Actually just found that this install time dependency cen be dropped

[tkloczko@devel-g2v sphinx-tabs-3.4.0]$ grep -r jinja2
setup.py:    install_requires=["sphinx>=2,<6", "pygments", "docutils~=0.17.0", "jinja2<3.1.0"],

[foster999]

This was added in #164 because later versions of jinja2 seem to be incompatible with older versions of sphinx. Running the tests without that dependency specified shows that sphinx imports a depreciated jinja2 object.

We could make the requirement more specific if we can identify when the breaking change was included? Otherwise, this might be an issue for sphinx to support the latest versions of jinja2?

[foster999]

So it looks like this has already been addressed in the latest versions of sphinx. I think our solution would be to follow sphinx and only officially support their latest version, because it would be too much faff to manage the dependencies for older sphinx versions

There's a comment on there suggesting that sphinx should pin the jinja2 version in older sphinx versions, but lack of this causes the issue here

As you see sphinx has now jinnja2 on list of its dependencies.

[foster999]

The issue here was due to jinja2 not being listed in their dependencies in older sphinx versions that we were trying to support. But I think this has highlighted that we don't need to try to support older versions, so thanks :)

[kloczek]

IIRC it is possible to make conditional dependencies. In case of sphins 5.x clearly that dependency is redundant.

[foster999]

Jinja2 version no longer pinned from v3.4.1 👍🏻

[kloczek]

Thank you. Just added that PR to my build procedure and so far all look good 👍
