What's new

Project Atmosphere 0.8.1.0

Project Atmosphere 0.8.1.0 continues the large internal refactor of the forecast and runtime systems, focusing on simulation stability, improved diagnostics, and better atmosphere state correctness.

This update stabilizes the new region-first runtime architecture while introducing deeper telemetry tools and improved safeguards for live atmospheric evolution.

Note:
This update is temporarily incompatible with PA x TFC.
A compatibility update is already planned and will restore support soon.


Changes

Forecast and Runtime

  • Continued the transition to a region-first forecast runtime architecture.
  • Reduced reliance on legacy biome-key runtime systems.
  • Forecast baselines have been stabilized as part of the ongoing refactor.

Atmosphere Simulation

  • Added humidity budget instrumentation, including ocean and wind integration.
  • Completed the cloud-water coupling system for humidity simulation.
  • Added pressure restore toward forecast targets with soft deviation guards and anomaly reporting.
  • Added temperature restore toward forecast targets with soft deviation guards and anomaly reporting.
  • Reworked cyclone and cloud ownership logic so cyclone-driven storm visuals are no longer immediately overwritten by cloud sampling.

Telemetry and Debugging

  • Added new telemetry exports for atmosphere coupling, including target vs live values for:
    • Temperature
    • Pressure
    • Humidity
  • Added humidity budget diagnostics and improved tracking of cloud-water interactions.
  • Added anomaly markers to help diagnose pressure and temperature drift during runtime.

Compatibility

  • Dynamic Trees compatibility remains optional, allowing the mod to load normally even if Dynamic Trees is not installed.(This module is a work in progress you should always disable it)

Fixes

  • Fixed a telemetry export crash on JDK 17 caused by Gson reflective access to java.time.Instant.
    Explicit serialization for Instant is now used.

Notes

  • This release contains no client or HUD changes.
  • Build verified successfully on JDK 17.

Ongoing Work

  • Forecast generation is now in a stable state.
  • Current tuning work focuses on live runtime evolution, particularly temperature and humidity oscillations observed in some active regions.
