+## [2.3.0] - 2024-11-13
+
+This minor release includes some improvements and adds official Unreal Engine `5.5` Fab support.
+
+### Added
+
+- Added `USGAndroidPermissions` to the `SenseGloveAndroid` module, enhancing the plugin's permission request process on Android. Now, a pop-up prompts the user to grant permissions, preventing silent crashes when permissions haven't been granted beforehand.
+- Added Unreal Engine `5.5` Fab support.
+
+### Fixed
+
+- Fix UE `5.5` deprecation warnings inside `USGVirtualHandComponent`.
+- Additional minor fixes and improvements that may not be listed here.
+
+## [2.2.2] - 2024-11-08
+
+This patch release addresses a few issues with both glove and hand-tracking.
+
+### Fixed
+
+- Fixed a chain of critical bugs that gets triggered due to `GloveConnectivityCheckInterval` getting passed as seconds to the engine rather than milliseconds. Thus, the default or any large value for `GloveConnectivityCheckInterval` causes noticeable long delays between glove-connectivity-check intervals and consequently renders the hand-tracking state invalid in certain situations when the `bFallbackToHandTrackingIfNoGloveDetected` option is false.
+
 ## [2.2.1] - 2024-10-23
 
 This patch release focuses exclusively on updates to the documentation.
