| 16 | +Fix a potential memory denial of service in the :mod:`http.client` module. |
| 17 | +When connecting to a malicious server, it could cause an arbitrary amount of |
| 18 | +memory to be allocated. This could have led to symptoms including a |
| 19 | +:exc:`MemoryError`, swapping, out of memory (OOM) killed processes or |
| 20 | +containers, or even system crashes. |

| 32 | +symptoms including a :exc:`MemoryError`, swapping, out of memory (OOM) |

| 42 | +Revert changes to the undocumented :class:`!re.Scanner` class. Capturing |
| 43 | +groups are still allowed for backward compatibility, although using them can |
| 44 | +lead to incorrect result. They will be forbidden in future Python versions. |

|
| 53 | +The resource tracker in the :mod:`multiprocessing` module now uses the |
| 54 | +original communication protocol, as in Python 3.14.0 and below, by default. |
| 55 | +This avoids issues with upgrading Python while it is running. (Note that |
| 56 | +such 'in-place' upgrades are not tested.) The tracker remains compatible |
| 57 | +with subprocesses that use new protocol (that is, subprocesses using Python |
| 58 | +3.13.10, 3.14.1 and 3.15). |
