### Release Notes

<summary>mitsuhiko/insta (insta)</summary>

###
[`v1.44.2`](https://redirect.github.com/mitsuhiko/insta/blob/HEAD/CHANGELOG.md#1442)

[Compare
Source](https://redirect.github.com/mitsuhiko/insta/compare/1.44.1...1.44.2)

- Fix a rare backward compatibility issue where inline snapshots using
an uncommon legacy format (single-line content stored in multiline raw
strings) could fail to match after 1.44.0.
[#&#8203;830](https://redirect.github.com/mitsuhiko/insta/issues/830)
- Handle merge conflicts in snapshot files gracefully. When a snapshot
file contains git merge conflict markers, insta now detects them and
treats the snapshot as missing, allowing tests to continue and create a
new pending snapshot for review.
[#&#8203;829](https://redirect.github.com/mitsuhiko/insta/issues/829)
- Skip nextest\_doctest tests when cargo-nextest is not installed.
[#&#8203;826](https://redirect.github.com/mitsuhiko/insta/issues/826)
- Fix functional tests failing under nextest due to inherited
`NEXTEST_RUN_ID` environment variable.
[#&#8203;824](https://redirect.github.com/mitsuhiko/insta/issues/824)
