Comment 1 Stephen Greene 2020-10-01 15:22:44 UTC

I’m adding UpcomingSprint, because I was occupied by fixing bugs with higher
priority/severity, developing new features with higher priority, or developing
new features to improve stability at a macro level. I will revisit this bug
next sprint.

The merge made into "v3.11.273-1_2020-08-30.1" release version with the included "haproxy18-1.8.23-3" package version. It is noted that the headers now contain CR-LF linebreaks:
