Several (mostly deprecated) options have been removed or renamed (#2293, #2409):
- banner -> output.banner
- dest -> output.file
- entry -> input
- experimentalCodeSplitting -> now always active
- experimentalDynamicImport -> now always active
- experimentalPreserveModules -> preserveModules
- exports -> output.exports
- extend -> output.extend
- footer -> output.footer
- format -> output.format
- freeze -> output.freeze
- globals -> output.globals
- indent -> output.indent
- interop -> output.interop
- intro -> output.intro
- load -> use plugin API
- moduleName -> output.name
- name -> output.name
- noConflict -> output.noConflict
- output.moduleId -> output.amd.id
- outro -> output.outro
- paths -> output.paths
- preferConst -> output.preferConst
- pureExternalModules -> treeshake.pureExternalModules
- resolveExternal -> use plugin API
- resolveId -> use plugin API
- sourcemap -> output.sourcemap
- sourceMap -> output.sourcemap
- sourceMapFile -> output.sourcemapFile
- strict -> output.strict
- targets -> use output as an array
- transform -> use plugin API
- useStrict -> output.strict
In general, output options can no longer be used as input options (#2409)
bundle.generate and bundle.write now return a new format (#2293)
Several plugin hooks have become deprecated and will display warnings when used (#2409):
- transformBundle
- transformChunk
- ongenerate
- onwrite
Plugin transform dependencies are deprecated in favour of using the this.addWatchFile plugin context function (#2409)
Accessing this.watcher in plugin hooks is deprecated in favour of the watchChange plugin hook and the this.addWatchFile plugin context function (#2409)
Using dynamic import statements will by default create a new chunk unless inlineDynamicImports is used (#2293)
Rollup now uses acorn@6 which means that acorn plugins must be compatible with this version; acorn is now external for non-browser builds to make plugins work (#2293)

Features

The --dir ClI option can now be aliased as -d (#2293)
The --input option now supports named entry points via = (#2293)

Bug Fixes

Both the --input option as well as the default CLI option now support named inputs (#2293)

2018-12-16

Breaking Changes

optimizeChunks is renamed to experimentalOptimizeChunks to reflect this feature is not production-ready yet (#2575)

Features

Plugins can iterate all module ids via this.moduleIds (#2565)
Plugins can get graph information about a module via this.getModuleInfo(id) (#2565)
Plugins and JS API users get more information about the generated chunks: dynamicImports, facadeModuleId, isDynamicEntry, name (#2575)
Tree-shaken dynamic imports will no longer create chunks or influence chunking in any way (#2575)
Dynamic imports will no longer follow the entryFileNames but the chunkFileNames property reflecting those are solely internally used (#2575)
If there are chunk naming conflicts, entry chunks will always take precedence (#2575)
If an entry facade is created, only the facade chunk is marked as isEntry (#2575)
Dynamic chunks will only be marked as isEntry if they are actually entry chunks as well; thus there is now a 1-to-1 correspondence between modules listed in input and chunks marked as isEntry (#2575)
Chunks no longer contain imports for variables that are tree-shaken in the chunk but used in other chunks (#2584)
Chunks will always import re-exported variables directly from the chunk where they are originally exported from (#2584)
Null characters will be pruned from chunk ids to allow for virtually created chunks and make rollup-plugin-multi-entry compatible with code-splitting and thus the upcoming 1.0 version (#2590)
Simplify the UMD wrapper code as much as possible, especially if there are no exports (#2594)
The UMD wrapper will now work in strict mode by checking for self before this when determining the global variable (#2594)

Bug Fixes

If a facade is created for a dynamic entry point, this facade will be imported instead of the facaded chunk (#2575)
Manual chunks that include multiple entry points will have proper facades created for all entry points if necessary (#2575)
If missing exports are shimmed, the shim variable will not be global but created on a per-module basis and is deconflicted with variables having the same name (#2584)
Missing export shims work properly in SystemJS (#2584)
preserveModules now handles dynamic namespace imports (#2584)
Fix chunk execution order in certain scenarios (#2584)
Exports and assignments using destructuring syntax will properly update the exported variables when generating SystemJS output (#2587)
Hashes in chunk names will now also take dynamic imports into account (#2596)

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)

0.19.1

Fix module.basename() when used with custom resolveId function
Use rollup-babel to build self

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)
New intro and outro options – similar to banner and footer except inserted inside any format-specific wrapper
Multiple var declarations in an export block (e.g. export let a = 1, b = 2) are split up to facilitate tree-shaking (#171)
More informative error when using a missing namespace property (#169)

Internal refactoring (#99)
Optimisation for statically-analysable namespace imports (#99)
Windows support (theoretically!) (#117 / #119)

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)

A single binding can be exported under multiple names (#18)
useStrict option exposed to CLI as --strict/--no-strict (#81)
Neater exports from ES6 bundles

Experimental browser-friendly build (dist/rollup.browser.js) (#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)

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.

Promise source-map-support from devDependencies to dependencies (#23)

0.7.6

Prevent accidental conflicts with the global namespace (#20)

0.7.4

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)
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)

0.7.0

Ensure statements are always separated by a newline (#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

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'
