Safe v1.5.8

New Features

• Added safe auth status command. It prints out information about the
  current auth token.
• Added --json flag to safe auth status. It prints out said information
  in a JSON format.

Improvements

• safe targets --json output now includes if the target expects
  a Strongbox server to be present, and also the targeted Vault namespace,
  if any.

Bug Fixes

• safe auth now respects the -T flag when writing the token.
• safe local no longer races with the Vault server actually listening on its endpoint, and will wait up to 5 seconds for it to begin listening.
