For a list of files included in the packages see https://github.com/cefsharp/CefSharp/wiki/Output-files-description-table-%28Redistribution%29
• Chromium has removed support for Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2008. See https://chrome.googleblog.com/2015/11/updates-to-chrome-platform-support.html
• Starting in June 2019 Google will block logins from CEF based browsers to Google Services, this includes Gmail, Drive, Docs, see https://security.googleblog.com/2019/04/better-protection-against-man-in-middle.html?m=1 for further discussion see https://groups.google.com/a/chromium.org/d/msg/embedder-dev/STyM5ZNTHMM/POj1v_cqBgAJ
• Due to licensing issues default builds do not support proprietary codecs like H264/AAC, sites like Netflix/Twitter/Instagram/Facebook won't play video/audio. See #1479 for more info. MP3 audio is supported, MP4 video is not.
