* Correctly deshadow variables that conflict with imports ([#68](https://github.com/rollup/rollup/issues/68))

## 0.12.0

* Internal re-architecting, resulting in more efficient bundling with reduced memory usage
* Shorthand properties are expanded if necessary ([#61](https://github.com/rollup/rollup/issues/61))

* Allow imports of external modules for side-effects ([#55](https://github.com/rollup/rollup/pull/55))

## 0.11.4

* Side-effect preservation applies to internal default exports ([#43](https://github.com/rollup/rollup/issues/43))

## 0.11.3

* Class methods are not incorrectly renamed ([#42](https://github.com/rollup/rollup/issues/42))
* External modules are assigned names before canonical names are determined ([#42](https://github.com/rollup/rollup/issues/42))

## 0.11.2

* Correctly handle computed properties (e.g. `foo[bar]`) when discovering dependencies ([#47](https://github.com/rollup/rollup/pull/47))

## 0.11.1

* Support for `export * from '..'` ([#46](https://github.com/rollup/rollup/pull/46))

## 0.11.0

* Experimental browser-friendly build (`dist/rollup.browser.js`) ([#25](https://github.com/rollup/rollup/issues/25))
* Internal re-architecting to make discovery process simpler and more performant
* Preservation of side-effects that happen in a separate module to the affected definition ([#39](https://github.com/rollup/rollup/issues/39))

## 0.10.0

* Better sorting algorithm – sorting happens at the module level, rather than the statement level. This avoids certain edge cases
* IIFEs are ignored for the purposes of distinguishing between 'strong' and 'weak' dependencies
* Empty `var` declarations for exported bindings are omitted

## 0.9.1

* Much faster statement insertion (fixes major 0.9.0 performance regression)

## 0.9.0

* BREAKING - `resolvePath` is now `resolveId`. The returned `id` (which by default is a filepath) is passed to the `load` function, which can optionally be overridden, and which is applied to all modules including the entry module. This allows custom resolver and loading logic for integration with third party systems (e.g. JSPM) or, eventually, in-browser usage ([#30](https://github.com/rollup/rollup/issues/30))
* A statement cannot appear after later statements from the same bundle ([#34](https://github.com/rollup/rollup/issues/34))
* Tricky cyclical dependencies are handled ([#36](https://github.com/rollup/rollup/issues/36))
* `sourcemap` option is used by CLI (was omitted previously)

## 0.8.3

* Correctly rename functions that have arguments with the same name ([#32](https://github.com/rollup/rollup/issues/32))
* Ensure unused default exports are given a legal name ([#33](https://github.com/rollup/rollup/issues/33))

## 0.8.2

* Support `moduleId` and `moduleName` via CLI ([#24](https://github.com/rollup/rollup/issues/24))

## 0.8.1

* Anonymous functions that are exported as default are converted to named function declarations for correct hoisting, rather than being bound to functions ([#29](https://github.com/rollup/rollup/issues/29))
* Automatically-generated default export names are deconflicted with local definitions ([#29](https://github.com/rollup/rollup/issues/29))

## 0.8.0

* Top-level variable declarations with multiple declarators are split up, to avoid unnecessary code importing and incorrectly-ordered statements ([#26](https://github.com/rollup/rollup/issues/26))
* `this` at the top level is `undefined` ([#28](https://github.com/rollup/rollup/issues/28))

## 0.7.8

* Avoid using `path.parse` - unsupported in node 0.10

## 0.7.7

* Promise `source-map-support` from `devDependencies` to `dependencies` ([#23](https://github.com/rollup/rollup/issues/23))

## 0.7.6

* Better placement of `export default` statements ([#21](https://github.com/rollup/rollup/issues/21))
* Prevent function calls and property assignments from being treated as rebinding for sake of unbound default exports
* Add `--external foo,bar,baz` option to CLI (equivalent to `external: ['foo', 'bar', 'baz']`)
* Add CLI tests

## 0.7.5

* Prevent accidental conflicts with the global namespace ([#20](https://github.com/rollup/rollup/issues/20))

## 0.7.4

* More precise statement re-ordering to satisfy `export default` constraint (fixes bug introduced in 0.7.3)

## 0.7.3

* Default exports are not bound. To enable this, statements within a module are sorted to retain their original order ([#15](https://github.com/rollup/rollup/issues/15))
* Better positioning of comments ([#14](https://github.com/rollup/rollup/issues/14))
* Various fixes to get Travis-CI rigged up

## 0.7.2

* Fix sourcemap paths on Windows ([#6](https://github.com/rollup/rollup/pull/6))

## 0.7.1

* Named functions can be used as default exports from a bundle
* Method calls are assumed to mutate the owner (i.e. `foo.bar()` mutates `foo`) ([#13](https://github.com/rollup/rollup/issues/13))
* `options.indent` can be used to control indentation of resulting bundle. `options.true` (default) means 'auto', `options.false` means empty string. Alternatively specify whitespace e.g. `'  '` or `'\t'` ([#5](https://github.com/rollup/rollup/issues/5))

## 0.7.0

* Ensure statements are always separated by a newline ([#9](https://github.com/rollup/rollup/pull/9))
* Use CommonJS `exports` correctly (UMD exports)
* Throw error if `moduleName` is required but missing (UMD exports)
* Attach IIFE global to `this` rather than `window`
* Allow names inside bundle to the the names of `Object.prototype` properties ([#12](https://github.com/rollup/rollup/pull/12))
* Keep exports live ([#11](https://github.com/rollup/rollup/pull/11))

## 0.6.5

* Add sourceMappingURL comment to code, as appropriate
* Higher resolution sourcemaps

## 0.6.4

* Fix CJS bundling with default export

## 0.6.3

* Fix exports and external module imports with some output formats
* Fix endless cycle bug on Windows ([#3](https://github.com/rollup/rollup/pull/3)) - thanks @Bobris

## 0.6.2

* Permit assignments to properties of imported bindings

## 0.6.1

* Support for basic transformers

## 0.6.0

* BREAKING - `rollup.rollup` and `bundle.write` both take a single options argument
* BREAKING - external modules must be declared upfront with `options.external: [...]`
* Non-relative module paths will be resolved by looking for `jsnext:main` fields in the appropriate `package.json` files. This behaviour can be overridden by passing an alternative `resolveExternal` function
* Fix sourcemap options
* Include CLI files in npm package (duh)

## 0.5.0

* Command line interface
* Sourcemap generation
* Correct behaviour with `export { x as y } from 'z'`

## 0.4.1

## 0.4.0

* Self-hosting! `rollup.rollup` now rolls up rollup

* Prevent shadowing of external modules
* Rewrite computed property identifiers where necessary
* Preserve original statement order where possible
* Internal refactoring
