 # Change Log for RCCL
 
 Full documentation for RCCL is available at [https://rccl.readthedocs.io](https://rccl.readthedocs.io)
+## [UNRELEASED]
+### Added
+- Compatibility with NCCL 2.9.9
 
-## [Unreleased]
+## [RCCL-2.8.4 for ROCm 4.3.0]
+### Added
+- Ability to select the number of channels to use for clique-based all reduce (RCCL_CLIQUE_ALLREDUCE_NCHANNELS).  This can be adjusted to tune for performance when computation kernels are being executed in parallel.
 ### Optimizations
 - Additional tuning for clique-based kernel AllReduce performance (still requires opt in with RCCL_ENABLE_CLIQUE=1)
-
+- Modification of default values for number of channels / byte limits for clique-based all reduce based on device architecture
 ### Changed
 - Replaced RCCL_FORCE_ENABLE_CLIQUE to RCCL_CLIQUE_IGNORE_TOPO
 - Clique-based kernels can now be enabled on topologies where all active GPUs are XGMI-connected
 - Topologies not normally supported by clique-based kernels require RCCL_CLIQUE_IGNORE_TOPO=1
+### Known issues
+- Managed memory is not currently supported for clique-based kernels
+
+## [RCCL-2.8.4 for ROCm 4.2.0]
+### Added
+- Compatibility with NCCL 2.8.4
+
+### Optimizations
+- Additional tuning for clique-based kernels
+- Enabling GPU direct RDMA read from GPU
+- Fixing potential memory leak issue when re-creating multiple communicators within same process
+- Improved topology detection
+### Known issues
+- None
 
 ## [RCCL-2.7.8 for ROCm 4.1.0]
 ### Added
