Change Log

For a complete list of changes see the 83.3.x Milestone

Notes

• CefSharp requires Visual C++ 2015. See #1983 for details. You can bin deploy the VC++ dependencies, read the FAQ for more details.
• 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 require OAuth authentication when accessing web services that rely only Google Account Data, 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.
• Anyone new to CefSharp should read the General Usage Guide
• This project uses GitLink for better debugging, you can step directly into much of the project source directly from Visual Studio see #1680 for details on how to enable GitLink
• WPF now has touch support which is enabled by default. Support for Stylus is not enabled by default, see #228 (comment) for further details
• CEF now supports Print Preview see #2332 for details on how to enable it (WinForms only)
• CEF now supports range requests for ResourceHandlers see https://bitbucket.org/chromiumembedded/cef/issues/2836/cefstreamreader-createforfile for details.
• WPF the rendering implementation in CEF has been rewritten see https://bitbucket.org/chromiumembedded/cef/issues/2733/viz-osr-might-be-causing-some-graphic for details. This should overall improve performance.

Known Issues

• WPF there is some visible tearing/glitches on resize #3114
• WinForms when running on Windows 10 Anniversary pressing certain key combinations freezes the browser see #1822 The issue has been reported upstream, there are workarounds listed in #1822

• Background colour cannot be override for popups see https://bitbucket.org/chromiumembedded/cef/issues/2482/background_color-cannot-be-overridden-for
• WPF Browser goes blank if used in combination with TabControl see #2779

• See https://github.com/cefsharp/CefSharp/issues?q=is%3Aissue+is%3Aopen+label%3Aknown-issue for other known issues

Breaking Changes

Notes

• CefSharp requires Visual C++ 2015. See #1983 for details. You can bin deploy the VC++ dependencies, read the FAQ for more.
• Starting in June 2019 Google will require OAuth authentication when accessing web services that rely only Google Account Data, 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
• 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
• MP3 audio is now supported by default.
• 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.
• Anyone new to CefSharp should read the General Usage Guide
• This project uses GitLink for better debugging, see #1680
• WPF now has a VirtualKeyboardRequested event that can be used to display a virtual keyboard see #1736 for full details
• WPF now has experimental touch support, it's not enabled by default, see #228 (comment) for further details
• BrowserSettings life cycle has changed, if created by CefSharp the object will be disposed automatically, if user created then it will be up to the user Disposed or Garbage collected. See for full details #2643
• Legacy Javascript binding registered JavaScript objects no longer get lost when navigating to another domain.

Known Issues

• WinForms when running on Windows 10 Anniversary pressing certain key combinations freezes the browser see #1822 The issue has been reported upstream, there are workarounds listed in #1822
• Browser goes blank if used in combination with WPF TabControl see #2779
• Setting CefSettings.RootCachePath has no effect (https://bitbucket.org/chromiumembedded/cef/issues/2740/cefsettings-root_cache_path-is-not). The fix was applied to the 3770 branch, there is no official build available that includes this fix. No known workaround, you might need to skip this version and wait for the next major release.
• WPF dropdown(select element) closes after mouse wheel https://bitbucket.org/chromiumembedded/cef/issues/2547/drop-down-box-select-element-closes-after
• A list of the Network Service related bugs that I'm aware of is at #2743 (comment) (there are possibly more issues that I'm not aware of).
• LoadHtml/RegisterResourceHandler displays empty page #2872
• CefSettings.IgnoreCertificateErrors no longer works, use the ignore-certificate-errors command line arg as a workaround.
• Intermittent crash on shutdown is caused by the new Network Service, see https://bitbucket.org/chromiumembedded/cef/issues/2703/crash-when-closing-if to workaround you can disable the Network Service example at #2743 (comment)
• See https://github.com/cefsharp/CefSharp/issues?q=is%3Aissue+is%3Aopen+label%3Aknown-issue for other known issues

Breaking Changes

• For Network Service API changes see #2743
