I've gone ahead and released 1.2.0 on account of a major bug in 1.2.0rc4 that could delete an existing wiki instead of upgrading it when using the web installer. At some point later a 1.2.1 should clean up some other minor installation issues and bugs.

See release notes for changes since 1.1.0: https://sourceforge.net/project/shownotes.php?release_id=226003
Changes from 1.2.0rc4:
Web install: * Serious upgrade bug fixed; an attempt to install over an existing database should now either upgrade gracefully or immediately fail, instead of wiping out your entire database (BUT BACKUP FIRST!) * Configuration tosses in output compression if available * Detects more image-related options (but uploads are still disabled by default)
Localizations: * Spanish localization has had most hard-coded "Wikipedia"s removed * French localization has been changed to UTF-8
Maintenance scripts: * rebuildrecentchanges.php works again * importPhase2.php for importing from very old format (pre-May 2002) wiki
