Jolla decided to change the RPM format (see discussion over here Q: 4.5 will switch RPM compression. What does that mean for existing RPMs?)
A direct consequence is that RPMs build in a SFOS 4.5 toolkit can no longer be installed on older SFOS versions.
Jolla only writes a few lines in the changelog and that’s it, leaving all further consequences up to the developers.
But what had Jolla in mind when considering this change?
- We just abruptly break compatibility with older SFOS versions
- We will release an new rpm for other SFOS versions that will support the new compression
- We want you to add settings to spec files so only the old compression is used
- We want you to avoid the new toolkit as much as possilbe
- Something else, namely …
Why not write a ‘blog/Sailfish Community News’ about this, explaining what was done and why and how to deal with it (just like the sailjail change)? Flypig did a great job filling the gap between Jolla and the users/developers, but now that he has left the company I am afraid this gap will return.
