 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [2.1.3] - 2024-10-11
+
+### Added
+
+- Added initial support for the upcoming Unreal Engine `5.5` release. Please note that, while the plugin is functional, a few adjustments are still required to address deprecation warnings. Specifically, the `FXRMotionControllerData` struct needs to be replaced with the newly introduced `FXRMotionControllerState` and `FXRHandTrackingState` structs, along with adjustments to adhere to the new hand-tracking API changes.
+- Added support for Epic Native Toolchain `v23`.
+
+### Fixed
+
+- Fix a bug inside `USGVirtualHandComponent::PostEditChangeProperty()` where the get member name check happens against the wrong class and member names.
+- Additional minor fixes and improvements that may not be listed here.
+
+### Changed
+
+- The SenseGlove libraries have been updated to `v2.105.0-02a2e508`.
+
+## [2.1.2] - 2024-09-02
+
+This is a bugfix release that addresses a few non-critical issues and documentation fixes.
+
+### Fixed
+
+- Fix a bug where the hands are always visible even when `bVisibleWhenHandDataUnavailable` is disabled.
+- Fix a bug where the `HandVisibilityChangedEvent` event is not triggered on the virtual hand component visibility changes.
+- Fix the wrong script name for `USGHMDTrackerKismetLibrary`.
+- Fix the wrong script name for `USGXRTrackerKismetLibrary `.
+- Fix `LogPython: Warning: 'SGHMDTrackerKismetLibrary' and 'SGXRTrackerKismetLibrary' have the same name (SenseGloveHeadMountDisplayKismetLibrary) when exposed to Python. Rename one of them using 'ScriptName' meta-data` when packaging the game.
+- Fix the non-existent default hand-mesh warnings polluting the logs when packaging the game.
+- Expanded the clickable area on the handbook index page revision buttons.
+- Minor documentation fixes.
+
+## [2.1.1] - 2024-08-18
+
+This is a bugfix release with no actual plugin code changes, mostly addressing issues in the documentation and third-party dependencies caused by source control merge conflicts.
+
+### Fixed
+
+- Fix the messed up changelog file caused by cherry-picking merge conflicts between the dev branch and the master branch.
+- Fix a bug that causes a handbook revision mismatch when deploying the handbook from the dev branch.
+- Fix a bug where `SG_GIT_IS_SHALLOW_CLONE` while building the handbook is always set to `yes` even if it's not a shadow clone because `SG_DOT_GIT_SHALLOW_FILE` evaluates to an empty string when the `.git/shallow` file does not exist.
+- Fix some documentation typos.
+
+### Removed
+
+- Removed Android NDK r25 armv7 and x86 dependencies brought back by mistake while merging v2.1.0 from the dev branch to the master branch.
+
 ## [2.1.0] - 2024-08-16
 
 This is a minor release focusing mainly on bringing OpenXR-compatible hand tracking support (`XR_EXT_hand_tracking`) and Head-mounted Display automatic detection for adjusting wrist tracker offsets automatically at runtime.
@@ -127,6 +173,14 @@ This is a minor release focusing mainly on bringing OpenXR-compatible hand track
 - The `UXRDeviceVisualizationComponent` provided by Unreal Engine is used in the SGPawn class as ControllerVisualizerLeft and ControllerVisualizerRight for implementing the wrist tracking hardware visualization feature. However, it is not compatible with the new OpenXR system in certain scenarios. For instance, when the motion controllers serve as wrist tracking hardware since the SenseGlove plugin is now introduced to the engine as an `OpenXRHandTracking` system, it causes the UXRDeviceVisualizationComponent to visualize the wrist tracking hardware at coordinates (0.0f, 0.0f, 0.0f) instead of their actual location and rotation in the world. This happens because the component incorrectly registers them as inactive, possibly because it's assumed hand tracking and motion controllers cannot be in use at the same time. Currently, we use this feature solely for debugging, and we have an alternative in the form of wrist-tracking debug gizmos, which can be toggled on or off via the settings system. In future releases, we might remove this feature due to its incompatibility, unless we find a solution to make the `UXRDeviceVisualizationComponent` work with the new system. Alternatively, we may develop our own version of the `UXRDeviceVisualizationComponent`.
 - Although the SenseGlove OpenXR implementation is fully compatible with the `IOpenXRHMD` interface and the `FOpenXRHMD` `XRTrackingSystem`, it is not compatible with the `FOculusXRHMD` backend provided by the Meta XR plugin. The same issue likely applies to the VIVE OpenXR plugin. So, if these plugins are enabled in your project, the SenseGlove OpenXR will not function as intended, effectively breaking the plugin's functionality. It seems these plugins are necessary in order to make the fallback to the hand-tracking feature work on Android. While we may add support and compatibility with Meta XR and VIVE OpenXR plugins in the future, for the time being, if your project requires these plugins, we advise continuing with the `v2.0.x` release of the SenseGlove Unreal Engine plugin until this issue is addressed.
 
+## [2.0.8] - 2024-07-15

+This is a bugfix release that contains a somewhat important bugfix backported from the next release of the plugin as documented below.
