Increased minimum versions for dependencies
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Some minimum supported versions of dependencies were updated (:issue:`33718`).
If installed, we now require:

+-----------------+-----------------+----------+---------+
| Package | Minimum Version | Required | Changed |
+=================+=================+==========+=========+
| numpy | 1.15.4 | X | X |
+-----------------+-----------------+----------+---------+
| pytz | 2015.4 | X | |
+-----------------+-----------------+----------+---------+
| python-dateutil | 2.6.1 | X | |
+-----------------+-----------------+----------+---------+
| bottleneck | 1.2.1 | | |
+-----------------+-----------------+----------+---------+
| numexpr | 2.6.2 | | |
+-----------------+-----------------+----------+---------+
| pytest (dev) | 4.0.2 | | |
+-----------------+-----------------+----------+---------+

For `optional libraries <https://dev.pandas.io/docs/install.html#dependencies>`_ the general recommendation is to use the latest version.
The following table lists the lowest version per library that is currently being tested throughout the development of pandas.
Optional libraries below the lowest tested version may still work, but are not considered supported.

+-----------------+-----------------+---------+
| Package | Minimum Version | Changed |
+=================+=================+=========+
| beautifulsoup4 | 4.6.0 | |
+-----------------+-----------------+---------+

Shouldn't that be "numpy>=1.15.4"? I had issues installing pandas from source with numpy 1.18.5 installed.
Should I create a ticket for that?

I don't believe so. We build with the oldest supported NumPy that is compatible with the version of NumPy.

I had issues installing pandas from source with numpy 1.18.5 installed.

This also doesn't quite make sense. The idea behind pyproject.toml is to isolate the build environment. It shouldn't matter what version of NumPy was used to build pandas with, as long as it's binary compatible (IIUC).

Ok, ignore my comment if that is how you make sure that your build with the oldest supported version.

In my case I have numpy 1.18.5 installed and I want to use it to build pandas from source. However, it complains that the build requirements are note met.

However, were you using python 3.8? There was an issue with us not having a line for py38. #34667

No, 3.7.

Ok, I think I didn't quite understood how build isolation works. Thanks for your quick relies!
