- The migration is easy, despite the PCRE2 API is somewhat different. If asked, I could help patching any code for PCRE2 support. - there's time to rework the API as in the patch, some points can be changed significantly - From what I could tell, the ratio of PECL exts using PCRE is low. In fact, I can't remember any, OFC there are be some. > This said, I'm presently +0.9 on accepting the RFC. > PCRE2 implements new features and fixes issues, while the legacy version only gets backports which are not optimal. At the time after two years PCRE2 release and the situation with PCRE support, switching seems a thing to me. The existing features are not broken, better Unicode support and improvements in functionality and memory handling speak for that. Regards Anatol
