Usually a corner cases that have a different performance or exhibit bug fixes. If you meant PCRE library users, then yes, there are many changes. If you use only a basic part of the API, then porting to PCRE2 is easy. If you use more advanced things like JIT, callouts, or custom memory allocators, then the changes are so big the I don't recommend writing a C macro spaghetti code to accommodate both APIs. -- Petr _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
