+
+A short wait, finally concluded: 0.50.0 is here.
+
+This update brings a lot of new stuff and fixes, here are just a few notable ones.
+
+## Breaking changes
+
+- Legacy renderer has been dropped. Hyprland now requires at least GLES 3.0 to function
+- `explicit_sync` related settings in `render:` have been nuked. Explicit sync is always used by default.
+- render-ahead-of-time settings have been nuked. They weren't used anymore.
+
+## Notable new stuff
+
+### New render scheduling
+
+There's a new option under render, `render:new_render_scheduling`. It will dynamically switch to triple buffering when your
+system cannot keep up. This can drastically improve FPS on underpowered devices, while coming at no performance or latency cost
+when the system is doing alright.
+
+Please note this option is disabled by default and experimental, as we've had some select setups struggle with it. Hopefully by 0.51
+we can iron out those issues and have it on by default.
+
+### No screen share
+
+There's a new rule, `noscreenshare`, which will black out any window with it in screensharing, for privacy.
+
+### Internal test framework
+
+We've finally (after a few months) managed to finalize the test framework. Each commit is now automatically tested
+with a range of automatic tests, to hopefully catch regressions earlier. It can't test _everything_, but it can test
+a bunch of things, and we hope to get more and more tests there as time goes on.
+
+### Other
+
+Other new stuff include amongst others:
+- New `monitorv2` syntax for monitor configs that are less cluttered
+- tons of small optimizations (thanks Tom!)
+- new `ext_workspace_v1` support
+- multi-gpu support for `drm_lease`
+- CM fixes for mpv crashes
+- new `unbind = all` option for the config
+- new `cm_auto_hdr` for automatic HDR
+- new `group:` selector for windowrules
+- new permission management for keyboards
+- and more...
+
+
+### Fixes
+
+Tons of fixes, including:
+- fixes for some `hyprpm` and hyprland crashes.
+- fixed some minor blur artifacts on popups
+- snap now respects outer gaps
+- hyprpm will now print out what's wrong instead of just dying when trying to add a new repo without an update first
+- some minor xwayland fixes
+- ANR dialog will now disappear if the app dies
+- hyprland will no longer crash if a monitor's driver rejects all available modes
+- fixed some missing window fade out cases (esp. around special workspaces)
+- fixed some crashes around switching cursor themes on the fly
+- a few textures are now loaded dynamically to save VRAM when not needed
+- screencopy selection boxes are now calculated properly for transformed monitors
+- workspaces behind screen locks are no longer rendered for privacy reasons (this can be disabled in the config)
