Sailfish OS 3.0.1 has been released. From the release notes:
Sipoonkorpi is mainly a bug fixing update, bringing in just a few new features. We’ve added Bulgarian language support and improved the handling of email folders. You can now create light ambiences, and respond to meeting invitations through Exchange and Google. We’ve also tuned up SD card encryption and protected critical Top Menu toggles with the security code.
It’s available for Jolla devices and the Xperia X and XA2.
