• Update deps

0.20.0

• Support for plugins (#207)
• BREAKING – options.transform, options.load, options.resolveId, options.resolveExternal and options.external are no longer supported, and should be handled by plugins. More info
• BREAKING – the .js extension is only added if it looks like there's no extension, allowing e.g. import data from 'data.json' (with the appropriate transformer). For safety, always include the file extension – import ./foo.js, not ./foo

0.19.2

• Fix exporting namespaces to include all of their exports (#204)
• Namespace exotic objects are frozen to ensure that its properties cannot be modified, reconfigured, redefined or deleted (#203)

• Use rollup-babel to build self
• Exposed the version string through the API: require( 'rollup' ).VERSION

0.19.0

• breaking The transform option is no longer passed through to custom loaders. Loaders should only concern themselves with providing source code; transformation will always take place
• options.transform functions can return a string, or a {code, map, ast} object. Where possible, sourcemap chains will be flattened (#175)
• options.resolveId, options.resolveExternal and options.load can each be a function or an array of functions. If an array, the first non-null/undefined return value is used. In both cases, failed resolution/loading will fall back to the defaults, unless an error is thrown. (#174)

• Multiple var declarations in an export block (e.g. export let a = 1, b = 2) are split up to facilitate tree-shaking (#171)

• Only rewrite foo as exports.foo when it makes sense to (#92)
• Fix bug with shadowed variables that are eventually exported (#91)
• Exclude unused function declarations that happen to modify a used name (#90)

• this at the top level is undefined (#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)

0.7.6

• Add CLI tests

0.7.5

• Prevent accidental conflicts with the global namespace (#20)

0.7.4

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

0.7.3

• Better positioning of comments (#14)
• Various fixes to get Travis-CI rigged up

0.7.2

• Fix sourcemap paths on Windows (#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)

• Use CommonJS exports correctly (UMD exports)
• Throw error if moduleName is required but missing (UMD exports)

• 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
