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.

Changelog

Here are some of the notable changes since v7

New features

• You can now use the time variable in window shaders to get a timestamp. An example usage is to create animated effects, e.g. https://streamable.com/e0x7r (Thanks to @resloved #330)
• --max-brightness, which allows you to dim windows that are too bright. When enabled, all windows' average brightness will be clamped to the set value. (Thanks to @Jauler #247)
• Automatic configuration file reloading after it's changed.

Improvments

• A lot of the artifacts seen with blur and use-damage enabled are fixed.
• _NET_WM_BYPASS_COMPOSITOR property are now handled. (Related to i3/i3lock#204)
• Completely transparent windows won't have a blurred background anymore. (Thanks to @tryone144 #364)
• Improved fullscreen window detection. Now EWMH is used to detect fullscreen windows as well. You can turn it off with --no-ewmh-fullscreen (Thanks to @tatokis #187)
• Various improvments to the inverter.sh script (Thanks to @Paradigm0001 #362, and @quequotion #281)

Configuration changes

• wintype notify has been renamed to notification to match the EWMH names. (Old name still works)

Behavior changes

• picom no longer sets the opacity property on windows based on opacity rules. This is to fix the problem where picom "forgets" it set the opacity property after, e.g., window manager restarts. #134

Build changes

• libxdg-basedir is no longer a dependency (Thanks to @dylanaraps #322)

Fixes

• Fixed wrong client window detection after i3wm restarts #299
• Fixed wallpaper disappearing after screen resolution changes.
• Fixed crashing when a really big window is created with shadow
• Fixed --frame-opacity with the experimental backends
• --blur-* command line options are now handled properly (Thanks to @tryone144)
• Various build fixes (Thanks to @jenav #241, @jbeich)
• Various memory leakage fixes (Thanks to @liskin #236)
• Various documentation fixes and improvments (Thanks to @avivace, @tryone144, @davidschlachter, @liskin, @verfriemelt-dot-org)
• Various other crash, assertion failure fixes

v7.5

Only change since v7.4 is the rename from compton to picom, which is
backported from the next branch.

As a user, you don't need to update to this version.

As a distro packager, you should only package this version if you want
to adopt "picom" as the package name.

v7.4

• Fix several memory leaks, thanks to @liskin (#236)

v7.3

• Build changes:
  • Vendor test.h so people building from the release tarballs doesn't
    have to clone that repository with git (#224)
