Gammu1.27.95 has been just released. Yet another bugfix release, still quite far from calling this stable. The major change here is renaming Port configuration directive to Device as it is easily understand (the old option will still work for several years).
Full list of changes:
Support for getting packet network state (bug #1220).
Fix parsing of AT replies from Nokia 2730 (bug #1224).
Nokia E61 needs encoded USSD requests (bug #1228).
Rename Port configuration directive to Device.
Try to reconnect after lost connection to MySQL error.
