Release notes
Channels routing policies adjustments
Channels routing policies are adjusted based on the channel state (capacity, local balance) and the amount of satoshis forwarded in the last activity period (agent.intervals.routing_policies).
Apart from this, Hydrus adjusts the maximum HTLC value to 80% of the local balance. It is not set to the exact local balance to leave a buffer of 20% of the funds, in order to avoid running out of liquidity and failing to route payments before the next update.
CLI commands
Agent instructions and scores queries now have their own command to execute them separately. To run all agent tasks (open/close/updates) use the agent run command.
New commands:
| Name | Description |
|---|---|
agent run
| Run the agent, executing channels and routing policies evaluations on intervals |
channels close
| Evaluate local channels to close and create the closing transactions |
channels open
| Evaluate nodes to connect to and create the funding transaction |
channels updatepolicies
| Evaluate local channels and update their routing policies |
scores channels
| Show local channels scores |
scores nodes
| Show network graph nodes scores |
Built-in tasks scheduling
Choose how often to open/close channels or update routing policies without having to use systemd timers or cron jobs.
New configurations:
| Name | Type | Description |
|---|---|---|
agent.intervals.channels
| time | Channels modifications interval |
agent.intervals.routing_policies
| time | Routing policies modifications interval |
New open heuristic
This release introduces a new open channel heuristic called channels.block_height.
Good channels are typically kept open for longer because they are profitable or useful, take the age of channels into account when choosing peers with this new heuristic.
Dependencies upgrade
Direct and indirect dependencies have been upgrade to their latest versions.
