 Changes
 =======
 
+0.0.2 (2019-04-23)
+------------------
+
+* FEATURE: New flag ``-j`` for JSON-formatted log output
+* FEATURE: New field ``command`` allowed in XML configuration files for filtering for command strings with regular expressions
+* FEATURE: All fields in ``include`` and ``exclude`` tags, e.g. ``extension`` or ``uid``, become optional / implicit and can be omitted.
+* FEATURE: (UNTESTED) Mac OS X support. Test framework still relies on Linux.
+* FIX: Several implementations of FUSE calls such as truncate did rely on the assumption that the current working directory of the file system process would not change. This was risky. LoggedFS-python does also NOT change the current working directory anymore on its own.
+* Code cleanup
+

+LoggedFS-python can use an XML configuration file if you want it to log operations only for certain files, for certain users, or for certain operations. LoggedFS-python is fully compatible with configuration files in LoggedFS' original format. Yet it can also handle additional fields (e.g. the ``command`` field).
