PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis 🔶 GTF-2389 - Partially compliant Compliant requirements: Changelog updated to include version 6.0.9 Release date set to 2026-01-30 in Changelog Fixed items descriptions improved (formatting and typos) Non-compliant requirements: Update 'version' field in 'package.json' (file is missing from the diff) Requires further human verification: Verify that all PRs in the release checklist have been handled (merged/rejected)

⏱️ Estimated effort to review: 1 🔵⚪⚪⚪⚪ The PR contains only minor text updates to a single Markdown file.

🏅 Score: 85 The Changelog update is correctly formatted, but the PR seems incomplete as it lacks the `package.json` version bump required for a release.

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Missing Version Manifest Update The Changelog indicates a release of version 6.0.9, but the package.json file is not included in the diff. Standard release procedures require updating the version field in the package manifest to match the Changelog. ## [6.0.9] - 2026-01-30
