Once precommit's getCacheEntry is back, looks good to merge

Looks good to me! Added a few small suggestions

It looks like we need to add a link for this (and 2.3.0) at the bottom of the file:

For the nested lists to render properly for me, I had to add a few newlines:

 * EBS volume type for worker nodes has been changed from ``gp2`` to ``gp3``. This will result in node replacement. Workload migration should still be managed by AWS.

+**What's new in 2.4.0 (#119):**
 
 * **Custom AMI Support**:
+
   * Added support for conditionally specifying custom AMIs for EKS node groups.
   * New parameters:
+
     - ``CustomAMIImageType``: Corresponding image type (e.g., ``AL2023_x86_64_STANDARD``, ``AL2_x86_64``).
     - ``CustomEKSAMI``: AMI ID to use for worker nodes. If ``CustomAMIImageType`` is set, one isn't required to set ``CustomEKSAMI``.
+
   * Conditional logic ensures that these settings are only applied when explicitly provided.
 
 * **Cluster Version Parameterization**:
+
   * Introduced ``EksClusterVersion`` parameter to allow template users to control the Kubernetes version.
   * If this parameter is not set, AWS will default to the version already in place.
 
 * **Launch Template Enhancements**:
+
   * Node group now uses a versioned launch template reference. This will support inplace changes rather than entire nodegroup replacement where possible.
   * Custom AMI ID is injected into the launch template conditionally, based on user input.
 
 * **EBS Improvements**:
+
   * Changed block storage type from ``gp2`` to ``gp3`` in the launch template for better performance and cost optimization.

I tested locally with pip install restview and restview CHANGELOG.rst
