low transfer rate in one direction between two servers.
2. Replication rate between geographically distant servers reduced to once every 5 seconds.

Version 5.5.0 - 2018-02-16

1. Display report and summary report now include the Item ID column.
2. Display report and summary report show a warning if screens have not sent all reporting data up to the end date specified.
3. Display summary report includes total showings for all items/screens.
4. Display summary report now reset when clicking a display summary option from an item or screen.
5. Removed finish masquerading option because in many cases it failed to close the browser window and caused confusion.
6. Fixed problem where browser session timeout before server session timeout could cause stack overflow error.
7. Simplified how object metadata is transfered between frontend and backend. EntityInfo objects are now generic and only contain required data.
8. Player API response no longer includes expired items.
9. A3 introduction and basic guide added.

Version 5.4.6 - 2018-02-08

1. Fixed problem with date parsing that prevented updating the month in date text fields.

Version 5.4.5 - 2018-02-07

1. Fixed problem displaying summaries when over 1,677,721 (including duplicates) records were processed. This only affected the view in the admin interface and not reporting done via the API or download CSV button.
2. Added a debug button to the reporting info dialog so we can see more details about the query to solve potential problems with date ranges.

Version 5.4.4 - 2018-02-06

1. When masquerading as a user with a custom cloud config, the config is also sent in upload metadata. This means uploads will also be transferred to any custom blobstores set in the custom config.
2. Added active transfer details to item info pop-ups.
3. Fixed screen table error triggered by sequences with no label.
4. End date entry components set to 1 millisecond before selected date to help with adjacent time ranges.
5. Timeout for server to server warehouse report data transfer increased.
6. Display report and summary de-duplication optimised for faster results.

Version 5.4.3 - 2018-01-31

1. Playback reporting on items referring to inner sequences is no longer supported.
   • Error displayed when saving item with playback reporting enabled that refers to inner sequence.
   • When saving a sequence in admin interface, playback reporting option on existing items referring to inner sequences is automatically disabled.
   • Screen communications now removes reporting option on items referring to inner sequences.
2. Display reports and summaries are now processed to remove invalid and duplicate records. An invalid record has an unexpected time, a missing itemId or screenId. A duplicate record has the same display time, itemId and screenId as a previous record.
3. Increased the max display report size shown in admin interface from 10,000 to 100,000 records.
4. Automated Advert Assignment (A3) Prototype 1
   • Added item scheduling table.
   • Added advert upload functionality.
   • Schedule advert button adds item to sequence stacks with defined schedule.

Version 5.4.2 - 2018-01-25

1. The seqeunceId field in legacy database for display reports and collected data reports is no longer used. The itemId is now used to look up the ItemInfo metadata which includes the sequenceId. This results in more compact storage in the legacy database and more consistent results when comparing data with the new data warehouse. Note, if an itemId is duplicated across multiple sequences then the wrong sequence may be referenced. This regresses change made in 5.3.0.
2. Removed unused field sequenceId from StackItem.
3. Any sequenceId sent from players in display reports is ignored and new players will not send it.
4. Default reporting backend when not specified in API request is now the data warehouse.

Version 5.4.1 - 2018-01-19

1. Aggregation options hidden from display report where they should not be shown.

Version 5.4.0 - 2018-01-18

1. DataSources referencing remote objects now use SHA256 of the URL as the ID irrespective of the length. The URL is now stored within data.url. This should resolve replication issues with URLs over 512 characters and previous issues with 1024 character URLs.
2. 6,946 active DataSources migrated to new schema.
3. Updated cleanup script to remove unused and invalid DataSources.
4. Various updates to support Raspberry Pi player migration.

Version 5.3.4 - 2018-01-16

1. Added frontend support for aggregating display summary report by screen and item-screen.
2. Fixed problem updating preview of inner sequence when inner sequence contains no items.
3. Limited the number of files that can be dropped into browser at once to 10.
4. Fixed issue with WTM that resulted in blocking proxies such as squid.

Version 5.3.3 - 2018-01-15

1. Fixed exception caused by selecting random in the advanced condition builder.
2. Added backend support for aggregating display summary report by screen and item-screen.
3. Screens offline for over 28 days no longer included in the hom screen status pie chart.
4. Fixed problem saving the 2nd factor age in cloud configuration
5. Added support for a default sequence to be applied to new screens. This is set by adding sequenceId in cloud config screen defaults. Note: desiredPlayer will also need to be set to start playback.

Version 5.3.2 - 2018-01-07

1. Changed default reporting backend to the new data warehouse.

Version 5.3.2 - 2018-01-07

1. Changed default reporting backend to the new data warehouse.
2. Updated date selection widgets to reset seconds field to zero.
3. Updated condition builder to allow manual text condition editing after building.
4. Editing a composite item now correctly displays the composite editing options.
5. The library is shown in several places. Adding, removing or updating library items anywhere will now encourage a refresh everywhere.
6. Stale content refreshes when switching between tabs based on last refresh time not tab change time.
7. Item paste operation duplicates all additional data associated with the copied item.
8. Added 1 second delay to thum.io for rendering thumbnails. Helps when HTML component runs JavaScript.
9. Set thum.io to use Europe-1 server when rendering Zipped web pages as US-East-1 appears to be blocked.
10. Added option to use time zone of screen rather than time zone of user for stack item start and end date evaluation. Option currently unavailable for non admin users until players updated. Required and used by A3.
11. A3 can now display the available time slots and reserve them (basic scheduling).
12. Importing media using URLs longer than 1024 bytes is now possible. When a URL is longer than 512 bytes the SHA 256 hash of the URL is used as the primary key for the DataSource object. The full URL is stored in a new data field fullId and automatically reapplied when the DataSource is saved or accessed via DataSourceDao. This fixes the MongoDB 1024 byte key length limitation.

