0.5.0

Changed

• Update xtra to upstream. This involved re-implementing some of the features
  in comit-network's fork internally. Xtra message handler metrics were also
  removed in favour of the new instrumentation feature combined with
  Grafana Tempo's span metrics.
• Allow rollovers from previous versions for takers to make the rollover protocol more resilient against the maker being ahead and avoid consecutive rollover failure.

Removed

• The initial tour through ItchySats. The underlying library caused issues that could not be overcome.

Added

• Add new argument to the maker: ignore-migration-errors. If enabled, the maker will start if an error occurred when opening the database, if not, it will fail fast. This can come handy to prevent accidentally creating a new empty database in case database migration was unsuccessful.
• New metrics: the maker tracks how many offers have been sent (offer_messages_sent_total) and the taker tracks how many offers have been received (offer_messages_received_total).
• Allow taker to provide extended private key as argument when starting. This key will be used to derive the internal wallet according to (Bip84)[https://github.com/bitcoin/bips/blob/master/bip-0084.mediawiki].
• Support for tokio console for debugging. It can be activated with --tokio-console.
• Show the daemon-version in the info box of the taker-ui.
• Add support for instrumented traces for debugging. It can be activated with --instrumented.

Fixed

• An issue where electrum-client caused high CPU load.
• An issue where the pings were triggered too frequently and caused congestion in the endpoint.
