That was Vim 8.2.4106.
Today at work I updated my plugin and got an error, because
getcharstr doesn't exist. This is Vim 8.2.1123.
getcharstr introduced? I had no luck in
:help vim8, nor by
grepping the repository (because I was
grepping my fork which was not up-to-date, silly me).
Besides, is this information even available in a Vim installation (in the form of release notes or something)? Or how should I find it from the repository?
