+## [Unreleased]
+
+### Fixed
+
+- Fixed update vscode types package and clean up now unused line comment types ([#26](https://github.com/yCodeTech/auto-comment-blocks/pull/26)) by @yCodeTech
+
+    VScode updated their types to include the LineComment typings and released 1.110 of @types/vscode package. So our temporary custom `LineComment` type and `LineCommentConfig` interface is now redundant.
+    - Updated @types/vscode package to 1.110.
+    - Removed the temporary `LineComment` type and `LineCommentConfig` interface, and removed the references in configuration file.
+          <!-- end -->
+
+### Changed
+
+- Refactored extension activation and performance improvements ([#29](https://github.com/yCodeTech/auto-comment-blocks/pull/29)) by @yCodeTech
+    - Refactored the `activate` function to set up the logger first, initialize extension data and configuration.
+
+    - Ensured that development environment variables are only loaded when not in production mode, i.e. in development or testing modes.
+
+    - Consolidated multiple configuration change handlers into a single handler that checks for a list of settings requiring extension reload. If any are changed, a single reload prompt is shown using the new `showReloadMessage` helper function, reducing code duplication.
+
+    - Improved performance and event handling to prevent memory leaks by properly disposing of old comment configurations.
+        <!-- end -->
+
+- Refactored configuration class ([#30](https://github.com/yCodeTech/auto-comment-blocks/pull/30)) by @yCodeTech
+    - Extracted the logic for determining the appropriate Blade or HTML comment style into a new private method `getBladeOrHtmlComments`, simplifying the public API and improving clarity. The `setBladeComments` method now only sets the configuration and no longer returns values based on an `onStart` flag (the flag was removed in favour using the new private method directly).
+
+    - Replaced repetitive code for adding custom single-line comment languages with a new private method `addCustomSingleLineLanguages`, reducing duplication and improving maintainability.
+
+    - Replaced `var` with `let` for variable declarations in several places to align with modern best practices.
+      <!-- end -->
