Features

• static analysis for CommonJS now supports reexports via
  • module.exports = require("...")
  • module.exports.a.b.c = require("...").a.b.c
  • Unused exports for these constructs are elimiated, but export names are not mangled yet
• add optimization.realContentHash option
  • defaults to true in production mode
  • a real content hash is calculated for [contenthash] after asset processing, e. g. for minimizing etc.
• add output.charset option
  • defaults to true
  • setting it to false omits the charset attribute on injected scripts
• expose require("webpack-sources") as require("webpack").sources
  • avoids version conflict with different webpack-sources version
  • webpack should be consumes as peerDependecy by plugins
