"sage-optional" uses PyPI to determine available versions of pip packages
(see
https://doc.sagemath.org/html/en/developer/packaging.html#package-source-types
for the definition).
The ore-algebra project, unfortunately, does not make proper releases; the
Sage package is keyed to a particular commit in the project's github.
$ cat build/pkgs/ore_algebra/requirements.txt
git+https://github.com/mkauers/ore_algebra@6826ac49b4cdf66a563449aced21a2fd1fd085c9#egg=ore_algebra
You can help by convincing the project maintainers to follow the best
practices for Python packages: making releases and publishing them on PyPI.

Our jupyterlab package, added in https://trac.sagemath.org/ticket/26059, is
a pip package. It uses the following version specification:
$ cat build/pkgs/jupyterlab/requirements.txt
jupyterlab ~= 2.2.5
I would hope that in the Sage 9.4 series, we can upgrade
ipython/jupyter/jupyterlab. There is already a ticket for this
task: https://trac.sagemath.org/ticket/31280 – help is welcome.
