v0.17.0-dev.2

Added

• New feature for TryCP to allow logs to be downloaded. This is useful when you are working with remote nodes and need
  to read the Holochain logs locally. The logs are given back as raw bytes, so you can write them to a file or otherwise
  further process them. #222

Removed

Changed

• The TryCP server used to open a new admin websocket for each admin request made to Holochain. A single
  admin websocket is now used for all requests. It is opened by the first request and closed when the Holochain instance
  it shut down. #221

Fixed

• The trycp_client now handles ping/pong messages from the TryCP server to keep the connection alive.
• The trycp_client now handles the close event from the TryCP server to close the connection.
