Thanks for the release preparation! A few observations for future releases:

Minor suggestions for improvement:

1. PR/Issue References: Consider including PR or issue numbers for all fixes when possible. While Unrecognized request argument supplied: verbosity when switching to another OpenAI model from gpt-5-2025-08-07 #7054 is referenced for the verbosity parameter fix, the AWS Bedrock and request cancellation fixes could benefit from similar references for better traceability.

2. Version Bump Process: I noticed the changeset was added but the version in src/package.json remains at 3.25.13. If this is handled automatically during the release process, that's perfect - just wanted to confirm this is intentional.

3. Changeset Naming: The changeset file uses the version number directly (v3.25.14.md). The typical changeset convention uses descriptive names (e.g., fix-verbosity-bedrock-cancellation.md) with versions determined during release. This might be a deliberate choice for your workflow though.

Great work on properly crediting all contributors! The changeset format and documentation are clear and well-structured.
