We’re happy to share with you the many firsts in this release: the 1st fully stacked 64-bit ARM Sailfish OS, that you can download and flash onto the Sony Xperia 10 II, which is also the first Sailfish device with AOSP-10 HW adaptation. The commercial Sailfish X package also introduces the 64-bit Android App Support for Xperia 10 II.
Sailfish OS Kvarken 4.1.0 has now moved from early access to full release. That means the early access bugs have been ironed out, but also that the paid-for additions (particularly Android App Support) are also now available for it.
While the headline changes in 4.1.0 is the shift to full 64-bit ARM and support for the new hardware, it also introduces many other improvements, including to location data support, VPN support, audio recording, browser, calendar sync and contact sync, amongst other things.
