 Plexus Archiver Release Notes
 ========================================================================
 
+Plexus Archiver 4.0.0
+---------------------
+
+**NOTE:** Because 3.7.0 introduced backward incompatible changes
+in the API (new methods in interfaces) we bumped the Plexus Archiver
+version to 4.0.0.
+
+Plexus Archiver 4.0.0 requires Java 7.
+
+### Improvements
+ * [Issue #105][issue-105] - Fixed performance regression introduced
+ in Plexus Archiver 3.0.2. Affected are systems where the retrieval of
+ a file's user and group attributes is costly operation.
+ * [Pull Request #106][pr-106] - `PlexusIoZipFileResourceCollection`
+ performance is improved when working with signed Jar files.
+
+### Tasks
+
+ * [Issue #108][issue-108], [Issue #109][issue-109] - Updated dependencies:
+ `plexus-io` to 3.1.1 and `plexus-utils` to 3.1.1.
