+## Major Changes
+- Make LCI more robust with the libfabric/cxi provider.
+  - new rendezvous protocol `write`.
+  - more assertions.
+- Remove sysconf from malloc critical path.
+  - Can be a major performance bottleneck on some platform (such as Frontera).
+- New LCI network backend: UCX.
+- Make LCI_sync_test/wait thread-safe against other LCI_sync_test/wait.
+
+## Breaking Changes
+

+- Enable the env var LCI_BACKEND_TRY_LOCK_MODE for ofi backend.
+- Let LCT Logger also report hostname.
+- Add a field (packet) to LCII_context_t.
+- Add sendmc: send medium with completion notification.
+- Improve LCT hostname setup.
+- Refactor performance counters: "on-the-fly" and "on-the-fly-lw" modes.
+- Add(lct): add argument parser to LCT.
+- Add(lct_tbarrier): add thread barrier to LCT.
+- Add(many2many_random): new example many2many_random.

+- Improve(ofi backend): better way to call fi_cq_readerr.
+- Make mpi_pt2pt also works for singleton case.
+- Add more log outputs to lct pcounter.
+- Fix lct_parse_pcounter.py.
+- Add try_lock_mode: none, global, global_b.
+- Improve PMI: add cmake option to turn off PMI1/PMI2 compilation.
+
