# Changelog
## [0.2.0.0] - 2026-10-01
### Removed
* `runFoundFailure`. It existed only because a timed-out mutation could
abort a fail-fast run that the driver then reported as finished, and a
timeout no longer stops a run at all.
## [0.1.2.0] - 2026-10-01
### Added
* `runSoundness`, for whether a run measured what it set out to measure, and
`runFoundFailure`, for whether it found anything that fails it.
## [0.1.1.0] - 2026-07-29
### Fixed
* `writeManifestTxtFile` now writes UTF-8. It wrote through a binary handle
with `hPutStr`, which truncates every `Char` to its low byte, so any
non-ASCII character in a rendered source line came out as a different
character (`…` as `&`) or as an invalid UTF-8 byte. The `.json` manifest
was unaffected, as is the driver's `report.txt`, which already encoded
explicitly.
## [0.1.0.0] - 2026-07-16
* First released version.
