v2.2.8

This release brings a possibility to configure TCP keep alives. There is a relevant section in config file

# this defines a configuration for TCP keep alives. Default values are taken
# from Golang default behavior.
[network.keep-alive]
disabled = false
# idle means a time period after which we start sending TCP Keep Alive probes
idle = "15s"
# interval is a period between 2 consecutive probes
interval = "15s"
# if we miss that many probes, a connection will be considered as a dead one.
count = 9

As usual, default settings are decent enough. Also, there is a correct management for TLS GREASE cipher suites and some network related tuning.
