Description
Documentation for v3.14 - 3.15 migration PR: feat(profiling): support Python 3.15 (#17294).
Changes
docs/contributing-profiling-new-cpython.rst: new maintainer runbook for adding support for a new CPython minor version across the full Continuous Profiler stack (Echion/stack, asyncio, lock, memory/heap). Covers preparation, discovery, implementation checklist, and validation. References PR feat(profiling): [2/n][NO_MERGE] support Python 3.15 for profiling #17294 as the canonical 3.15 example.docs/cpython-diffs/analysis_314_to_315.md: reference analysis of every 3.14→3.15 ABI change relevant to echion — per-item impact notes, completed checklist, and cross-references to the guards we added. Useful when doing the 3.16 port.docs/contributing.rst: adds a link to the new runbook in the contributing index..claude/skills/compare-cpython-versions/SKILL.md: adds explicit enum-renumbering checklist item (silent correctness bug, not a compile error) and thestatic_assert/-Wswitchcontract pattern as the recommended approach for catching future CPython regressions at build time.
