+- Internal PMIx and PRRTe version:
+  - PMIx (v5.0.5). Repo: ``https://github.com/openpmix/openpmix``. Commit hash: ``707920c99de946a5c3a1850da457340f38c0caf2``.

+
+- Documentation Improvements
+  - Updated `coll tuned` rules file documentation to reflect changes in versioning and features.
+  - Updated CUDA-related networking documentation for consistency.
+  - Improved descriptions for `mpirun` options, including ``--pmixmca`` and ``--prtemca``.
+  - Fixed typos and formatting issues in `mpirun` man pages.
+
+- Functionality Enhancements
+  - Improved argument checking for ``MPI_Comm_create_from_group`` and ``MPI_Intercomm_create_from_groups`` to align with MPI 4.0 standards.
+  - Addressed potential race conditions in `PMIx_Group_construct` calls by adding discriminators.
+  - Fixed ``MPI_Wtime`` to initialize timing relative to ``MPI_Init`` for accurate session-level measurements.
+  - Added support for the `alltoall_algorithm_max_requests` parameter in the `coll tuned` rules file, maintaining backward compatibility.
+  - Introduced a version identifier for the `coll tuned` rules file for better parser handling.
+  - Adjusted MCA variable scopes across multiple components to allow setting via the `MPI_T` interface: `coll adapt,ucc, han, basic, hcoll`
+
+- Bug Fixes and Minor Enhancements
+  - Fixed community Jenkins build pipeline to handle branch commits properly.
+  - Resolved missing profiling symbols in the `mpi_f08` Fortran library.
+  - Corrected parameter mismatches in `coll/cuda` functions to avoid type issues.
