 - Fixed code samples, such as in the "View code" dialog, titled "Javascript" instead of "JavaScript": common programming languages and their aliases, such as `js`, now show their proper names, which can be overridden via `overrideLocalizedStrings` (`PROGRAMMING_LANGUAGE_*`), in PR [#5896](https://github.com/microsoft/BotFramework-WebChat/pull/5896), by [@OEvgeny](https://github.com/OEvgeny)
 - Fixed code not being highlighted when the programming language is not in lowercase, such as `TS`, in PR [#5896](https://github.com/microsoft/BotFramework-WebChat/pull/5896), by [@OEvgeny](https://github.com/OEvgeny)
 - Fixed GIFs in animation cards looping with no way to stop them: they now have a pause button, and do not play when the user prefers reduced motion or the card has `autostart: false`; the icons of the Copy and View code buttons are now visible in forced colors, fixes [#5734](https://github.com/microsoft/BotFramework-WebChat/issues/5734), in PR [#5897](https://github.com/microsoft/BotFramework-WebChat/pull/5897), by [@OEvgeny](https://github.com/OEvgeny)
-- Fixed the play, mute, and "more options" icons of audio players being invisible in dark high contrast themes, such as "Aquatic" on Windows, fixes [#5710](https://github.com/microsoft/BotFramework-WebChat/issues/5710), in PR [#5906](https://github.com/microsoft/BotFramework-WebChat/pull/5906), by [@OEvgeny](https://github.com/OEvgeny)
 - Fixed the "Positive" card action button having less than 4.5:1 color contrast, fixes [#5713](https://github.com/microsoft/BotFramework-WebChat/issues/5713), in PR [#5905](https://github.com/microsoft/BotFramework-WebChat/pull/5905), by [@OEvgeny](https://github.com/OEvgeny)
 - Fixed screen readers announcing a single audio, video, or animation in a card as a list item, such as "1 of 1", fixes [#5722](https://github.com/microsoft/BotFramework-WebChat/issues/5722), in PR [#5903](https://github.com/microsoft/BotFramework-WebChat/pull/5903), by [@OEvgeny](https://github.com/OEvgeny)
 - Fixed video and animation cards disappearing in production builds when the video URL is relative or invalid, in PR [#5889](https://github.com/microsoft/BotFramework-WebChat/pull/5889), by [@OEvgeny](https://github.com/OEvgeny)
