 **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.
-- 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.
-- Add `build-image` support for Amazon Linux 2023 AMIs based on kernel 6.12 (in addition to 6.1).
+- 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.

 **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>.
