 ## Support for decorators when targeting ES3
 
-Decorators are now allowed when targeting ES3. TypeScript 1.7 removes the ES5-specific use of `reduceRight` from the `__decorate` helper. The changes also inline calls `Object.getOwnPropertyDescriptor` and `Object.defineProperty` in a backwards-compatible fashion that allows for a to clean up the emit for ES5 and later by removing various repetitive calls to the aforementioned `Object` methods.
