No objections here.

   Update: today s the day I announced as the earliest possible time
   to do this, and no one has opposed.
   For closure, I initially planned to add support for Python 3.10
   *before* dropping 3.6 but alas it turns out that our dependencies
   are not ready yet.
   Most notably matplotlib is still due for a release with Python
   3.10 wheels, and there s not much we can do before that happens.
   I don t think now that it should stop us from dropping 3.6 anyway.
   Any objections ?

       Dear yt dev team,

       As was previously mentioned in yt 4.0.0's release notes,
       we're currently
       planning to drop support for Python 3.6 in our next feature
       release (4.1.0)
       I propose that this change be performed on the dev branch of
       yt *by late*
       *October this year*, but *not earlier than October the 20th.*

       As was discussed on Slack, I would like to send an official
       announcement
       to yt-users@python.org <mailto:yt-users@python.org>, but
       I ll leave open to discussion for a week first, or
       as long as necessary for the discussion to resolve happily.


       Here's the PR to drop Python 3.6
       https://github.com/yt-project/yt/pull/2917
       <https://github.com/yt-project/yt/pull/2917>
       Please take minute to either?request changes, discuss and/or
       approve it.



       *_Nice implications_*

       This means we'll soon be able to use Python 3.7+ only syntax
       and features.
       Here are the two key highlights that I personally think are
       most impactful for yt:

         * ?`from __future__ import annotations` can be used to
           leverage modern Python annotations features from more
           recent versions (as late as 3.11 !) This will be
           extremely useful to improve typing in yt, and in support
           to YTEP 0038 https://github.com/yt-project/ytep/pull/17
           <https://github.com/yt-project/ytep/pull/17>?Here's a
           gist with some showcase examples of how this __future__
           import helps simplifying typed code
           https://gist.github.com/neutrinoceros/0eaa046a00689254dee0738c65c9bdfc
           <https://gist.github.com/neutrinoceros/0eaa046a00689254dee0738c65c9bdfc>
         * the `dataclasses` module becomes available
           https://docs.python.org/3/whatsnew/3.7.html#whatsnew37-pep557
           <https://docs.python.org/3/whatsnew/3.7.html#whatsnew37-pep557>


       See the detailed "what's new" note from Python 3.7.0 for
       more https://docs.python.org/3/whatsnew/3.7.html
       <https://docs.python.org/3/whatsnew/3.7.html>


       *_Additional notes_*
       *_
       _*

         * Python 3.6 is 5 years old and will be EOL (end of life)
           by December https://www.python.org/dev/peps/pep-0494/
           <https://www.python.org/dev/peps/pep-0494/>
         * Numpy dropped support for Python 3.6 in numpy 1.20.0,
           released in January 2021
           https://github.com/numpy/numpy/releases/tag/v1.20.0
           <https://github.com/numpy/numpy/releases/tag/v1.20.0>
         * Matplotlib dropped support fot Python 3.6 in matplotlib
           3.4.0, released in March 2021
           https://github.com/matplotlib/matplotlib/commit/f9907b49f9d00c03cf014a25d057d0d09d43d8cf
           <https://github.com/matplotlib/matplotlib/commit/f9907b49f9d00c03cf014a25d057d0d09d43d8cf>
         * Python 3.10 will be officially released early October
           https://www.python.org/dev/peps/pep-0619/
           <https://www.python.org/dev/peps/pep-0619/>
         * Adding support for 3.10 should be a breeze^{TM}: we've
           been running a subset of our test suite against it (+
           future versions of matplotlib and numpy) for a couple
           months, so the expected most important bottleneck for us
           will depend on when numpy and matplotlib are able to
           publish wheels for 3.10
         * The plan is to first add support to 3.10 and *then* drop
           3.6.
         * This is in agreement with NEP 29, which was coauthored
           by our own release manager, Madicken Munk
           https://numpy.org/neps/nep-0029-deprecation_policy.html
           <https://numpy.org/neps/nep-0029-deprecation_policy.html>
         * ?Various 3.7+ idioms will now be continuously enforced
           with pyupgrade https://github.com/asottile/pyupgrade
           <https://github.com/asottile/pyupgrade>?which is already
           part of our pre-commit toolbelt.



       Cheers, and have a great week
