v127.3.50

August 22, 2024, CEF 127.3.5+g114ea2a+chromium-127.0.6533.120 / Chromium 127.0.6533.120

• ⚠️ This is the last version to support the Alloy Bootstrap (upstream) (#4835). Those using the Chrome Runtime previously will need to set CefSharpSettings.RuntimeStyle = CefRuntimeStyle.Chrome;
• 🛑 Switching from Alloy Bootstrap to Chrome bootstrap appears to ignore cookies from the previous version as the encryption keys are likely different. You can switch back to the Alloy bootstrap if required via cefSettings.ChromeRuntime = false; #4835
• CEF now supports the Chromium process singleton, this brings with it changes to how CachePath/RootCachePath are accessed from multiple processes. See #4668 for more details
• ⚠️ Microsoft Visual C++ 2019 Redistributable is required. A minimum of VC++ 2019 is required, higher versions are backwards compatible. For those upgrading from a previous version which only required VC++ 2015 minimum see #3636 for some guidance.

• Due to licensing issues default builds do not support proprietary codecs like H264/AAC, sites like Netflix/Twitter/Instagram/Facebook/Spotify/Apple Music won't play video/audio. See #1479 for more info. MP3 audio is supported, playing MP4 files are not supported.
