-- Introduce tagging of individual changes (revisions, logs, and on recentchanges). The tags are customisable, and currently settable by the Abuse Filter and by the TorBlock extension. The tags can be styled on the various pages on which they appear.
-- Introduces a schema change, three new tables (valid_tag, change_tag, and tag_summary).
* Remove one dupe call of addExtensionStyle from SpecialAbuseFilter::execute
* Bump $wgAbuseFilterStyleVersion per CSS changes in r46325
* Add a space between drop down and submit button
* Consolidate details on the last edit.
* Allow specification of a warning message to display instead of the standard warning (was already implemented in code, but there was no UI for it.
* Reimplement tools, starting with a spiffy AJAX expression tester. Didn't bother implementing as non-AJAX, as it's just an extra.
* Change exchange protocol between native parser and PHP app. Resulted in 2-3-fold performance boost.
* Fix minor bug from last night.
* Introduce a syntax check on-save.
* Introduce filter history (requires DB schema change).
* Deprecate now non-working /tools interface (will come back).
* Add a bunch of profiling, so we can figure out where performance bottlenecks are.
* Cache the in-object token cache in memcached, bringing per-condition run times from 4ms to a cooler 296us
* Improve normalisation: use AntiSpoof.
* Allow callers to prevent the use of a condition counter. It's kinda annoying in batch processes.
* Improved caching of tokenisation - reduces average time to process a condition from 4ms right down to 200us
* Some new modifiers, caching of modifier data.
* Allow matching on the changes made in an edit (added/removed lines, etc)
* Improve display of variables in details view - standardise the table size, add white-space: pre, font-family: monospace.
* Improve modifiers: add htmlencode/htmldecode/urlencode/urldecode.
* Add 'abuse filter tools', currently consisting of a testing ground for the modifiers. In future, may include facilities for testing filters against user contributions, recent changes, or other sources.
* Disallow more than 100 condition-checks per action.
* Disallow filters which are misbehaving (more than 5 matches, constituting more than 5% of recent actions)
* Display statistics for all filters (percentage of times the condition limit is reached, and percentage of times some filter is matched), and individual filters (percentage of times it's matched).
