<h2>Version 2.14.0</h2>
<h2>Upcoming deprecation</h2>
<ul>
<li>This version, Babel 2.14, is the last version of Babel to support
Python 3.7. Babel 2.15 will require Python 3.8 or newer.
We had previously announced Babel 2.13 to have been the last version to
support Python 3.7, but being able to use CLDR 43 with Python 3.7 was
deemed important enough to keep supporting the EOL Python version for
one more release.</li>
</ul>
<h2>Possibly backwards incompatible changes</h2>
<ul>
<li>Locale.number_symbols will now have first-level keys for each
numbering system. Since the implicit default numbering system still is
&quot;latn&quot;, what had previously been e.g.
Locale.number_symbols['decimal'] is now
Locale.number_symbols['latn']['decimal'].</li>
<li>Babel no longer directly depends on either distutils or setuptools;
if you had been using the Babel setuptools command extensions, you would
need to explicitly depend on setuptools – though given you're running
setup.py you probably already do.</li>
</ul>
