(Some removals present in alpha 1 were reverted in alpha 2, as the removals were deemed too disruptive at this time.)<br> New deprecations, most of which are scheduled for removal from Python 3.15 or 3.16.<br> (Hey, <strong>fellow core developer</strong>, if a feature you find important is missing from this list, let Thomas know.)</p> <p>For more details on the changes to Python 3.13, see What's new in Python 3.13. The next pre-release of Python 3.13 will be 3.13.0b3, currently scheduled for 2024-06-25.</p> YashShreshthaRaj404
