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)
