For OBS versions 27.1.3 and newer, on (an updated) Windows 10 2004 (released 2020-05-27) or later.

• Adds translations for French, Chinese, German, Russian, Spanish and Chinese Traditional (Taiwan).
• Rewrite of the core capture code to C++ (with WIL/WRL) to use a MMCSS registered MF queue to improve stability under load.
• Fixes error handling for when the ActivateAudioInterfaceAsync call fails on outdated Windows.
• Removes capture helper to simplify code and match the support that will eventually land in OBS - this means that with two Application Audio Capture Sources pointed at the same window only one will capture audio. Use Add Existing to have the same source in two scenes.

You may have to re-add your pre-existing sources or manually uninstall before installing if updating from a previous version.
