PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Fix typo in FIPS parameter format The FIPS parameter value contains a typo: FIPS=140-3 uses an equals sign instead of a hyphen. It should be FIPS-140-3 to match the correct format used elsewhere in the release notes (e.g., in the Features section). release-notes/opensearch-sql.release-notes-3.6.0.0.md [52] -* Add gradle.properties file to build sql with -Pcrypto.standard=FIPS=140-3 by default ([#5231](https://github.com/opensearch-project/sql/pull/5231)) +* Add gradle.properties file to build sql with -Pcrypto.standard=FIPS-140-3 by default ([#5231](https://github.com/opensearch-project/sql/pull/5231)) Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies a real typo where FIPS=140-3 uses an equals sign instead of a hyphen. The correct format FIPS-140-3 is used elsewhere in the release notes (line 22), making this an inconsistency that should be fixed.	Medium

[RyanL1997]

should be under 'Infrastructure' I think

[Swiddis]

It was tagged as a feature, #5155

FIPS in general is a security feature, it shows up now in our security integ tests, so it's debatable. Will just leave it to avoid re-approvals
