Breaking Changes

●Issue #1

The incoming request path is now cleaned before being used to match router rules and sent to backends. Any /../, /./ or duplicate slash segments in the request path are interpreted and/or collapsed. This behavior started in v2.11.24 and may affect routing if paths relied on un-sanitized input.

Migration Steps

  1. 1
    Review the request path sanitization change introduced since v2.11.24 and consult the migration guide to ensure existing routing rules function as expected with cleaned paths.

Release Summary

This release focuses heavily on security by fixing three CVEs and implements request path sanitization for improved security, which may require configuration review.
