Majorly reworked Javascript runtime stuff to use on-demand loading. - Runtime reduced to only AJAX library + very common functions, ~50K total - Almost all specific functionality loaded on demand using synchronous XHR - Crypto functions consolidated into crypto.js - Much testing still to be done - ACL editor known not working under firefox - Some other components (autofill, theme/rank managers) not ported yet
