+## [v37r0](https://gitlab.cern.ch/gaudi/Gaudi/-/releases/v37r0) - 2023-09-14
+This is the first major release of Gaudi in a while. This was made necessary to be able to incorporate
+a number of backward incompatible changes that have been kept in the backburner until now.
+
+The main (backward incompatible) changes are:
+- clean up and improvements to the new monitoring infrastructure
+ - custom sinks have to be adapted
+- drop of `LIKELY` and `UNLIKELY` preprocessor macros
+ - they have been deprecated for long, but waiting for a major release to effectively
+ remove the implementation
+- make the subdirectory `GaudiAlg` optional
+ - still enabled by default, it's not really backward incompatible, but the refactoring
+ implies that some minor adaptations might be needed in downstream code
+
+Since this a major release we took the occasion to update the versions of the hooks in
+`pre-commit-config.yaml` and that caused some minor changes in the formatting.
+
+In addition we have the usual batch of fixes and some new features.
+

+- Implement helper class for arrays of counters (gaudi/Gaudi!1484)
+- Fire ContextIncident `CONNECTED_NTUPLE_OUTPUT` when opening a ntuple file in RFileCnv (gaudi/Gaudi!1478)
+- Check errors in histograms unit tests on top of bin content (gaudi/Gaudi!1480)
+- Add `GAUDI_PGO` CMake options to enable builds with Profile Guided Optimizations (gaudi/Gaudi!1472)

+- Never rely on default Gitlab Docker image in gitlab-ci (gaudi/Gaudi!1491)
+- Fix performance of Counter destructor by using appropriate containers in Sink (gaudi/Gaudi!1477)
+- Hide `RdtscClock.h` to non x86_64 builds, needed for aarch64 (gaudi/Gaudi!1479)
+- Minor fix in a CMake error message (gaudi/Gaudi!1481)
