+## [2.5.0] - 2026-03-23
+
+### Added
+- Added `McpLoggingService` for MCP protocol-level logging — tool validation errors and internal exceptions now emit `notifications/message` to connected clients, improving visibility for MCP client UIs
+- Added `logback.xml` to the `current` module routing all logs away from stdout — fixes MCP spec compliance violation where log output corrupted the JSON-RPC stream for stdio transport clients (Fixes #84)
+
+### Fixed
+- Fixed stdout pollution breaking stdio transport clients — Logback previously fell back to `BasicConfigurator` (DEBUG+ to stdout) because no `logback.xml` was bundled in the JAR
+- Fixed internal documentation cross-references to use `.md` extensions for proper link resolution
