Contrary to what the version numbering would suggest, this is a significant update with many new features and bug fixes. See the release notes for full details, but here are some hightlights for Asterisk users:

- Context-sensitive softkeys. Softkeys can now be configured for each of the following call states: idle, incoming, outgoing and connected
- Speed dial using the BLF key
- Per-line outbound proxy
- Use the Icom key to make intercom calls
- Further XML enhancements
- Voice quality (transmit level) issues resolved
- Keypad now continues to work when a second incoming call appears

And much more.
