 ## Known Limitations
 ### Known limitations for TS compiler options
 - You can't use `"target": "ES6"` while using `node v4` in your test environment;
-- You can't use `"jsx": "preserve"` for now (see [progress of this issue](https://github.com/kulshekhar/ts-jest/issues/63));
 - If you use `"baseUrl": "<path_to_your_sources>"`, you also have to change `jest config` a little bit (also check [Module path mapping](#module-path-mapping) section):
