+## [1.5.4]
+
+### Fixed
+
+- Fix false-positive orphan warnings on Windows: file paths from the filesystem
+  are now normalized to forward slashes before comparing against markdown
+  references ([#63]).
+- Fix code block detection on Windows: fenced code block regexes now handle
+  CRLF line endings, fixing zero code-block counts when files are checked out
+  with Windows-style line endings.
+- Fix backslash paths in token count keys, result messages, and GitHub Actions
+  annotations on Windows.
+- Add Windows (`windows-latest`) to CI test matrix.
+
+## [1.5.3]
+
+### Fixed
+
+- Contamination warnings now only fire when multiple application programming
+  languages are detected. Skills containing only auxiliary languages (shell,
+  config formats) no longer trigger false positives ([#60], [#62]).
+
 ## [1.5.2]
