PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🧪 No relevant tests

🔒 No security concerns identified

✅ No TODO sections

🔀 No multiple PR themes

⚡ Recommended focus areas for review Version Mismatch The jackson_annotations version is set to "2.21" (without patch version) while jackson and jackson_databind are set to "2.21.1". This inconsistency should be verified to ensure it is intentional and that the annotations artifact actually uses a different versioning scheme (no patch version suffix). jackson_annotations = "2.21" jackson = "2.21.1" jackson_databind = "2.21.1"
