I've just upgraded pcre (Perl-compatible regular expression) library from version 8.12 to version 8.13 in F17.
Upstream says:
This is mainly a bug-fix release. There has been a lot of internal refactoring. The Unicode tables have been updated. The only new feature in the library is the passing of *MARK information to callouts. Some additions have been made to pcretest to make testing easier and more comprehensive. There is a new option for pcregrep to adjust its internal buffer size.
So the library itself should be fully compatible.
In addition, I've splitted bundled command line tools (pcretest and pcregrep) to standalone sub-package `pcre-tools' and compiled them against libreadline which makes interactive development of regular expressions in pcretest more friendly.
Thus if your package utilizes one of the two tools, please change dependency from `pcre' to `pcre-tools' or depend on the binary explictly. If this is due to pcregrep, you can consider using grep with `-P' option instead which is linked against pcre library either.
