* sourceFinder cannot be async. ([#501](https://github.com/istanbuljs/istanbuljs/issues/501)) ([094f1b8](https://github.com/istanbuljs/istanbuljs/commit/094f1b83b4652c5ba492781620cb6358c685a849))

* mappedCoverage.addStatement is not a function ([#500](https://github.com/istanbuljs/istanbuljs/issues/500)) ([d77cc14](https://github.com/istanbuljs/istanbuljs/commit/d77cc147f7d791686af2975f7d906603335d0bfc)), closes [istanbuljs/nyc#940](https://github.com/istanbuljs/nyc/issues/940)

# [4.0.0-alpha.2](https://github.com/istanbuljs/istanbuljs/compare/istanbul-lib-source-maps@4.0.0-alpha.1...istanbul-lib-source-maps@4.0.0-alpha.2) (2019-10-09)

* Convert to async API ([#489](https://github.com/istanbuljs/istanbuljs/issues/489)) ([f8ebbc9](https://github.com/istanbuljs/istanbuljs/commit/f8ebbc9))

* MapStore#transformCoverage is now async and returns a

the coverage data only.  The `sourceFinder` method is now async and

provided directly on the `MapStore` instance.

# [4.0.0-alpha.1](https://github.com/istanbuljs/istanbuljs/compare/istanbul-lib-source-maps@4.0.0-alpha.0...istanbul-lib-source-maps@4.0.0-alpha.1) (2019-10-06)

* **package:** update rimraf to version 3.0.0 ([b6e7953](https://github.com/istanbuljs/istanbuljs/commit/b6e7953))

* Accept SourceStore and sourceStoreOpts options ([#482](https://github.com/istanbuljs/istanbuljs/issues/482)) ([0dc45a6](https://github.com/istanbuljs/istanbuljs/commit/0dc45a6))

* Add addInputSourceMapsSync and getSourceMapSync methods ([#484](https://github.com/istanbuljs/istanbuljs/issues/484)) ([dd7048e](https://github.com/istanbuljs/istanbuljs/commit/dd7048e))

* sourceStore and tmpdir options are removed.

# [4.0.0-alpha.0](https://github.com/istanbuljs/istanbuljs/compare/istanbul-lib-source-maps@3.0.6...istanbul-lib-source-maps@4.0.0-alpha.0) (2019-06-19)

* Update dependencies, require Node.js 8 ([#401](https://github.com/istanbuljs/istanbuljs/issues/401)) ([bf3a539](https://github.com/istanbuljs/istanbuljs/commit/bf3a539))

## [3.0.6](https://github.com/istanbuljs/istanbuljs/compare/istanbul-lib-source-maps@3.0.5...istanbul-lib-source-maps@3.0.6) (2019-04-24)
