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.
