Most changes in Enswitch 3.4 purely add functionality, but some change or remove functionality. Here is a list of such changes. If any of these adversely affect you, please contact support as soon as possible.

• The callerid sent to handsets on inbound calls obeys the telephone line's dial plan.
• If non-administrator users are given access to the Reports » Call history menu in their role, they are now only shown calls made by telephones and remote access accounts that they own.
• Sound file downloads use "Content-Disposition: attachment" rather than "Content-Disposition: inline".
• As always, some SOAP API functions have changed. Please see /opt/enswitch/current/doc/api_changes.txt for a list.
