v2.2.0-alpha.0

New features:

• Add the plugin option ts_nocheck to support most strict compiler options in userspace, see #152.
• The new plugin option add_pb_suffix adds the suffix _pb to all file names, see #186.
• Add service/method name to RpcError, see #197
  Thanks to @jcready for the contribution.
• Support JavaScript output via plugin option output_javascript, see #200.

Bug fixes:

• Use TextDecoder API for decoding UTF-8 from binary data, see #184.
  We have been using protobuf.js' algorithm to decode UTF-8, but it has had bugs
  in the past. For best possible compatibility, we have switched to the TextDecoder API.
  See MANUAL for details.
