# Unreleased
## New features
* Allow `corner-radius-rules` to override `corner-radius = 0`. Previously setting corner radius to 0 globally disables rounded corners. (#1170)
* New `picom-inspect` tool, which lets you test out your picom rules. Sample output:
```
...
Checking rounded-corners-exclude:
window_type = "dock" ... not matched
window_type = "desktop" ... not matched
window_type *= "menu" ... not matched
fullscreen = 1 ... not matched
Checking opacity-rule:
_NET_WM_STATE@[0] *= "_NET_WM_STATE_HIDDEN" ... not matched
Checking corner-radius-rule:
class_g = "Alacritty" ... matched/10
Here are some rule(s) that match this window:
name = '[0.2.1] ./picom-inspect: ~/p/picom(./picom-inspect: ~/p/picom)*'
class_i = 'Alacritty'
class_g = 'Alacritty'
window_type = 'normal'
! fullscreen
border_width = 0
```
## Notable changes
* Marginally improve performance when resizing/opening/closing windows. (#1190)
* Type and format specifiers are no longer used in rules. These specifiers are what you put after the colon (':') in rules, e.g. the `:32c` in `"_GTK_FRAME_EXTENTS@:32c"`. Now this information is ignored and the property is matched regardless of format or type.
## Bug fixes
* Fix ghosting artifacts that sometimes occur when window manager is restarted (#1081)
* Fix a bug where rounded corner is disabled after making a window fullscreen and back (#1216)
## Dependency changes
* picom now uses some OpenGL 4.3 features.
* picom now optionally depends on `rtkit` at runtime to give itself realtime scheduling priority.
* `libconfig` is now a mandatory dependency.
# v11.2 (2024-Feb-13)
## Build changes
* `picom` now depends on `libepoxy` for OpenGL symbol management.
## Bug fixes
* Workaround a NVIDIA problem that causes high CPU usage after suspend/resume (#1172, #1168)
* Fix building on OpenBSD (#1189, #1188)
* Fix occasional freezes (#1040, #1145, #1166)
* Fix `corner-radius-rules` not applying sometimes (#1177)
* Fix window shader not having an effect when frame opacity is enabled (#1174)
* Fix binding root pixmap in case of depth mismatch (#984)
# v11.1 (2024-Jan-28)
## Bug fixes
* Fix missing fading on window close for some window managers. (#704)
# v11 (2024-Jan-20)
## Build changes
* Due to some caveats discovered related to setting the `CAP_SYS_NICE` capability, it is now recommended to **NOT** set this capability for picom.
## Deprecations
* Uses of `--sw-opti`, and `--respect-prop-shadow` are now hard errors.
* `-F` has been removed completely. It was deprecated before the picom fork.
# v11-rc1 (2024-Jan-14)
## Notable features
* picom now uses dithering to prevent banding. Banding is most notable when using a strong background blur. (#952)
* Frame pacing. picom uses present feedback information to schedule new frames when it makes sense to do so. This improves latency, and replaces the `glFlush` and `GL_MaxFramesAllowed=1` hacks we used to do for NVIDIA. (#968 #1156)
* Some missing features have been implemented for the EGL backend (#1004 #1007)
## Bug fixes
* Many memory/resource leak fixes thanks to @absolutelynothelix . (#977 #978 #979 #980 #982 #985 #992 #1009 #1022)
* Fix tiling of wallpaper. (#1002)
* Fix some blur artifacts (#1095)
* Fix shadow color for transparent shadows (#1124)
* Don't spam logs when another compositor is running (#1104)
* Fix rounded corners showing as black with the xrender backend (#1003)
* Fix blur with rounded windows (#950)
## Build changes
* Dependency `pcre` has been replaced by `pcre2`.
* New dependency `xcb-util`.
* `xinerama` is no longer used.
* `picom` now tries to give itself a real-time scheduling priority. ~~Please consider giving `picom` the `CAP_SYS_NICE` capability when packaging it.~~
## Deprecations
* The `kawase` blur method is removed. Note this is just an alias to the `dual_kawase` method, which is still available. (#1102)
