Hey there - I've reviewed your changes - here's some feedback:
- Several release note entries contain obvious typos (e.g.,
senstive,senstivity,versio,enbled) and minor grammatical issues; it would be good to clean these up for a more polished 0.296 release page. - Some bullets appear duplicated or redundant (e.g., the compression codecs entry mentions ZSTD/ORC/Parquet twice, and the Postgres timestamp fix description is repeated); consider deduplicating or consolidating these for clarity.

**suggestion (typo):** Use the standard "PostgreSQL" capitalization.
Consider renaming this heading to "PostgreSQL Connector Changes" to match the proper database name and maintain consistency.
Suggested implementation:
```
PostgreSQL Connector Changes
```
1. Ensure this section header actually exists in `release-0.296.rst` with the exact spelling "Postgresql Connector Changes". If the capitalization or spacing differs, adjust the `SEARCH` text accordingly.
2. Confirm that the underline below the heading (the line of `_` characters) is at least as long as the new heading text; Sphinx/RST requires the underline length to be ≥ the heading length. If necessary, extend the underline by one character to keep formatting correct.

Thanks for the updated release notes @tdcmeehan! I pulled the updated branch and run a new local doc build, tested the new links, everything present looks good.
I see these items as done:
- Identify any entries that should not be in the Release Notes, and delete them
- Revise some of the existing entries as needed, to
- Show the user-facing effect of the PR to the reader
- Make the value of the change in the PR understandable to a non-developer
What I see left to do is:
- Review the PRs in the Missing Release Notes section of this PR
- Identify any of those PRs that should have release notes added for this release
- Write (work with the PR author as needed) any needed release notes and add them
(Note: You may have decided there are none that need to be added - the result would be the same in the file.)
- Select notable entries and copy those into the Highlights topic
- Identify any entries that should be copied into the Breaking Changes topic, or delete the Breaking Changes topic if there are no breaking changes in this release
- Squash commits and merge

@steveburnett I made a bunch of edits, do you mind reviewing again? I already added the missing release notes that I felt were noteworthy. There is no need to squash manually anymore, as the only Github merge command allowed will automatically squash commits. |
