+## [4.0.0] - 2022-05-02
+
+### Changed
+
+- Ignore `--project`/`-P` CLI flag when explicit options are passed to `register`. See PR [#206](https://github.com/dividab/tsconfig-paths/pull/206).
+- Tolerate an undefined `baseUrl` compiler option. See PR [#208](https://github.com/dividab/tsconfig-paths/pull/208).
+
+### Added
+
+- Add `cwd` option to `register` function that overrides where the `tsconfig.json` search begins. See PR [#205](https://github.com/dividab/tsconfig-paths/pull/205).
+- Add support for `jsconfig.json`. See PR [#199](https://github.com/dividab/tsconfig-paths/pull/199). Thanks to [@F3n67u](https://github.com/F3n67u) for this PR!
+- Let `paths` mappings be absolute paths. See PR [#184](https://github.com/dividab/tsconfig-paths/pull/184).
+- Allow `baseUrl` in `tsconfig.json` to be an absolute path. See PR [#174](https://github.com/dividab/tsconfig-paths/pull/174). Thanks to [@nwalters512](https://github.com/nwalters512) for this PR!

+Use this to load modules whose location is specified in the `paths` section of `tsconfig.json` or `jsconfig.json`. Both loading at run-time and via API are supported.
 
 Typescript by default mimics the Node.js runtime resolution strategy of modules. But it also allows the use of [path mapping](https://www.typescriptlang.org/docs/handbook/module-resolution.html) which allows arbitrary module paths (that doesn't start with "/" or ".") to be specified and mapped to physical paths in the filesystem. The typescript compiler can resolve these paths from `tsconfig` so it will compile OK. But if you then try to execute the compiled files with node (or ts-node), it will only look in the `node_modules` folders all the way up to the root of the filesystem and thus will not find the modules specified by `paths` in `tsconfig`.
 
-If you require this package's `tsconfig-paths/register` module it will read the `paths` from `tsconfig.json` and convert node's module loading calls into to physical file paths that node can load.
