v0.2.0

• nohead assets list --search <words> finds assets whose filename or alt
  text has every word, and --kind image,video lists only assets of those
  kinds (image, video, audio, document or other). --all follows
  every page, and --cursor continues from one: without them the list ends
  at 100 with the cursor for the next page, as records list does.

• Breaking (for scripts): nohead --version also prints the SDK version
  it calls the API through, such as 0.2.0 (SDK 0.7.0). The CLI's own version stays
  the first word; a script that compares the whole output should read that
  word instead (nohead --version | cut -d" " -f1).
