Python 3.10 is still in development. This releasee, 3.10.0a3 is the second of six planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2021-05-03) and, if necessary, may be modified or deleted up until the release candidate phase (2021-10-04). Please keep in mind that this is a preview release and its use is not recommended for production environments.

- PEP 623 -- Remove wstr from Unicode
- PEP 604 -- Allow writing union types as X | Y
- PEP 612 -- Parameter Specification Variables
- PEP 626 -- Precise line numbers for debugging and other tools.
from __future__ import annotations(PEP 563) is now the default.
PEP 618 -- Add Optional Length-Checking To zip.
