What's New 1.60+

This page is the high-level overview of the structural changes introduced since 1.60. Detailed explanations are maintained in the linked domain chapters.

Current scope

This overview is kept on a 1.60+ basis and reflects the current architecture line beyond the original 1.60 release. It is not limited to the first 1.60.x implementation state.

Core themes of the current generation:

• adaptive PID control with L/R-based AutoTune
• FSM-driven process orchestration for mash, autotune, manual, and fermenter flows
• runtime snapshot and controller-deck model for WebIf, SSE, display, and testflow
• dashboard and chart improvements, including clearer controller visibility and additional sensor curves
• safer backup/restore, upload, import, and file-handling paths
• decoupled IDS RMT send path and broader hardware support beyond IDS-only setups

Where the content lives now

• PID engine details: PID engine reference 1.60+ (Power User)
• Brew-day decisions: Brew-day quick guide
• FSM orchestration: FSM process flow 1.60+ (Power User)
• IDS RMT sending: IDS RMT send logic 1.60+ (Power User)

What changed conceptually since pre-1.60 firmware

The change is structural, not only parameter-level:

1. from Ku/Pu oscillation tuning to L/R model tuning
2. from ticker-driven execution to FSM/task orchestration
3. from mostly classic PID focus to phase-oriented process guidance
4. from scattered runtime state handling to a central runtime snapshot model
5. from more fragile file/update paths to safer restore, upload, and import handling
6. from IDS-focused perception to a broader control platform for induction, relay, and webhook actuator paths

Practical result

For brewers, the 1.60+ line mainly means:

• more reproducible temperature behavior
• clearer tuning levers
• more robust process execution
• broader hardware flexibility
• more stable WebIf and device-state handling
