I agree about filter. Having native JSON support is a nicety though, it's faster than a userland implementation. > However, I can think of a good argument for moving to PHP 5.2, which > is to stop the high rate of bit rot in 5.1 support.

After talking again on IRC with people today, I think we can safely break 5.1 in trunk (although lets not backport it). Once the 1.17 release is out, we should find a way to better update [2] so we can indicate that 1.17 will be the last release with 5.1 support. -Chad [0] http://www.mediawiki.org/wiki/Special:Code/MediaWiki/68760 [1] http://php.net/migration52 [2] http://www.mediawiki.org/wiki/Manual:Installation_requirements _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
