 ### Removed
 ### Added
 
+## [4.27.0] - 2024-03-04
+
+### Changed
+
+- Move to use GEOSpyD Min23.5.2 on GMAO desktops
+
+## [4.26.0] - 2024-02-22
+
+### Changed
+
+- Move to Baselibs 7.18.1
+  - HDF5 1.14.3
+  - curl 8.6.0
+  - zlib 1.3.1
+
+## [4.25.1] - 2024-01-24
+
+### Fixed
+
+- Fix incorrect Open MPI module at NCCS SLES15
+
+## [4.25.0] - 2024-01-22
+
+### Changed
+
+- Moved to Baselibs 7.17.1
+  - Fix for NAG and ESMF 8.6.0
+- Update `g5_modules` to use GCC 11.4 as the backing C compiler on SLES 15 at NCCS
+  - This was done as it was discovered that xgboost was not building on SLES15 with Intel when using GCC 12. Until xgboost can be
+    updated to a newer version, this is the workaround.

 ## [4.22.0] - 2023-11-21
 
 ### Changed
 
-- Move back to Open MPI 4.1.5 with Intel on NCCS. This avoids a bug between GEOS' Intel debugging flags and MPI_Init with Open MPI 5.0.0 (see https://github.com/open-mpi/ompi/issues/12113)
