+## [1.0.46] - 2025-05-27
+
+### Fixed
+
+- Fixed issue where GitLab issues and milestones with null descriptions would cause JSON-RPC errors
+  - Changed `description` field to be nullable with default empty string in schemas
+  - This allows proper handling of GitLab issues/milestones without descriptions
+  - See: [PR #53](https://github.com/zereight/gitlab-mcp/pull/53), [Issue #51](https://github.com/zereight/gitlab-mcp/issues/51)
+
+---
+
+## [1.0.45] - 2025-05-24
+
+### Added
+
+- 🔄 **Pipeline Management Tools**: Added GitLab pipeline status monitoring and management functionality
+  - `list_pipelines`: List project pipelines with various filtering options
+  - `get_pipeline`: Get detailed information about a specific pipeline
+  - `list_pipeline_jobs`: List all jobs in a specific pipeline
+  - `get_pipeline_job`: Get detailed information about a specific pipeline job
+  - `get_pipeline_job_output`: Get execution logs/output from pipeline jobs
+- 📊 Pipeline status summary and analysis support
+  - Example: "How many of the last N pipelines are successful?"
+  - Example: "Can you make a summary of the output in the last pipeline?"
+- See: [PR #52](https://github.com/zereight/gitlab-mcp/pull/52)
+
+---
+
+## [1.0.42] - 2025-05-22
+
+### Added
+
+- Added support for creating and updating issue notes (comments) in GitLab.
+- You can now add or edit comments on issues.
+- See: [PR #47](https://github.com/zereight/gitlab-mcp/pull/47)

 ## [1.0.38] - 2025-05-17

-### Fixed
+### 1.0.40 (2025-05-21)
 
-- Added `expanded` property to `start` and `end` in `GitLabDiscussionNoteSchema`  
+- Added support for listing discussions (comments/notes) on GitLab issues.
-  Now you can expand or collapse more information at the start and end of discussion notes.  
+  - Example: You can now easily fetch all conversations (comments) attached to an issue via the API.
-  Example: In code review, you can choose to show or hide specific parts of the discussion.  
+  - Related PR: [#44](https://github.com/zereight/gitlab-mcp/pull/44)
-  (See: [PR #40](https://github.com/zereight/gitlab-mcp/pull/40))
