## [0.1.0] - 2026-10-06
### Added
- Initial release: patch coverage for git diffs, as the `patchcov` command and
library.
- `patchcov diff` attributes an lcov, llvm-cov JSON, Cobertura, JaCoCo or Go
coverprofile report to a git diff and reports patch coverage, the uncovered new
lines, per-file project deltas and indirect changes, as markdown, YAML or JSON,
with `--fail-under-patch` and `--fail-under-lines` gates.
- `patchcov merge` merges the per-shard reports of a sharded run into one lcov
file.
- `patchcov lint-markers` checks the syntax of `patchcov: coverage ignore` and
`tolerate` source markers.
- Repository settings live in `.patchcov/config.yaml`; `PATCHCOV_CONFIG_DIR` and
`--config-dir` override discovery.
The code was extracted, with its history, from `omni-dev coverage`. It is a clean
break: the config directory, environment variable and marker introducer are
patchcov's own, and nothing reads `.omni-dev/` or `OMNI_DEV_*`.
