 ## [Unreleased][]
 
+## [v31r0][] - 2019-02-11
+The main reason for this major release is to the change of the `Algorithm` base
+class with a re-entrant `execute` method (#47, !703). For backward compatibility the
+base class for algorithms is `Gaudi::Algorithm`, while the name `Algorithm` in
+the top level namespace is used for a backward compatible implementation. This
+change also required a backward incompatible change in the `IAlgorithm`
+interface, so some code may require adaptation.
+
+We also took the occasion to update the version of `clang-format` we use from
+3.9 to 7, and to switch Python formatting from `autopep8` to `yapf` (!788).
+Because of the differences (fixes and new features) in the versions of
+`clang-format`, we also updated the style rules.
+
+As of this version, Gaudi requires C++17 compatible compiler.
+C++14 compatibility is not required in merge requests, nor guaranteed on the
+_master_ branch.
+
+On top of that, we have the usual collection of minor fixes and improvements.

+- Introduced `CPUCrunchSvc` (!840)
