 All notable changes to the "format-switcher" extension will be documented in this file.
 
-Check [Keep a Changelog](http://keepachangelog.com/) for recommendations on how to structure this file.
+Format follows [Keep a Changelog](https://keepachangelog.com/).
 
 ## [Unreleased]
 
-- Initial release
+## [0.3.0] - 2026-03-08
+
+### Added
+
+- **Two new formats**: `lower words` (space-separated lowercase) and `UPPER WORDS` (space-separated uppercase).
+- **Cycle command** (`extension.formatSwitcher.cycleCase`) — automatically detects the current format and advances to the next in the cycle: `camelCase → snake_case → kebab-case → CONSTANT_CASE → Train-Case → lower words → UPPER WORDS → camelCase`.
+- **Keyboard shortcut** `Ctrl+Shift+F` mapped to the cycle command (only active when editor has a selection, avoiding conflicts with "Find in Files").
+- **Multi-cursor support** — all active selections are converted simultaneously.
+- `LICENSE` file (MIT).
+- GitHub Actions CI pipeline (lint → build → test).
+
+### Changed
+
+- Replaced `lodash` runtime dependency (~4.7 MB) with native TypeScript implementations, reducing the packaged extension size by over 95%.
+- Case conversion logic extracted to a standalone `caseConverters` module for testability.
+- Comprehensive unit test suite (40+ assertions) replacing the placeholder boilerplate.
+
+### Fixed
+
+- Context menu submenu now only appears when text is actually selected (`when: editorHasSelection`).
+- Internal `CaseType` literal `'Constant case'` corrected to `'upperSnakeCase'` for consistency.
+
+## [0.2.0] - 2024-01-01
+
+### Added
+
+- Initial release with five case conversions: `camelCase`, `snake_case`, `CONSTANT_CASE`, `kebab-case`, `Train-Case`.
+- Right-click context menu submenu "Change case".
+- `lodash` used internally for text segmentation.

 ## Features
 
-`Format Switcher` is a simple extension that allows you to change the formatting of selected text in the editor. The extension adds a new menu item to the context menu.
+`Format Switcher` is a VS Code extension that transforms selected text between seven naming-convention formats via the right-click context menu or a keyboard shortcut.
 
-The extension supports the following cases:
+Supported formats:
 
-```plaintext
-CamelCase
+```
+camelCase
 snake_case
 CONSTANT_CASE
 kebab-case
 Train-Case
+lower words
+UPPER WORDS
+```
+
+- **Multi-cursor support** — all active selections are converted simultaneously.
+- **Context menu** only appears when text is selected (no more silent no-ops).
+
+## Installation
+
+**From the Marketplace:**
+
+1. Open VS Code
+2. Press `Ctrl+P` and run: `ext install EdFerVIIIA.format-switcher`
+3. Or search **"Format Switcher"** in the Extensions view (`Ctrl+Shift+X`)
+
+**From a VSIX file:**
+
+```
+code --install-extension format-switcher-<version>.vsix
 ```
 
 ## Usage
 
-![Format Switcher](./images/ExtExample.gif)
+Select any text, right-click, and choose **Change case** → pick the desired format.
 
-## Requirements
+## Keyboard Shortcut
 
-This extension uses the following libraries
+Press **`Ctrl+Shift+F`** with text selected to **cycle** through formats in order:
 
-```json
-"lodash": "^4.17.21"
 ```
+camelCase → snake_case → kebab-case → CONSTANT_CASE → Train-Case → lower words → UPPER WORDS → camelCase → …
+```
+
+The shortcut only activates when the cursor is inside the editor with a selection, so it does not conflict with the default "Find in Files" shortcut. You can customise the keybinding any time via **File → Preferences → Keyboard Shortcuts**.
