- __rpc__ - Several `getblocktemplate` improvements have been implemented for
  more accuracy. e.g. `curtime` will now be updated each call.
- __mining__ - The internal miner API has been rewritten, and now mimics
  stratum in a sense.
- __chain__ - Faster verification with checkpoints.
- __net__ - Fixed a potential block stalling issue.

  for better shipping with browsers.
