+### What Changed in v5.6 (2026-06-20)
+
+| Change | Impact |
+|--------|--------|
+| **qtbase GLES3/KHR header fix** | Added fallback to ensure `KHR/khrplatform.h` exists in sysroot for Qt's OpenGL/EGL includes. Fixes build failure where qopengl.h cannot find KHR/khrplatform.h. |
+| **KWin added to build** | Uncommented `kwin = {}` in `redbear-full.toml`, added to `PRECOOK_PKGS`. Fixed qtdeclarative `-DQT_FEATURE_qml_profiler=OFF` to unblock KWin's cmake. |
+| **KF6 packages unblocked** | Updated 12 blocked KF6 recipes to match cached sources. All 48 KF6 packages now build. |
+| **D-Bus daemon socket binding fixed** | Added explicit `--address=unix:path=/run/dbus/system_bus_socket` to dbus-daemon args. Added `before = ["13_redbear-sessiond.service"]` for strict ordering. Fixes sessiond "failed to read from socket" errors. |
+| **Mesa virgl verified wired** | All 6 Mesa patches are properly wired. `virtio_gpu_dri.so` builds (17.4MB). Runtime validation pending QEMU test. |
