Application SDK Early Access

From SailfishOS Documentation

Early Access SDK

Sailfish OS SDK Early Access releases will go in sync with the early access releases of the Sailfish OS. Generally these releases will be available about a week earlier than the official public release. This allows developers to test and refine their apps before the public release.

Please, remember, that during the early access time the Early Access SDK should not be used for submitting apps to the Jolla Harbour. For that purpose, the latest public SDK can be found from the Application SDK page. There's also other SDK related information available on the same page.

Release Notes

SDK version 1710 (2.1.3)

Today (Nov 8th) at 10:00 UTC we have published new installers and repositories of the Sailfish OS SDK. This SDK release is called 1710 and it matches Jolla Release 2.1.3. This release was made available to all SDK users on Nov 17th.

Please, read the following notes about the Early Access SDK:

The installers for this release of the SDK are available at If you have an older beta release of the SDK, you should see an update notification in the Sailfish OS IDE.

SDK content matches Jolla Release (Kymijoki). Please see below for detailed information of the changes.

A couple of things you should be aware of:

  • As before, in this update the build engine, emulator and targets are reinstalled so you will lose all changes you may have made in those - However, if your application packaging is done correctly, rebuilding your projects should reinstall the packages you have been using.
  • Any customization done to SDK (adding new package repositories, adding custom targets, additional source paths) will be removed during the installation process so make your own backup of those before starting the update.
  • If you import existing projects made with a previous version of the Sailfish OS SDK, make sure to select the correct kit in the project configuration step. Both ARM and i486 kits are available.
  • Package repository contents have been updated and consequently using a previous SDK version with these package repositories is not supported.
  • For more information, please see the Application SDK known issues list.

      • This will allow users to build packages for older Sailfish OS releases in a single SDK (e.g. for both 2.1.4 and 2.1.3 in the future)
