0.297.0

Changes

• 🐛FIXES KNOWN ISSUE Gorouter now correctly returns the status code provided by backends for workflows using 100-continue, or other 1xx interim status codes. Thanks for catching this @plowin @domdom82 and thanks @geofffranks for the quick fix!
• 🐛The TLS listener for the health status endpoint in gorouter now handles custom cipher-suites that do not include any of the required HTTP/2 ciphers. Thanks @MarcPaquette + @geofffranks!
• 🐛 Failing to establish a TCP connection to a backend no longer causes a panic when setting up a WebSocket connection. Thanks @domdom82!
• ✨The health status endpoint for gorouter is now able to log error messages encountered when it starts up, to aid in troubleshooting. Thanks @MarcPaquette and @geofffranks !
• ✨Gorouter now provides a missing_content_length_header metric that will flag requests that would have been hit by Golang 1.22's new check to reject requests that have an empty content-length header. This can be used to determine if an environment will be affected by disabling the go.httplaxcontentlength gorouter property. Thanks @mariash!
  • NOTE: The metric is counting requests unaffected by the new golang behavior and will be updated in 0.298.0+, where it is also renamed to empty_content_length_header.
• ✨Route registrar now allows operators to specify load blancing algorithms for individual routes. Thanks @b1tamara and @domdom82 !
• Bumped to golang 1.22.3
