[5.1.0] - 2025-08-26

Added

• Heartbeat Monitor (implementations.HeartbeatMonitor)
• New logic for how logging is handled by Entities
  • The log_interval is now the interval with which an entity's value is checked, not necessarily logged
  • Whether a value is logged at the log_interval is controlled by:
    • max_interval: if this time is exceeded since the last log entry, then it will be logged; if 0 (default), then logging occurs every log_interval
    • max_absolute_change: if the value changes by more than this since the last log entry, then it will be logged
    • max_fractional_change: if the value changes fractional change is more than this since the last log entry, then it will be logged
  • The field that's checked for the max_fractional_change and max_absolute_change is given by check_field

Changed

• Methods for sending and receiving messages are moved to the mixin classes core.RequestHandler and core.RequestSender to capture how dl-py handles requests for both services and endpoints
• Upgrade dl-cpp to v2.10.6
• Docker build now separates the installation of dependencies into a separate stage

Fixed

• Postgres syntax
• Application cancelation -- can use ctrl-c or other system signals to cancel an executable
• Alerts exchange not hard-coded in the alerts consumer
