v0.19.0

Added

• Android Learn from a stream (ADR 0018): with Android's playback
  capture the phone hears the live stream it is playing (MS NOW, Xfinity
  Stream, any channel's web player) and learns every break into the same
  memory it uses at the TV — fingerprints, and words with Speech on; no TV
  is touched. Started from the Methods page; the notification counts the
  breaks. docs/print/AdHush-guide-stream-learning.pdf is the guide.
• Android memory that moves: Share this phone's memory zips the
  breaks, scripts and clock; Import memory from a file merges another
  phone's without doubling what is known.
