The list isn't particularly surprising but the proposed changes mailed out today on fedora-devel are for:
- Glibc 2.23 for Fedora 24. Basically, updating against the new version of glibc. Fedora Rawhide has already been tracking v2.23 development.
- Related to glibc, librtkaio would be dropped. More than one decade ago rtkaio was added for a POSIX realtime API that used the Linux kernel's AIO support. However, after all this time, there are no major users using rtkaio.
- GNOME 3.20 for Fedora 24... No surprise at all. GNOME 3.20 will have all the latest desktop goodies in time for Fedora 24 shipping.
- Support for graphical system upgrades. These Fedora 24 system upgrades would be done through the GNOME Software package manager / app store UI.
These changes are on top of a lot of other changes coming for Fedora 24. Fedora 24 is currently scheduled to be released in early June.
