-## [1.4.0] - 2025-12-25
+## [0.2.0] - 2025-12-30
+
+### Added
+
+- Support for XML-based tool calling via `--tool-format xml` flag.
+- XML-specific prompts for all built-in tools (`bash`, `grep`, `read_file`, `write_file`, `search_replace`, `todo`).
+- `XMLToolFormatHandler` for robust parsing of XML tool calls and generation of XML tool results.
+- `supported_formats` field in `ModelConfig` and backend implementations to manage compatibility.
+- Dynamic tool prompt resolution in `BaseTool` allowing automatic fallback to standard prompts if XML version is missing.
+- First public release of ReVibe with all core functionality
+
+### Changed
+
+- TUI Visual & Functional Enhancements:
+  - Added `redact_xml_tool_calls(text)` utility in `revibe/core/utils.py` to remove raw `<tool_call>...<tool_call>` blocks from assistant output stream
+  - Refactored `StreamingMessageBase` in `revibe/cli/textual_ui/widgets/messages.py` to track `_displayed_content` for smart UI updates
+  - Enhanced premium tool summaries in chat history:
+    * Grep now shows as `Grep (pattern)` instead of `grep: 'pattern'`
+    * Bash now shows as `Bash (command)` instead of raw command string
+    * Read File now shows as `Read (filename)` with cleaner summary
+    * Write File now shows as `Write (filename)`
+    * Search & Replace now shows as `Patch (filename)`
+  - Applied redaction logic to `ReasoningMessage` in `revibe/cli/textual_ui/widgets/messages.py` to hide raw XML in reasoning blocks
+
+### Fixed
+
+- Case-sensitivity issue when specifying tool format via CLI.
+- Type errors in backends when implementing `BackendLike` protocol (added missing `supported_formats`).
+- Typo in `XMLToolFormatHandler` name property.

+# TUI Visual & Functional Enhancements
+
+I have implemented several key changes to the TUI to improve the visual experience and support the new XML-based tool calling mode.
+
+## 1. XML Tool Call Redaction
+- **File**: `revibe/core/utils.py`
+- **Change**: Added `redact_xml_tool_calls(text)` utility.
+- **Purpose**: This function detects and removes raw `<tool_call>...</tool_call>` blocks from the assistant's output stream. It supports partially written tags, ensuring that raw XML never "flickers" on screen during streaming.
+
+## 2. Streaming UI Refresh
+- **File**: `revibe/cli/textual_ui/widgets/messages.py`
+- **Change**: Refactored `StreamingMessageBase` to track `_displayed_content`.
+- **Purpose**: Allows the UI to smart-update only when visible content changes. If a tool call block starts in the stream, the UI detects the decrease in "visible" characters (due to redaction) and resets the stream to prevent showing fragments of XML.
+
+## 3. Premium Tool Summaries
+I updated the display logic for all built-in tools to provide a cleaner, more premium aesthetic in the chat history:
+
+- **Grep**: Now shows as `Grep (pattern)` instead of `grep: 'pattern'`.
+- **Bash**: Now shows as `Bash (command)` instead of a raw command string.
+- **Read File**: Now shows as `Read (filename)` with a cleaner summary.
+- **Write File**: Now shows as `Write (filename)`.
+- **Search & Replace**: Now shows as `Patch (filename)`.
+
+## 4. Reasoning Integration
+- **File**: `revibe/cli/textual_ui/widgets/messages.py`
+- **Change**: Applied the same redaction logic to `ReasoningMessage`.
+- **Purpose**: Ensures that even if the model starts thinking about tool calls in its reasoning block, the raw tags remain hidden from the user.
