Major redesign of rendering pipeline that separates pages saved with MCE from pages saved with the plaintext editor (full description in long commit message) - Pages are now stored with an extra metadata field called page_format which is "wikitext" or "xhtml" - New $flags parameter + RENDER_* constants added that control RenderMan::render() behavior - Several other changes: * Added a sprite API for Javascript and made editor use sprites when possible * Removed a number of config options from the default install schema, replaced with second parameter to getConfig() calls * MessageBox in editor mostly replaced with miniPrompt * A few bugfixes related to password changes (registration didn't even work) * Rewrote the bitfield compression algorithm used to serialize allowed MIME types * Fixed some typos in language files and strings * Fixed a Text_Wiki bug in Heading parser
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:

eb8b23f11744 Two big commits in one day I know, but redid password storage to use HMAC-SHA1. Consolidated much AES processing to three core methods in session that should handle everything automagically. Installation works; upgrades should. Rebranded as 1.1.6.

9cdfe82c56cd Major underlying changes to namespace handling. Each namespace is handled by its own class which extends Namespace_Default. Much greater customization/pluggability potential, at the possible expense of some code reusing (though code reusing has been avoided thus far). Also a bit better handling of page passwords [SECURITY].

acb7e23b6ffa Massive commit with various changes. Added user ranks system (no admin interface yet) and ability for users to have custom user titles. Made cron framework accept fractions of hours through floating-point intervals. Modifed ACL editor to use miniPrompt framework for close confirmation box. Made avatar system use a special page as opposed to fetching the files directly for caching reasons.
