MediaWiki is a Web-based collaborative editing environment originally built for the online encyclopedia project Wikipedia. It’s geared to support a large number of users and pages. It requires PHP and MySQL. Various minor bugfixes were made, as well as a security fix for a remote code execution vulnerability in common configurations. Wiki-friendly table markup is now available, and interface localizations can optionally be edited live. A new XML-wrapped export function should aid third-party utilities and future cross-wiki relocation of pages. Various bugfixes were made.
This release fixes a major bug in 1.2.0rc4, which could delete an existing wiki instead of upgrading it when using the web installer. This release fixes various bugs: in-place install with a non-root MySQL user, history diff checkboxes bug on titles with ampersands, printable links on special pages with parameters, and IP blocking without memcached. Extra E_NOTICE warnings have been turned off. Installation fixes were made for Apache 2, MySQL with blank root password, and root-level URLs. Minor search, email-user, and Recent Changes fixes were also made. English/UTF-8 now has correct case conversion for title initial letters. This release features an edit blacklist for spam attacks and local interwiki redirects and removed more hard-coded “Wikipedia” strings in the localization.
The searchindex table type and Windows upload paths were fixed. Problems with certain numeric and UTF-8 titles were fixed. Installation is now faster and more reliable, particularly for upgrades from 1.2 command-line installs. Minor fixes were made to the debug log, watch tabs in editing, subcategory sorting, and new message notification caching. Custom namespaces can be added more easily from the config file without hacking the localizations. A traditional Chinese localization was added.
