I don't think the current code changes warrant a bump in version number.
What breaking changes are needed/desired?
using preg_replace_callback with an anonymous function (closure), which
requires php 5.3 or above, instead of preg_replace with an /e modifier
I tend to not want to abandon
I wonder if its time to have a discussion about the impact of the PHP 5.5
changes on PmWiki, specifically:
Should this be considered an opportunity to consider this a significant
upgrade of PmWiki - i.e. to version 3,
thus allowing some breaking changes,
and to restrict the effort to provide
