SystemJS Builder 0.10.0

Breaking Changes

• Transpilers are now loaded as modules, see the SystemJS 0.16 release notes https://github.com/systemjs/systemjs/releases/tag/0.16.0.
• babel-core needs to be installed explicitly as a dependency and is no longer included in the tree by default.
• builder.trace now returns a direct tree object instead of an intermediate trace object.
• SFX bundles now attempt to include the Traceur or Babel runtime by default if needed. This can be disabled with the runtime: false build option.
• All bundles now contain fully-normalized dependencies. This restricts production-time mappings, but means that map config is not needed at all in production unless dynamic normalization and loading scenarios are required.

New Features

• builder.build, builder.buildSFX (#108) and builder.trace now support arbitrary arithmetic expressions, supporting wildcards (#104), single module arithmetic (#111), and a new commonality operator (#113).
• Babel helpers are now used by default instead of inlining the helpers for every module (#105).
• SFX bundles now include the Traceur or Babel runtime by default if used (#46).
• Plugins with build: false set will now be included in the trace (#89).
• Uglify dead code removal is now enabled by default for bundles, with a globalDefs option which can now be passed in with the build configuration (#116).
• Traceur and Babel are only loaded on demand allowing for faster require time (be817ae).
• builder.getDepCache helper for generating the depCache configuration for a traced tree.
• Build output includes a modules array which can directly be used to populate bundles configuration.

Bug Fixes

• Declarative SystemJS configuration is now supported (#98)
• Arithmetic provides useful error messages for invalid syntax (#112)
• SFX bundles have been updated to match SystemJS 0.16 fixes (#118)
• AMD dependency dedupe fix (#110)
