用车汽车身上那些“疤痕”怎么修复完美如初？
百度 而校方的苦衷似乎也情有可原——一位从教20多年的老校长说，校园非理性现象尤其是校园欺凌的发生，大多发生在课后，老师看不见、家长管不着、门卫顾不上。The main branch is currently the future Python 3.15, and is the only
branch that accepts new features. The latest release for each Python
version can be found on the download page.
(See below for a chart with older versions. Another useful visualization is endoflife.date/python.)

Status key?
Python releases go through five phases, as described in PEP 602. Release managers can adjust specific dates as needed.
- feature:
Before the first beta, the next full release can accept new features, bug fixes, and security fixes.
- prerelease:
After the first beta, no new features can go in, but feature fixes (including significant changes to new features), bug fixes, and security fixes are accepted for the upcoming feature release.
- bugfix:
Once a version has been fully released, bug fixes and security fixes are accepted. New binaries are built and released roughly every two months. This phase is also called maintenance mode or stable release.
- security:
After two years (18 months for versions before 3.13), only security fixes are accepted and no more binaries are released. New source-only versions can be released as needed.
- end-of-life:
Five years after a release, support ends. The release cycle is frozen; no further changes are allowed.
See also the Development cycle page for more information about branches and backporting.
