-We ***strongly encourage*** maintainers of third-party Python projects to ***test with 3.15*** during the beta phase and report issues found to [the Python bug tracker](https://github.com/python/cpython/issues) as soon as possible. While the release is planned to be feature-complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2026-08-04). Our goal is to have ***no ABI changes*** after beta 4 and as few code changes as possible after the first release candidate. To achieve that, it will be ***extremely important*** to get as much exposure for 3.15 as possible during the beta phase.
