Among the new major new features and changes so far:
- PEP 623 -- Deprecate and prepare for the removal of the wstr member in PyUnicodeObject.
- PEP 604 -- Allow writing union types as X | Y
- PEP 612 -- Parameter Specification Variables
- PEP 626 -- Precise line numbers for debugging and other tools.
- PEP 618 -- Add Optional Length-Checking To zip.
- bpo-12782: Parenthesized context managers are now officially allowed.
- PEP 632 -- Deprecate distutils module.
- PEP 613 -- Explicit Type Aliases
- PEP 634 -- Structural Pattern Matching: Specification
- PEP 635 -- Structural Pattern Matching: Motivation and Rationale
- PEP 636 -- Structural Pattern Matching: Tutorial
- PEP 644 -- Require OpenSSL 1.1.1 or newer
- PEP 624 -- Remove Py_UNICODE encoder APIs
- PEP 597 -- Add optional EncodingWarning
from __future__ import annotations (PEP 563) used to be on this list
in previous pre-releases but it has been postponed to Python 3.11 due to some compatibility concerns. You can read the Steering Council communication about it here to learn more.

And now for something completely different
In quantum mechanics, the uncertainty principle (also known as Heisenberg's uncertainty principle) is any of a variety of mathematical inequalities asserting a fundamental limit to the accuracy with which the values for certain pairs of physical quantities of a particle, such as position and momentum or the time and the energy can be predicted from initial conditions. Such variable pairs are known as complementary variables or canonically conjugate variables; and, depending on interpretation, the uncertainty principle limits to what extent such conjugate properties maintain their approximate meaning, as the mathematical framework of quantum physics does not support the notion of simultaneously well-defined conjugate properties expressed by a single value. The uncertainty principle implies that it is in general not possible to predict the value of a quantity with arbitrary certainty, even if all initial conditions are specified.
