 **ENHANCEMENTS**
-- Add support for P6e-GB200 instances. ParallelCluster sets up Slurm topology plugin to handle P6e-GB200 UltraServers. See limitations section for important additional setup requirements.
-- Add support for P6-B200 instances for all OSs except AL2.
+- Include drivers for P6e-GB200 and P6-B200 instances. ParallelCluster sets up Slurm topology plugin to handle P6e-GB200 UltraServers. See limitations section for important additional setup requirements.
+- Support `prioritized` and `capacity-optimized-prioritized` Allocation Strategy. This allows users to prioritize subnets for instance placement to optimize costs and performance.
 - Add `build-image` support for Amazon Linux 2023 AMIs based on kernel 6.12 (in addition to 6.1).
+- Support DCV on Amazon Linux 2023.
+- Echo chef-client logs in the instance console when a node fails to bootstrap. This helps with investigating bootstrap failures in cases CloudWatch logs are not available.
 
 **LIMITATIONS**
 - P6e-GB200 instances are only tested on Amazon Linux 2023, Ubuntu 22.04 and Ubuntu 24.04.
-- Using IMEX on P6e-GB200 requires additional setup. Please refer to <PLACE_HOLDER for the tutorial link>.
+- Using IMEX on P6e-GB200 requires additional setup. Please refer to the dedicated tutorial in our public documentation.
+- P6-B200 instances are only tested on Amazon Linux 2023, RHEL9, Ubuntu 22.04 and Ubuntu 24.04.
 
 **CHANGES**
-- Install nvidia-imex for all OSs except AL2.
-- Remove `berkshelf`. All cookbooks are local and do not need `berkshelf` dependency management.
+- Install nvidia-imex for all OSs except Amazon Linux 2.
 - Remove `UnkillableStepTimeout` from slurm.conf and let slurm set this value.
+- Upgrade Python runtime used by Lambda functions to Python 3.12 (from 3.9). See Lambda Documentation for important information about Python 3.9 EOL: https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html
+- Support encryption of EFS file system used for the head node internal shared storage via a new configuration parameter `HeadNode/SharedStorageEfsSettings/Encrypted`
+- Add validator that warns against using non GPU instances with DCV.
 - Upgrade Slurm to version 24.11.6 (from 24.05.8).
 - Upgrade EFA installer to 1.43.2 (from 1.41.0).

 **BUG FIXES**
-- Fix a race condition in CloudWatch Agent startup that could cause nodes bootstrap failures.
-- Fix cluster id mismatch issue by deleting the file `/var/spool/slurm.state/clustername` before configuring Slurm accounting.
+- Prevent `build-image` stack deletion failures by deploying a global role that automatically deletes 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. See 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 cluster id mismatch issue which causes cluster update failures when slurm accounting is used.
+- Fix a race condition in CloudWatch Agent startup that could cause node bootstrap failures.
 
 **DEPRECATIONS**
+- The configuration parameter `LoginNodes/Pools/Ssh/KeyName` has been deprecated, and it will be removed in future releases. The CLI now returns a warning message when it is used in the cluster configuration.
+  See https://github.com/aws/aws-parallelcluster/issues/6811.
 - Ubuntu 20.04 is no longer supported.
