Fourth generation of Sailfish OS is here!

We’ve come a long way, since Sailfish OS was first introduced in 2013. Now as we enter the 4th generation with Sailfish OS, the secure platform for trusted mobile solutions, we can proudly say that our product is in great shape and ready to expand to new frontiers!  After Sailfish 3 was launched many big developments have happened that have have impacted Jolla, Sailfish OS, our partners with us, and all the daily Sailfish users.

To name a few:

  • We have delivered over 5,000 improvements and fixes to the OS since Sailfish 3. In particular, our emphasis has been on various security features to ease corporate level deployments but which are also beneficial for all privacy-caring users
  • The EU GDPR went into effect, and we’re proud to have been 100 % compliant from day 1 (and even before that)
  • Full-scale Sailfish X ports were developed for Sony Xperia XA2 and Xperia 10 together with the great Sailfish community
  • Our unique Android App Support for Linux platforms was updated to support Android 9 apps, and the support for Android 10 apps is already nicely on the way
  • A new Sailfish OS Forum was created, and we’ve been happy to see many new members join the discussions in the much more lively forum – thanks for all the encouraging feedback!
  • Long-term collaboration with OMP deploying Aurora OS in Russia has delivered tons of open source contributions to the OS

On a high-level Sailfish 4 includes several security and functionality updates, the long-awaited browser update, redesigned daily usage flow of key applications, as well as a rebooted developer experience. In particular we’re proud to boast full-scale OS-level Mobile Device Management (MDM) to enable easy and manageable end-to-end trusted corporate and governmental sector deployments.

The first Sailfish 4 software release, Koli, is today made available to all Sailfish users. You’re welcome to read more details from the Koli blog post, which our software engineer David Llewellyn-Jones has crafted.To celebrate this milestone Sailfish 4 release, we’ve also just published a major update to the Sailfish OS website to show better and more visually what this great alternative OS is all about – be sure to check out that as well!

    great to hear about a new update – once we will see the magical VoLTE/VoWifi support, too… 😉

    slowly but steadily it will be a necessity in corporate domain as well…

    With the newest update, users still cannot bluetooth mp3s. Like on Sailfish III, VPNs still don’t work on my device…or perhaps I don’t know how to configure them. Would it be possible for Jolla to accept payments in Bitcoin? PayPal wants to know everything about its user and I like anonymity. I ask because my Travelex Money Card no longer works in my region all thanks to the COVID 19 scamdemic/lockdown.

    I wish the full refund for the tablet backers was here.

    Still no word even after 6!! years Jolla has not been able to close this chapter of their history.

    So yes Jolla has come a long way, and has still a long way to go before they can continue as a trustworthy company.

    Fairy tales and lies is what they sell so far.
    Make amends Jolla ! Pay your tablet the promised full refund !

      Can you imagine all the things you could buy if you’d spent even half the time you spent over the years complaining about not getting the second half of your refund working?

      I get it, you’re pissed that you didn’t get a full refund when the tablet project went wrong for reasons outside of Jolla’s control, but moaning about it in the comments to every single Jolla blog post for years on end is more than just excessive.