Version 5.3.1 - 2017-12-31

1. Updated the display tab for items to improve access to various upload, import and building options.
2. Added new option to build HTML content from template.
3. HTML template and HTML widget library now populated by templateGroupIds and widgetGroupIds set in data of cloud config or user config. This facilitates having multiple groups of templates and widgets for different users.
4. HTML template option only shown when user has add composite widget feature enabled. (This may change in next release)
5. Screen status history report screen label now performs screen search when clicked.
6. Fixed issue where very fast uploads failed to refresh item list and remove progress bars.
7. Added default start time and end time for report downloads. When not specified, last 24 hours are returned.
8. Preview option for Zipped web pages added.
9. BlobExtractServlet at /blob-extract/ downloads blob and serves unzipped files for previewing zipped web pages.
10. Integration with thum.io for rendering admin interface thumbnails of web pages and zipped web pages.
11. Added support for resume delay over 1000 seconds.

Version 5.3.0 - 2017-12-09

1. Changed behaviour of sorting by ON column. Screens grouped by on/off and then label rather than lastLoaderCommsMillis. This provides a more consistent view where screens do not move around when refreshing.
2. Changed default sort order for the screen status history report to use the updated ON column sorting.
3. Removed option to edit screens from screen status history reports. Reports should not be able to perform updates.
4. Changed default max duration for items referring to inner sequences to 1 hour - Most users want inner sequences to play more than 10 seconds and inner sequence rotation is often misunderstood, so long default is better.
5. Fixed group selection problem for reports where group was reset unexpectedly.
6. Fixed problem where group selection was still visible when an ID was used in reporting criteria. Group filtering is not currently supported when reporting by ID.
7. Removed unnecessary initial load of screen status history before screens shown in report.
8. Changed reporting API to use stored sequenceId for legacy reports instead of sequenceId in item metadata. Note, sequence may be wrong in data warehouse if same ID used for multiple sequence items in different sequences.
9. Subtitle .vtt files modified when uploaded to prevent potential crash. 00:00:00.000 replaced with 00:00:00.001 to avoid divide by zero exception in subtitle renderer on Minix devices.
10. Removed disabled items from screen response JSON. This reduces unnecessary data transfer to screens.
11. Background update of datasources not queued if already in queue.
12. Optimised SequenceLinker to flatten deep inner sequence structure into fewer database queries.
13. Admin interface thumbnail renderer flattens deep inner sequence structure to speed up composition.
14. Search behaviour changed when spaces are used.
    • Search string split into multiple search terms by spaces.
    • Items that contain all search terms are shown.
15. Added new field usedBy to sequences for performing dependency lookups.
    • SequenceTool replaced with SequenceLinker with functionality for updating usedBy field.
    • Base sequences usedBy is populated by upper sequences referring to them.
    • Inner sequences usedBy is populated by outer sequences referring to them.
    • Sequences in usedBy checked and removed when sequence refreshed.
    • Automated Advert Assignment (A3) uses new field to discover all screens connected to a sequence and that will display an advert slot.
    • Remove dialog uses new field to notify user when an outer sequence or upper sequence will be affected by removing a sequence.
16. Automated Advert Assignment (A3)
    • Please note: A3 is still in development and for alpha testing only.
    • Split slot settings dialog into multiple tabs.
    • Added option to enable A3 to slot settings.
    • Added new user interface module for A3. Currently located at /ad/group-name.
    • A3 lists advert slots in sequences within the specified group.
    • A3 shows map of locations that will display advert slot.
    • A3 shows list of time periods available to show advert.

Version 5.2.3 - 2017-11-20

1. Removed options button from screen status history report.
2. Added additional check to ensure file upload data sent matches value set in Content-Length header.

7. Updated screen status history to work better with reporting on thousands of screens.
8. Added screen option to view screen status history.

Version 5.2.2 - 2017-11-15

1. A colour can be assigned to library items and sequence items.
2. Advanced erase feature made available. Unlike remove, items will be erased from all users and groups.
3. When importing a URL that is already cached, a new cloud config will force an update. This ensures custom blobstores are updated.

Version 5.2.1 - 2017-11-07

1. Stalled and slow transfers to blobstores now detected and aborted.
2. Excessive concurrent blobstore uploads detected and aborted.
3. Blob uploader refactored and untangled from media processor.
4. Upload error feedback to UI improved.
5. Additional performance logging added to media processing.
6. Fixed issue where current user was re-added to access tab if all users and groups were removed from the access tab.
7. Range selection using shift fixed for non default sort order.
