Hello, PCRE (1) is end of life and unmaintained now (see below). Not a huge problem, because PCRE2 has been supported since haproxy 1.8.
However going forward (haproxy 2.5+) should we: - warn when compiling with PCRE? - remove PCRE support? - both, but start with a warning in 2.5? - maintain PCRE support as is? PCRE is end of life and unmaintained : from http://pcre.org/ > The older, but still widely deployed PCRE library, originally released in > 1997, > is at version 8.45.
