+# mutator 0.2.0

+- Added first-class `tinytest` support. A package with an `inst/tinytest`
+  directory is now auto-detected and its mutants are run in-process with
+  `pkgload::load_all()` and `tinytest::run_test_dir()`, without an install per
+  mutant, including coverage-guided test selection.
+- Added a `strategy` argument to `mutate_package()` to override test-framework
+  auto-detection. Accepted values are `"auto"` (the default), `"testthat"`,
+  `"tinytest"`, `"tinytest-installed"`, and `"installed"`.
+- Added a `tinytest-installed` strategy that installs each mutant and runs
+  `tinytest::test_package()`. It is a fallback for packages whose in-process
+  load diverges from an installed copy and unlike the generic
+  installed-tests fallback it still supports coverage-guided selection.
+- Reworked the README and configuration vignette, documenting how the test
+  strategy is selected and when to override it.
+- Fixed the `per_file` coverage backend to forward the package's
+  `tests/testthat.R` harness arguments (notably any `filter`) to
+  `testthat::test_dir()`, matching the `record_tests` backend.
