FB should consider migrating to new PCRE library #755
Description
With the release of Debian Trixie a couple days ago as of this writing, Debian has fully deprecated and entirely removed pcre3 from its "stable" package repository, and all future repos. This change is going to filter down to the Debian derivatives fairly quickly, and eventually to Debian off-shoots like Ubuntu as well. It is reasonably likely that non-Debian distros will follow suit sooner or later.
pcre3 has been end-of-life and unmaintained for a number of years now (it has officially not seen any update in over 4 years), and even the PCRE Project itself has long been urging developers to migrate their projects to pcre2, which (despite the confusing name) is the newer, current and still actively developed PCRE library.
While I realize that it is still entirely possible to build pcre3 independently and not rely on a distro's packaged version, I think the writing is on the wall, especially with pcre3 no longer being maintained. It would probably behoove the FB project to start looking into migrating its PCRE dependency to the current and actively maintained pcre2 library.
