v1.16.0

The bee team is excited to announce v1.16.0! 🎉

The team has been busy researching and testing ways to help swarm remain a reliable and healthy network, and to that end, we are happy to announce a brand new health service, salud.

With salud, nodes will periodically perform certain health checks on it's connected peers with data acquried from the status protocol. The checks as of this release are based on the duration of response to the status protocol msg, number of connected peers, the storage radius, and total batch commitment as computed by each peer.

For duration and number of connected peers, each peer must be within the 80th percentile to be deemed as healthy. Radius and batch commitment are measured in terms of the most common values as reported by each connected peer. Measurements are created anew for each peridoic health check.

A self check is also in place where if the node's own storage radius does not match with the rest of the networks', the node won't participate in the schelling game.

With this release, only the pushsync protocol utilizes the filtering of peers for requests based on the status of health.

Breaking changes

• The status protocol now includes the reachability of a peer and the total batch commitment of the network reported by each peer (#4054, #4042)

Bug fixes

• Fixed the last played round field in the redistribution state endpoint to report the corrent round instead of the previous round. ( #4062)

Hardening

• Loosed the requirements of the pushsync protocol so that in the case a neighborhood is down or does not exist, the chunk is pushed as close as possible to it's neighborhood. (#4064)
• Increased the wake up interval for the depthmonitor from 5 to 15 minutes. (#4068)
