Changes since DRUPAL-6--1-0-RC1:

• Changes for coder.module.
• #413812 by Liam McDermott: fixed problem 'Private msgs... all are from me?', {pm_index} requires two records for both sender and receiver.
• #281861 by Liam McDermott: fixed problem where duplicate existing Drupal usernames cause the VBulletin user and posts to be skipped.
• #644882 by smk-ka: fixed unknown table: pm_tags_index error.
• #615472 by juan_g: fixed SQL error when database name has reserved words and special characters.
• by liammcdermott: Changed interface so it is streamlined (e.g. we no longer include information on what tests were run if they work), changed GETs to POSTs where there is a side-effect.
• #271268 by liammcdermott: fixed migration failing with multiple databases defined in settings.php
• by Liam McDermott: Fixed part of import that required the Drupal database user to have read access to the vBulletin database.
• by Liam McDermott: Added tentative support for Batch API. It broadly works, but still requires an extension to the PHP timeout.
• by Liam McDermott: Fixed 'package' in .info files.
