v5.5.1

Fixed

• The web interface's nature theme no longer draws a hard outline around the
  home page cards in its dark scheme, so their edges stay soft as in the light
  one. (#515)
• The agent contract, the ontology and the guides to configuring and customising
  skills now name conversation skills beside assignment skills, where they spoke
  of conversation prompts before. The agent contract stays at version 1, and
  existing skills and prompts need no change.
  (#513)

What's Changed
