for me it has varied based on the product type and scope, i.e release note for everyone like on a mobile app release or a SaaS platform, vs a tenant specific customized release. There are multiple ways to single source it, and now LLMs can help you out a bit.

If you just need a simple thing, query what you are releasing (from jira or whatever tracking system you are using) and package them up into categories of features/bug fixes and keep the release notes general.

if it's important to have an accurate curated set of release notes, create a field in your bug db for external release notes---leave those for tehncical product managers, support etc to edit as they want. THen you can have internal and external ones.

you always need to review for language and sensitive data, so human review (but again LLMs are helpful now fo this stuff too)
