**What's New**

- Added `--kms_query_params` option to pass custom query parameters to KMS URLs, enabling flexible KMS integration without modifying core configurations.

- Added `--encrypt_audio` option to explicitly enable audio track encryption in multi-key packaging workflows, giving operators finer control over per-track encryption policy.


**What's Changed**

- Updated the underlying Shaka Packager engine to v3.7.0, incorporating upstream stability improvements and format support enhancements.

- Audio tracks are now excluded from encryption by default in multi-key packaging; use `--encrypt_audio` to opt in where full-track encryption is required.

- Content information is no longer automatically embedded in the manifest; this is now an opt-in feature to reduce unintended metadata exposure in packaged output.
