📝 Walkthrough

Walkthrough

Updated changelog table in docs/changelog/index.md to add a git hash column alongside the existing date and change columns. The table now includes multiple dated documentation and architecture entries with corresponding git hashes, including entries for Ceph, ROOK, Prysm, Arbiter, and Chorus, concluding with a "Change log created" entry tied to a specific git hash.

Poem

🐰 A changelog grows with time and care,
Each hash a snapshot, noted there,
From Ceph to Chorus, tracked with pride,
The git commits now side-by-side!
History written, crystal clear—
What changed when, is now quite dear. 🌟

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title 'doc: add entries to changelog' is vague and generic. While it references the changelog, it doesn't specify what entries are being added or why, using imprecise language that doesn't clearly convey the main purpose of the changeset.	Provide a more descriptive title that specifies the key addition, such as 'doc: add git hash column to changelog' or 'docs: populate changelog with git commit hashes'.

"2025-03-12" in the table row should be "2026-03-12" to keep chronological order
with surrounding entries; update the date literal in the docs/changelog index
table (the row containing "Add Arbiter documentation | 26891975") to
"2026-03-12".
- Around line 17-18: Remove the duplicate changelog entry that appears twice ("|
2026-03-31    | Add CephFS summary to arch    | fd962649  |"); keep a single
instance of that line in docs/changelog/index.md so the changelog is
deduplicated and consistent.

Thanks for the changes Zac. I think this is more of a commit list than a changelog.

Could we make it a bit more changelog like, we can group related documentation changes and describing the actual purpose/impact? we will have less entries on the list but will be more informative,

the CephFS entry appears twice with the same hash.

The git hashes are useful, but the change descriptions should be a bit more meaningful for reviewers/readers.
