-**DEPRECATIONS**

 **ENHANCEMENTS**
-- Add support for p6e-gb200 instances via capacity blocks.
-- Echo chef-client log when a node fails to bootstrap. This helps with investigating bootstrap failures in cases CloudWatch logs are not available.
+- Add basic support for p6e-gb200 instances via capacity blocks. AL2 is not supported and IMEX configuration must be done manually.
+- Chef-client logs are now available in the instance console to help investigating node bootstrap failures in cases CloudWatch logs are not available.
 - Add `build-image` support for kernel 6.12 of Amazon Linux 2023. The official ParallelCluster Amazon Linux 2023 AMIs use kernel 6.12.
 - Support `prioritized` and `capacity-optimized-prioritized` Allocation Strategy. This allows users to prioritize subnets for instance placement to optimize costs and performance.
+- Support DCV on Amazon Linux 2023.
 
 **CHANGES**
 - Install nvidia-imex for all OSs except AL2.
 - Ubuntu 20.04 is no longer supported.
 - Remove `UnkillableStepTimeout` from slurm.conf and let slurm set this value.
-- Support DCV on Amazon Linux 2023.
 - Upgrade Python runtime used by Lambda functions to python3.12 (from python3.9).
 - Remove `berkshelf`. All cookbooks are local and do not need `berkshelf` dependency management.
-- The build-image command now deploys a global role that is used to automatically delete the build-image stack after images either succeed or fail the build.
-  The role is meant to exist even after the stack has been deleted. This is to prevent build-image stack deletion failures, reported in https://github.com/aws/aws-parallelcluster/issues/5914.
 - Add the configuration parameter `HeadNode/SharedStorageEfsSettings/Encrypted` to enable encryption on the EFS file system used for the head node internal shared storage.
 - Add validator that warns against using non GPU instances with DCV.
 - Upgrade Slurm to version 24.11.6 (from 24.05.8).

+- The `build-image` command now deploys a global role that is used to automatically delete the build-image stack after images either succeed or fail the build.
+  The role is meant to exist even after the stack has been deleted. This is to prevent build-image stack deletion failures, reported in https://github.com/aws/aws-parallelcluster/issues/5914.
 - Fix an issue where Security Group validation failed when a rule contained both IPv4 ranges (IpRanges) and security group references (UserIdGroupPairs).
 - Fix `build-image` failure on Rocky 9, occurring when the parent image does not ship the latest kernel version on the latest Rocky minor version.
 - Fix AWS Batch cluster creation failures in China when the OS is Amazon Linux 2023.
 - Fix cluster id mismatch issue by deleting the file `/var/spool/slurm.state/clustername` before configuring Slurm accounting.
