v0.7.0

Compare Source

• SourceMapConsumer now uses WebAssembly, and is much faster! Read about
  it here:
  https://hacks.mozilla.org/2018/01/oxidizing-source-maps-with-rust-and-webassembly/

• Breaking change: new SourceMapConsumer now returns a Promise object
  that resolves to the newly constructed SourceMapConsumer instance, rather
  than returning the new instance immediately.

• Breaking change: when you're done using a SourceMapConsumer instance,
  you must call SourceMapConsumer.prototype.destroy on it. After calling
  destroy, you must not use the instance again.

• Breaking change: SourceMapConsumer used to be able to handle lines,
  columns numbers and source and name indices up to 2^53 - 1 (aka
  Number.MAX_SAFE_INTEGER). It can now only handle them up to 2^32 - 1.

• Breaking change: The source-map library now uses modern ECMAScript-isms:
  let, arrow functions, async, etc. Use Babel to compile it down to
  ECMAScript 5 if you need to support older JavaScript environments.

• Breaking change: Drop support for Node < 8. If you want to support older
  versions of node, please use v0.6 or below.
