Version 6.x-1.4
Packaging errors - wrong files in 6.x-1.2 and 6.x-1.3 releases.
Version 6.x-1.2
Removed t() functions from phpfreechat.install to comply with later versions of Drupal 6.x (tested on Drupal 6.34).
Minor change in phpfreechat.inc and parameters.txt for compatibility with phpFreeChat 1.7 (prior version had been tested with phpFreeChat 1.2).
Updated the INSTALL.txt instructions to clarify and update some details.
Reformatted all files to comply with Drupal formatting standards.
Chatbox options were not displaying on the "Add content" form when they should have been. Now they are.
The block options were not previously working. Now they are. You can configure blocks showing who is chatting across all rooms, or in up to two specific rooms (configurable).
