Changelog
### 7.5.4
```
--------------------------
- If you attempt to combine statement coverage data with branch coverage data,
coverage.py used to fail with the message "Can't combine arc data with line
data" or its reverse, "Can't combine line data with arc data." These
messages used internal terminology, making it hard for people to understand
the problem. They are now changed to mention "branch coverage data" and
"statement coverage data."
- Fixed a minor branch coverage problem with wildcard match/case cases using
names or guard clauses.
- Started testing on 3.13 free-threading (nogil) builds of Python. I'm not
claiming full support yet. Closes `issue 1799`_.

```
### 7.5.3
```
--------------------------
- Performance improvements for combining data files, especially when measuring
line coverage. A few different quadratic behaviors were eliminated. In one
extreme case of combining 700+ data files, the time dropped from more than
three hours to seven minutes. Thanks for Kraken Tech for funding the fix.
- Performance improvements for generating HTML reports, with a side benefit of
reducing memory use, closing `issue 1791`_. Thanks to Daniel Diniz for
helping to diagnose the problem.

```
### 7.5.2
```
--------------------------
- Fix: nested matches of exclude patterns could exclude too much code, as
reported in `issue 1779`_. This is now fixed.
- Changed: previously, coverage.py would consider a module docstring to be an
executable statement if it appeared after line 1 in the file, but not
executable if it was the first line. Now module docstrings are never counted
as executable statements. This can change coverage.py's count of the number
of statements in a file, which can slightly change the coverage percentage
reported.
- In the HTML report, the filter term and "hide covered" checkbox settings are
remembered between viewings, thanks to `Daniel Diniz <pull 1776_>`_.
- Python 3.13.0b1 is supported.
- Fix: parsing error handling is improved to ensure bizarre source files are
handled gracefully, and to unblock oss-fuzz fuzzing, thanks to `Liam DeVoe
<pull 1788_>`_. Closes `issue 1787`_.
