We cut routing-release 0.183.0 today morning. 

Release highlights: 
  • Operator can specify HTTP headers to be added by Gorouter to responses details
  • Operator can specify HTTP headers to be removed by Gorouter from the responses details
  • We have updated locket to the latest commit details
  • Fixed an issue introduced with the move to BPM for TCP Router on accumulating TCP-Router HAProxy instances details
  • With the move to BPM, operators should use the syslog release for access log streaming. enable_access_log_streaming is no longer supported in the Gorouter details
  • Gorouter stdout logs includes vcap_request_id so operators can correlate the stdout logs with access logs for easier debugging of issues details
  • Route registrar now supports registration of TCP routes details
  • When an application instance crashes while processing a request Gorouter now returns an error and takes the backend out of the pool temporarily, without retrying another backend details
  • We have updated from Cflinux2 to Cflinuxfs3 details
  • We are still evaluating the issue we are having with performance reports and have not been able to get a root cause details

Routing team

@Gabriel Rosenhouse brought up a important point that we wanted to call out.

  • When an application instance crashes while processing a request Gorouter now returns an error and takes the backend out of the pool temporarily, without retrying another backend details
This change may cause increased 502 rates for existing apps. Let us know if you have any questions.
