* Fixed image link whitespace handling (Brion's complaint, r39662) * Added fuzz test capability to parserTests.php * Added __destruct() functions to Parser and Language, and called them explicitly from parserTests.inc, to avoid unconstrained memory usage during fuzz testing. * Added unified diff to output of Parser_DiffTest * Fixed whitespace change in Parser::doTableStuff() (found by fuzzing) * Added feature to RELEASE-NOTES which I'd committed last time but forgotten to note: <gallery> will accept image names with no "Image:" prefix (rediscovered by fuzzing) * Limit memory usage in Title::getInterwikiLink() * Fixed chronic fail of all interwiki link parser tests (hid Siebrand's complaint, r39464) * Fixed chronic fail of one of the LanguageConverter parser tests. Was actually an ignored bug.
