Jolla has released its latest big update for Sailfish today, the fourth big update since the first release early December. It's got a whole boatload of improvements and fixes - the most important of which, to me at least, are two-way Google Calendar sync and landscape mode for email, messages, and notes. I'm also hoping for actually working sync for Gmail (read my review for more on that). Other improvements include lots of UI fixes, lots of new settings for the camera, improved Exchange ActiveSync support, and lots more.
The update is rolling out to all Jolla phones as we speak.
