+## 1.0.0 (2020-11-19)
+
+
+### ⚠ BREAKING CHANGES
+
+* new test-exclude with modified exclude rules (#179)
+* **istanbul-reports:** lcov reports now use relative paths (#168)
+* Node.js' source-map and lineLength cache is now used to remap coverage output (this allows tools like ts-node to be supported, which transpile at runtime).
+* temp directory now defaults to setting for report directory
+* c8 will now load source-maps if possible and remap coverage accordingly
+* switches to using NODE_V8_COVERAGE rather than inspector directly
+* dropped subprocess support for the time being, while we march towards an initial implementation.
+
