Release Notes

mitsuhiko/insta (insta)

v1.45.0

• Add external diff tool support via INSTA_DIFF_TOOL environment variable. When set, insta uses the specified tool (e.g., delta, difftastic) to display snapshot diffs instead of the built-in diff. The tool is invoked as <tool> <old_file> <new_file>. #​844
• Add test.disable_nextest_doctest config option to insta.yaml, allowing users to silence the nextest doctest warning via config instead of passing --dnd every time. #​842
• Skip non-insta snapshot files in unreferenced detection. Projects using both insta and other snapshot tools (like vitest or jest) can now use --unreferenced=reject without false positives on .snap files from other tools. #​846
• Collect warnings from tests for display after run. Ensures deprecation warnings are visible even when nextest suppresses stdout/stderr from passing tests. #​840
• Update TOML serialization to be up-to-date and backwards-compatible. #​834
• Support clippy::needless_raw_strings lint by only using raw strings when content contains backslashes or quotes. #​828
