v10-rc2

Changes since rc1

• Fixes #916

v10-rc1

Release schedule:

rc1 released on: Oct 29, 2022
Final release: Nov 14, 2022

Build changes:

• picom now needs libEGL to build

Notable changes:

• experimental-backends is now the default. Everything should keep working, except the --glx-fshader-win option. The old window shader support has been replaced by --window-shader-fd. This new shader support has a different interface, so you have to adapt your existing shaders. (#875)
• legacy-backends option has been added so you can go back to the old backends, which will eventually be removed.
• picom.desktop is installed to /etc/xdg/autostart/. picom should autostart now. (#791)
• Shadows and blur now match the shape of the window. This includes windows using the XShape extension, and windows with rounded corners. (#882)
  Example:
  
• New option: --transparent-clipping-exclude, for excluding windows that doesn't play well with transparent-clipping, such as screenshot tool windows. (#663 #738)
• New backend: egl. It should behave exactly the same as the glx backend. Give it a try! (#878)

Other changes:

• --help messages have been refactored, leading to clearer code. (#877)
• picom tries to detect and act on GPU resets. But because of the limitation of the X server, this ended up not being very useful.

Deprecation:

• Raw string pattern in conditions are deprecated. It never worked because of libconfig handles escape sequences in string.

Changelog

@tryone144 has officially joined as a collaborator, hooray! 🎉

Notable changes:

• New blur method for the experimental backends: dual-kawase #382
• Support for rounding the corners of windows #551 #558 #614 #761 #716
• Usability of picom-trans is improved. #634 (Thanks to @subnut)
• It's now possible to match against all values of a window property in rules. Some window properties have multiple values (e.g. _NEW_WM_STATE), using _NEW_WM_STATE[*] in a match will succeed if any of the values match. #550
• Fix darkening of window edges when using blur.
• Some long deprecated options are removed. If picom doesn't start after update please check its console output. #768

New options:

• New wintype options:
  • blur-background. enable/disable background blurring per window type.
  • clip-shadow-above. prevent shadow from being rendered on top of certain window types. #656
• shadow-color: specify color in 1 option rather than separately in 3.
• corner-radius, rounded-corners-exclude: for rounded corner support.
