Version 7.10.0 — 2025-07-24

• A new configuration option: ":ref:config_run_patch" specifies named patches to work around some limitations in coverage measurement. These patches are available:

  • patch = _exit lets coverage save its data even when :func:os._exit() <python:os._exit> is used to abruptly end the process. This closes long-standing issue 310_ as well as its duplicates: issue 312, issue 1673, issue 1845, and issue 1941.

  • patch = subprocess measures coverage in Python subprocesses created with :mod:subprocess, :func:os.system, or one of the :func:execv <python:os.execl> or :func:spawnv <python:os.spawnl> family of functions. Closes old issue 367_ and duplicate issue 378_.

  • patch = execv adjusts the :func:execv <python:os.execl> family of functions to save coverage data before ending the current program and starting the next. Not available on Windows. Closes issue 43_ after 15 years!

• The HTML report now dimly colors subsequent lines in multi-line statements. They used to have no color. This gives a better indication of the amount of code missing in the report. Closes issue 1308_.

• Two new exclusion patterns are part of the defaults: ... is automatically excluded as a line and if TYPE_CHECKING: is excluded as a branch. Closes issue 831_.

• A new command-line option: --save-signal=USR1 specifies a signal that coverage.py will listen for. When the signal is sent, the coverage data will be saved. This makes it possible to save data from within long-running processes. Thanks, Arkady Gilinsky <pull 1998_>_.

• A new configuration option: ":ref:config_report_partial_also" is a list of regexes to add as pragmas for partial branches. This parallels the ":ref:config_report_exclude_also" setting for adding line exclusion patterns.

• A few file path configuration settings didn't allow for tilde expansion: :ref:config_json_output, :ref:config_lcov_output and :ref:config_run_debug_file. This is now fixed.

• Wheels are included for 3.14 now that 3.14 rc1 is available.

• We no longer ship a PyPy-specific wheel. PyPy will install the pure-Python wheel. Closes issue 2001_.

• In the very unusual situation of not having a current frame, coverage no
