The ncurses upstream has released a first 6.0 version few months ago. The default ABI version has changed to 6, which enables some extensions to allow more colors, mouse wheel, etc. The ABI version 5 is still supported and can be selected with a configure option. We should switch to the new ABI, but we will probably want to provide the old ABI 5 libs even when all Fedora ncurses applications are rebuilt with the new ABI to not break 3rd party packages. Dependency on libncurses.so.5 or libtinfo.so.5 is pretty common. As for updating the ncurses package, my current plan is to build the libs in both ABIs (so there are four builds total with the wide and narrow versions), use the ncurses-libs subpackage for the new ABI 6 libs and create a new subpackage for ABI 5 libs. What would be a good name of the subpackage? ncurses-libs5, ncurses5-libs, compat-ncurses5, or something else?
According to http://www.gnu.org/software/ncurses/ the new ABI should include symbol versioning, which would hopefully avoid the need for a repeat of this pain in the future, but as far as I can see none of the symbols in the current F23 build are versioned?
