Version 7.13.5 — 2026-03-17

• Fix: issue 2138_ describes a memory leak that happened when repeatedly using the Coverage API with in-memory data. This is now fixed.

• Fix: the markdown-formatted coverage report didn't fully escape special characters in file paths (issue 2141). This would be very unlikely to cause a problem, but now it's done properly, thanks to Ellie Ayla <pull 2142_>.

• Fix: the C extension wouldn't build on VS2019, but now it does (issue 2145_).

Version 7.13.4 — 2026-02-09

• Fix: the third-party code fix in 7.13.3 required examining the parent directories where coverage was run. In the unusual situation that one of the parent directories is unreadable, a PermissionError would occur, as described in issue 2129_. This is now fixed.

• Fix: in test suites that change sys.path, coverage.py could fail with "RuntimeError: Set changed size during iteration" as described and fixed in pull 2130_. Thanks, Noah Fatsi.

• We now publish ppc64le wheels, thanks to Pankhudi Jain <pull 2121_>_.

Version 7.13.3 — 2026-02-03

• Fix: in some situations, third-party code was measured when it shouldn't have been, slowing down test execution. This happened with layered virtual environments such as uv sometimes makes. The problem is fixed, closing issue 2082_. Now any directory on sys.path that is inside a virtualenv is considered third-party code.
