Git 2.14.0 got released last week with release notes that recommend using pcre2 instead of pcre1: https://github.com/git/git/blob/master/Documentation/RelNotes/2.14.0.txt#L25
I've already seen e.g. Debian, Arch and Fedora change their dependency from pcre1 to pcre2 for Git. Since a lot of systems use git as one or their core packages I expect this'll lead to a lot more installation & use of the library. The things that used pcre2 on a typical Linux system[1] were pretty obscure. 1. https://www.archlinux.org/packages/extra/i686/pcre2/ -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
