I just installed the bintar 10.11.7 on Ubuntu 23.10 and the mysql CLI binary still requires libncurses5. The release notes also do not mention a switch to libncurses6.

Thank you for reporting this. Trixie is unstable and Ubuntu is based on Debian 12 which is stable they are more conservative on now a days on Ubuntu than on Debian to break things.

Does it automatically solve problems or does it need some extra work?

As I wrote in MDEV-26265, I install the libncurses5 (and libtinfo5) from Ubuntu 23.04's deb files. Then it works. But that's no long-term solution.

Sorry I'm little bit confused. Is there still some parts of tarbin 10.11.7 still linked against ncurses5 and some are ncurses6?

This is what happens:

Without installed libncurses5 libs, the "mysql" binary (from 10.11.7) complains about them not being there. Installing the libraries makes the error go away. So, yes, to me it seems that at least the "mysql" binary is still linked against libncurses5.
