Breaking changes:

- ts-loader now officially only supports webpack 2.  ts-loader 2.x may work with webpack 1 but it is not supported.  Related to that, all continuous integration tests now run against webpack 2.   
- as webpack 2 does not support node 0.12 neither does ts-loader from now.  node 4 at least is required.

## v1.3.3

- [Fix bug when "extend"ing a tsconfig that specifies "allowJs"](https://github.com/TypeStrong/ts-loader/pull/415) Thanks @cspotcode
- [Minor perf optimisations](https://github.com/TypeStrong/ts-loader/pull/412)

## v1.3.2

- [Upgrade enhanced-resolve to v3](https://github.com/TypeStrong/ts-loader/pull/411)
- [Remove arrify dependency](https://github.com/TypeStrong/ts-loader/pull/410)

## v1.3.1

- [Rolled back re-exported const enums no longer break emit in watch mode as performance cost was too high](https://github.com/TypeStrong/ts-loader/pull/406) resolves #393

## v1.3.0

- [Introduce meaningful error when importing TypeScript from `node_modules`](https://github.com/TypeStrong/ts-loader/pull/399)
- [Introduce `entryFileIsJs` loader option which allows having an entry file which is js.](https://github.com/TypeStrong/ts-loader/pull/399) resolves #388 and #401 - thanks @Wykks and @pqr.  

NB Previously the `entryFileIsJs` option was on by default when `allowJs` was true.  Now it has to be specified directly.  Strictly speaking this is a breaking change; however given this is a rarely used option which exists for what is arguably an edge case this is being added without moving to 2.0.  If this breaks people then we'll never do this again; I'd be surprised if anyone is relying on this though so we're taking a chance.  Related tests have been suffixed "-entryFileIsJs" in the test name.

- Loader output is now written to stderr instead of stdout. (#95, #103)

## v0.6.1

- Improve initial build performance significantly for larger projects (#100)
- Fix issue with nightly (#96)

  means that TypeScript will resolve files exactly the same as webpack does (supporting aliases, etc).
  See the [aliasResolution test](test/aliasResolution) for an example. Only supported in TS 1.6 and
  above.
- Rework error reporting to resolve certain edge cases with dependencies. In general errors should
  be much more consistent now in watch mode.

- TypeScript options can be set through the loader option `compilerOptions`
- Improved error reporting
  - Errors from all files in the TypeScript application are now reported in watch mode instead of 
    from just those files that changed. This means that making a breaking change in a dependency
    will now be correctly reported as an error in the dependent file.
  - Errors with TypeScript options are now reported as webpack errors instead of logged to console
  - Error output no longer contains the filename once from webpack and again in the error message.
    Instead, the filename is only reported by webpack
  - Fixed issue with latest version of webpack where filenames could be reported twice for the same
    error in certain situations

  and nightly TypeScript. Many new tests have been added.
