+# Changelog
+
+All notable changes to this project are documented in this file.
+
+## [1.3.0] - 2026-07-20
+
+### Added
+
+- Multi-organization Azure DevOps configuration with organization-specific PATs, default projects, and an optional `organization` argument across MCP tools. The existing single-organization configuration remains supported.
+- Wiki tools for listing wikis and reading wiki pages.
+- Work item attachment upload, download, and metadata tools.
+- Work item discussion retrieval and pull request thread comments.
+- Pull request thread creation, status updates, and pull request updates.
+- Work item relation linking.
+- `ActivatedDate` and `ClosedDate` fields in work item responses.
+
+### Fixed
+
+- Work item parent IDs are now derived from the Azure DevOps `Hierarchy-Reverse` relation.
+
+### Removed
+
+- Flow analytics, WIP analysis, bottleneck, workload, and aging report tools introduced in v1.2.0.
+
+### Upgrade notes
+
+- Existing single-organization installations do not require configuration changes.
+- To use more than one organization, configure `AzureDevOps:DefaultOrganization` and `AzureDevOps:Organizations`, or the equivalent environment variables documented in `.env.example`.
+- Clients that used the removed analytics tools must migrate those workflows before upgrading.
