Python 3.13 will receive full bugfix support until approximately , followed by three additional years of security updates. PEP 719 – Python 3.13 Release Schedule
| Stakeholder | Impact of 3.13.1 Release Timing | |-------------|--------------------------------| | | A release in late April 2026 gives a ~6‑month window after 3.13.0 for organizations to test and adopt the new interpreter before the first official security‑fix release. | | Package Maintainers (PyPI) | Need to rebuild wheels for any compiled extensions targeting the new ABI (PEP 656). Early access to the 3.13.1 source tarball via the pre‑release tag will help avoid “broken‑wheel” regressions. | | Tooling Vendors | IDEs, linters, and static analysers should schedule a compatibility check in the April–May 2026 sprint. | | Researchers | Benchmark suites (e.g., pyperformance) should include 3.13.1 to capture any micro‑optimisations back‑ported from 3.12.x. | python 3.13.1 release date news
