- OS-19143: @brightsign/compositor functions pause(), resume() only work for graphics generated by BrightSign objects such as, roTextWidget, roImageWidget etc. roHtmlWidget graphics cannot be paused() and resumed()
roHtmlWidget Migration Tips
The Chromium 87 to 120 upgrade is designed to be as transparent as possible for roHtmlWidget users. However, you may need to make the following changes to your application code:
- New trusted_iframes_enabled flag in security params: To enhance security iframes are now denied access to BrightScript-JavaScript objects and Node.js by default. The following example shows how to set this new parameter while keeping code backwards compatible:
- BrightScript-JavaScript Objects resources: Several of the BrightScript objects have a Close method that will shut down the instance to prevent it from further consuming resources. If this method is not called, garbage collection determines when the instance will be destroyed. From this release onwards all BrightScript-JavaScript Object have a Close method and you should modify your application code to call this. The following example shows how to call the new Close method in BSMessagePort and keep backwards compatiblity.
- The timing of roHtmlWidget initialization has changed in Chromium 120 compared to Chromium 87. This affects how SetUserData and MapFilesFromAssetPool behave when using constructor properties.
9.1.52 Beta (June 18, 2025)
This Beta release supports all BrightSign Series 3, 4, 5, 6 (XS156) and LGUV5N players. This release enables partners to evaluate this version in their production environments and specific use cases prior to a General Availability (GA) release.
New Features
- OS-16282, OS-17497, OS-17652, OS-18041, OS-18420, OS-18421: roHtmlWidget now uses Chromium 120:
- Series 5 players can switch back to Chromium87 by setting the html > widget_type registry value to chromium87.
- roHtmlWidget cannot be switched back to Chromium87 on Series 3 and 4 players.
- OS-18181: (General) Added a new registry value, html > disable-http-cache 1, that allows customers to completely disable the Chromium HTTP cache to reduce the number of files created on SD card.
- OS-17871: (LS5, HS5) Enabled the NPU
- OS-19173: (General) Added a new registry setting, html > web_inspector_port, that allows the web inspector port to be changed from the default value of 2999

Proposed Feature Changes
The behaviour of the audio volume curve on Series 4 players will be altered in the General Availability release to align with that currently used on Series 5 and 6 players.
- Series 4 has previously implemented a linear curve whereas Series 5/6 implement a logarithmic curve, so there was a mismatch between the series
- On Series 4, the default behavior will be the same logarithmic curve as Series 5 and is defined in a registry setting.
- The JavaScript audiooutput and BrightScript roAudioOutput APIs will support functions to switch between the default logarithmic curve and legacy linear curve, for backwards compatibility.
Known Issues (Temporary)
The following known issues will be addressed before the General Availability release:
- OS-14352: Specifying custom fonts for browser using AddFont API and fonts roHtmlWidget constructor parameter is no longer supported. Use HTML webfonts as a substitute. This feature is only supported in BrightAuthor Classic (not BrightAuthor:connected).
- OS-17651: Mouse scroll is not supported on roHtmlWidget on Series 4
- OS-18297: Tearing on HD5 and XD5 when GPU rendering is used with Chromium to play certain lower resolution videos with BrightSign video player.
- OS-19145: Sharing the BrightSign player output over WebRTC is not supported
- OS-19358: (LGUV5N) Audio has been enabled, and defaults to 100% of maximum (normal BrightSign behavior). Media with audio will play at high volume since there is currently no volume control on the display.
Known Issues (Permanent)
There is no plan for the following known issues to be addressed. They are either deprecated or deleted features:
- OS-17098: mpcdi is not supported
- OS-19143: @brightsign/compositor functions pause(), resume() only work for graphics generated by BrightSign objects such as, roTextWidget, roImageWidget etc. roHtmlWidget graphics cannot be paused() and resumed()
Supervisor (2.0.23), DWS (1.43.0), and Autorun (0.0.88) Updates (OS-18337, OS-18381, OS-18788, OS-18848)
- BCN-17505: (BrightSign Built-in) The default autorun can now use flash as the default storage
Chromium 120
- OS-18548: Fixed the implementation of focus tracking so window focus works correctly when a second window is displayed
- OS-19093: Fixed CVE-2025-0395
Chromium 120 Known Issues
- BSSecureStore is being replaced by @brightsign/securestore. Please review the documentation for the migration example. This is a permanent, not temporary, issue.
