Hello,
It is a common practice to specify the major and minor version in the .python-version file. For example, many of my repos have 3.11 instead of 3.11.14 in that file. This works fine for pyenv: it will use the latest version of 3.11 in that case.
Unfortunately this doesn't work with pyenv-mode: it will always report that "version 3.11 is not installed"
