 ## Changelog
 
+### 1.6.1
+
+This release fixes an issue in which annotations such as `@foo-bar`
+and `@foo-` were incorrectly recognised as valid, and both erroneously
+parsed as `@foo`.
+
+Any annotation with `@name-*` format will now silently be ignored,
+allowing vendor-specific annotations to be prefixed with the tool
+name.
+
+Total issues resolved: **3**

 This release brings a new endpoint that make sure that you can't shoot yourself in the foot by calling ```registerLoader``` multiple times and a few tests improvements.
