The current upstream release is 1.5.1.
I am aware of the 1.5.x series but unfortunately, the version bump will not happen any time soon. python-rtmidi upstream has switched to a build back-end, mesonpep517, that is neither supported by distutils-r1.eclass nor even packaged in Gentoo - and given the latter hasn't seen any new releases for over 2 years or any repo activity for over 1 year, I am not exactly keen on packaging it. In my copious spare time, I am going to try and make it use meson-python instead.
