Installing Kallithea 0.7.0

[kallithea at simple-test-bed.de]

Hello,

I currently try to install the current kallithea 0.7.0 with
>> pip install kallithea <<
in a virtualenv.

Unfortunately the installation process stops when it comes to the installation of FormEncode.
I my environment I have Python 3.11.2 and Formencode 2.1.1 installed (Debian Bookworm)

Unfortunately it looks like, that Kallithea is requesting a very old FormEncode<1.4,>=1.3.1
and this is not possible, as my Python is to new for this old version of FormEncode.

The error message is:
---------------------
>Collecting FormEncode<1.4,>=1.3.1
>  Using cached FormEncode-1.3.1.tar.gz (197 kB)

How can I overcome this problem?

Thanks for any useful hints.
