Greptile Summary

This PR adds five missing changelog entries to the [Unreleased] section for PRs #2918, #3063, #3068, and #3069 (two entries for #3069). All entries are well-formatted and correctly placed in their respective Added, Improved, and Fixed subsections.

Note: the PR description lists PRs #2918, #3063, and #3068 under "Entries already present," but the diff shows those entries being newly added by this PR. The description appears to have been written inaccurately — the actual changelog changes are correct.

Confidence Score: 5/5

Safe to merge — documentation-only change with no code impact.

All five new entries are correctly formatted, placed in appropriate subsections, and reference valid PR numbers. No code changes are included. The only discrepancy is a cosmetic inaccuracy in the PR description, which does not affect the changelog content itself.

No files require special attention.

Vulnerabilities

No security concerns identified. This PR contains only CHANGELOG.md documentation changes.

Important Files Changed

Filename	Overview
CHANGELOG.md	Adds 5 new entries across Added/Improved/Fixed sections for PRs 2918, 3063, 3068, and 3069 — all well-formatted and accurately categorized; PR description slightly mischaracterizes which entries were already present.
