v2.15.2

• Fixed a case where custom plugins specified by command line could silently fail.

  Specifically, if a plugin relies on the init-hook option changing sys.path before
  it can be imported, this will now emit a bad-plugin-value message. Before this
  change, it would silently fail to register the plugin for use, but would load
  any configuration, which could have unintended effects.
