-# ZFS autobackup v3 - DEVELOPMENT VERSION
+# ZFS autobackup v3 - TEST VERSION
 
-This version is a work in progress.
-
-Please use the master-branch.
+New in v3:
+ * Complete rewrite, cleaner object oriented code.
+ * Python 3 and 2 support.
+ * Backward compatible
+ * Progressive thinning (via a destroy schedule. default schedule should be fine for most people)
+ * Cleaner output, with optional color support (pip install colorama). 
+  * Clear distinction between local and remote output.
+  * Summary at the beginning, displaying what will happen and the current thinning-schedule.
+ * More effient destroying/skipping snaphots on the fly. (no more space issues if your backup is way behind)
+ * Progress indicator (--progress)
+ * Better property management (--set-properties and --filter-properties)
+ * More robust error handling
+ * Prepared for future enhanchements.
