[0.18.0] - 2026-03-20 09:21 - Nigel Mansell Release

• Relentless pace
• Controlled aggression
• Occasional wild bursts
• No fear of the edge

White-knuckle,high-grip performance

Added

• An event type field to the Hydra MQ EventMsg, used by HydraEventMQ.
• A Memory widget that displays the size of (number or stored sequences) and relative health (cells are shaded) of the 20 Adaptive Replay Memory Buckets
  • Published new telemetry information to populate this widget.
• Two new report sections in the Snapshot Report:
  1. A table showing Epoch, Gear, Seq Length, Batch Size, Mean, and Median values every 500 episodes.
  2. A table showing the bucket sizes for the 20 ATH Replay Memory buckets every 500 epochs.
• Adaptive Memory Horizon - Replay Memory Automatic Gearbox
  • See the documentation for more information on this feature

Changed

• Minor TUI layout changes.
• Refactored the ATHReplayMemory
  • A ATHDataStore to house the Replay Memory data.
  • A ATHDataMgr to manage the contents of the ATHDataStore
  • Created a ATHGearbox class that dynamically changes the sequence length and batch size of the training data based on the state of the ATHDataStore.
  • A ATHMemory class to orchestrate the other new ATH classes
  • A small ATHCommon module to house the GearMeta and Episode dataclasses.
  • Minor refactor of ATH Constants.

Fixed

• Batch size and sequence length are now correct in the TUI.
  • For RNNs these are set on the server size by the Adaptive Replay Memory
  • The Adaptive Replay Memory changes these as the game proceeds. These changes are published on the ZeroMQ Events topic. The client is a subscriber to this topic. The client correctly updates the values in the TUI when they change on the server.
