The prior release (5.2.0) included an erroneous breaking change related to the extended query parser. There is no actual security vulnerability associated with this behavior (CVE-2024-51999 has been rejected). The change has been fully reverted in this release.
A deprecation warning was added when using res.redirect with undefined arguments, Express now emits a warning to help detect calls that pass undefined as the status or URL and make them easier to fix.
