Why Fedora 26 comes with old Scala version?

[Oliver Ruebenacker]

     Hello,

  I'm just upgrading a laptop from Fedora 25 to 26. The upgrade process
just announced it will downgrade Scala from 2.12 to 2.10. Why Fedora 26
comes with a very old Scala version, when the latest is Scala 2.12.4 and it
is available as RPM <http://www.scala-lang.org/download/>?

  Thanks!

     Best, Oliver

I assume you installed that 2.12 version of Scala yourself, it's not 
from Fedora.

Here's some info on why it hasn't been updated yet:

  Yes, it is not from Fedora. So, why Fedora doesn't provide Scala 2.12?
Thanks!

Did you look at the bugzilla link I sent in the previous email?

Did you bother reading the URL that Sam posted?

	https://bugzilla.redhat.com/show_bug.cgi?id=1080923

You'll see why it's not in there. In a nutshell, Scala 2.11 and later
are not binary-compatible with 2.10 so all the packages that depend
on Scala will break. The maintainer of Scala has no control over those
other packages.

At least that's how I read it.
