I build & use the latest Postfix release from source instead of depending on
distro packages.
I use regex alot, including in Postfix. I try to keep up to date with upstream
PCRE too.
PCRE has released a v2, where all new features appear, and maintains (bug-fixes
only) v1.

Versions
There are two major versions of the PCRE library. The newest
version, PCRE2, was released in 2015 and is at version 10.21. The original,
very widely deployed PCRE library, originally released in 1997, is at version
8.38, and the API and feature set are stable—future releases will be for
bugfixes only. All new future features will be to PCRE2, not the original PCRE
8.x series.
Currently my Postfix build links to latest PCRE v1
ldd /usr/local/sbin/postfix | grep pcre
libpcre.so.1 => /usr/local/lib64/libpcre.so.1
(0x00007f84d34b0000)
libpcrecpp.so.0 => /usr/local/lib64/libpcrecpp.so.0
(0x00007f84d32a6000)
What plans are there, if any, to move to using PCRE v2 in Postfix?

Just wanting to understand if & when I'd have to plan for using it.
Thanks
