+
+## QFS version 2.2.7
+
+## New features
+
+1. Support for python3. Native / platform independent python code is now
+compatible with python2 and python3, including QFS meta server web UI and meta
+server prune / backup script. QFS python module / bindings is only compatible
+with python3, and python2 is no longer supported.
+
+2. All required QFS shared libraries are now installed along with QFS python
+module. On macOS and linux runtime relative linker paths are now used in order
+to make installed QFS shared libraries relocatable. With this explicitly
+specifying QFS libraries runtime linkers paths with python module is no longer
+required.
+
+## Minor improvements
+
+1. Benchmarks mstress build now uses maven instead of ant, and now is included
+in QFS build and tarball by defaults.
+
+2. QFS python module is now built, tested, and included into QFS tarball if
+python 3.6 or higher is available.
