Description of problem: 1.2.0 final of speex is released. Actually, it has been since December 2016. Fedora is still shipping 1.2rc from December 2014. Additional info: Alas, speex is sort of "obsoleted by opus", but as it's still being shipped, and even being maintained, why not have it up to date. The changes from 1.2rc to 1.2.0 are small, but not restricted to cosmetics (AFAICT).
Thanks for the report. In rawhide there be should be now speex-1.2.0-1.fc29.
