Breaking

• Multicast group change: Regeneration of all multicast group allowlists required, as allowlists are now stored within each Access Pass instead of at the multicast group level.

Changes

• CLI
  • Added a wait in the disconnect command to ensure the account is fully closed before returning, preventing failures during rapid disconnect/reconnect sequences.
  • Display multicast group memberships (publisher/subscriber) in AccessPass listings to improve visibility.
  • Allow AccessPass creation without 'client_ip'
  • Add 'allow_multiple_ip' argument to support AccessPass connections from multiple IPs
  • Include validator pubkey in export output
  • Rename exchange.loc_id to exchange.bgp_community
• Activator
  • Reduce logging noise when processing snapshot events
  • Wrap main select handler in loop to avoid shutdown on branch error
• Onchain programs
  • Remove user-level allowlist management from CLI and admin interfaces; manage multicast group allowlists through AccessPass.
  • Add Validate trait for core types (AccessPass, Contributor, Interface, etc.) and enforce runtime checks before account operations.
  • Fix: resize AccessPass account before serialization to prevent errors; standardized use of resize_account_if_needed across processors.
• Internet telemetry
  • Add circuit label to metrics; create a new metric for missing circuit samples
  • Create a new metric that tracks how long it takes collector tasks to run
  • Submit partitions of samples in parallel
  • Include circuit label on submitter error metric
• Monitor
  • Reduce logging noise in 2z oracle watcher
  • Include response body on 2z oracle errors
  • Collect contributors and exchanges into InfluxDB
• Device controller
  • When a device is missing required loopback interfaces, provide detailed errors to agent instead of " not found". Also, log these conditions as warnings instead of errors, and don't emit "unknown pubkey requested" error metrics for these conditions
  • Add device info as labels to controller_grpc_getconfig_requests_total metric
• Device agents
  • Submit device-link telemetry partitions in parallel
• Onchain programs
  • Enable AccessPass with 'client_ip=0.0.0.0' to dynamically learn the user’s IP on first connection
  • Enable AccessPass to support connections from multiple IPs (allowlist compatibility)
  • Rename exchange.loc_id to exchange.bgp_community, and change it from u32 to u16
• Telemetry data API
  • Filter by contributor and link type
• SDK/Go
  • String serialization for exchanges status
  • Exclude empty tags from influx serialization
