Updates express from 4.22.1 to 4.22.2

Release notes

Sourced from express's releases.

v4.22.2

What's Changed

• fix: restore >20 array parsing for req.query repeated keys (8d09bfe6)
  • This also unifies array-cap behavior across notations. Indexed notation (a[0]=...) was historically capped at qs's default arrayLimit of 20 even in older qs versions; after this change it also allows up to 1000 items.
• deps: qs@~6.15.1
• deps: body-parser@~1.20.5

New Contributors

• @​suuuuuuminnnnnn made their first contribution in expressjs/express#7021
• @​SAY-5 made their first contribution in expressjs/express#7181

Greptile Summary

This is a routine dependabot bump updating express from 4.22.1 to 4.22.2, which pulls in qs 6.15.2 and body-parser 1.20.5 as transitive dependency updates.

• qs 6.14.2 → 6.15.2: Several stringify crash-fixes (null/undefined entries in arrayFormat: 'comma', filter-array entries) and a parse fix for nested bracket groups.
• express 4.22.1 → 4.22.2: Restores >20 array parsing for req.query repeated keys and unifies array-cap behavior across indexed and repeated-key notations (now capped at 1000 instead of 20).
• body-parser 1.20.4 → 1.20.5: Minor update as a co-dependency of express.

Confidence Score: 5/5

Safe to merge — all changes are automated dependency version bumps with no application logic touched.

Only package.json and package-lock.json are modified. The three updated packages (express, qs, body-parser) all receive patch-level bug fixes — crash fixes in qs stringify/parse and a regression fix in express's req.query array parsing. Integrity hashes in the lockfile are consistent with the published versions. No application code is affected.

No files require special attention.

Important Files Changed

Filename	Overview
package.json	Bumps express from ^4.21.1 to ^4.22.2 to pull in bug fixes in qs and body-parser
package-lock.json	Lockfile updated to reflect express 4.22.2, body-parser 1.20.5, and qs 6.15.2 with their new integrity hashes
