 # Changelog
 
+## 0.5.0
+
+The newly added GPUs require [WhateverXe Graphics 0.2.0](https://github.com/b00t0x/WhateverXe-Graphics/releases). Its rendering fixes also benefit previously supported GPUs; updating both components is recommended.
+
+### Added
+
+- Add Alder Lake-S graphics acceleration and HDMI/DisplayPort output, including compatible USB-C wiring and up to three displays.
+- Accept Tiger Lake-H45, Alder Lake-HX and Raptor Lake-S/HX using shared support. These configurations still need hardware testing.
+- Use firmware information to configure more display layouts automatically.
+
+### Fixed
+
+- Avoid some startup panics caused by display hardware not being ready.
+- Restore Safari graphics-driver access regardless of where macOS installs Safari updates.
+- [WhateverXe Graphics 0.2.0](https://github.com/b00t0x/WhateverXe-Graphics/releases) fixes observed Chrome drawing failures and rendering errors on smaller integrated GPUs.
+
+DisplayPort/USB-C reconnection can still freeze the computer. See the [README](https://github.com/b00t0x/WhateverXe#tested-features-and-known-issues) for tested configurations and other known issues.
+
 ## 0.4.0

 ### Known issues and limits
 
 - Some image-conversion operations can crash the application.
 - Reconnecting a monitor to a dedicated DisplayPort connector can leave the
-  screen black or freeze the computer. USB-C DisplayPort Alt Mode passed the
-  reconnection checks above.
+  screen black or freeze the computer. USB-C DisplayPort Alt Mode reconnection
+  can also freeze the computer; this has been reproduced on both Big Sur and
+  Tahoe.
 - Safari video playback may occasionally drop frames.
 - Up to three displays can be used simultaneously; a fourth display will not
   receive an image.
+- DisplayPort output or reconnection can be slow on Alder Lake-S.
+- Some connector layouts, Thunderbolt-managed outputs and panel backlight
+  methods are not supported. See [display limits](docs/device-selection.md#display-limits).
+- FairPlay-protected playback is not supported.
 - Full system sleep/wake and resolutions above those listed above are unverified.
   USB-C display output currently prevents part of the display hardware from
   entering a low-power state.
 
 ## Roadmap
