# Changelog

## 0.5.0 - 2026-06-08

### Added
- WPA2 AP configuration API and WebUI controls.
- AP reset recovery action with regenerated password.
- Status API field filtering for smaller dashboard/WebUI payloads.
- Config page subtabs for General, WiFi/AP, Relays, Temperatures, BMS, and Maintenance.
- Relay button state/command feedback in the WebUI.
- Optional Cargo OLED display scaffold.
- GPIO plan assigning OLED I2C to GPIO 21/22 and setup button to GPIO 25.

### Changed
- Dashboard communication direction is now WiFi/HTTP API.
- Retired active dashboard UART pin usage.
- Improved WebUI visual styling, mobile temperature settings layout, and config form behavior during polling.
- Removed vehicle-specific branding from active project docs/examples.

### Fixed
- Config inputs no longer get overwritten while typing during polling.
- Temperature config lookup remains available outside disabled UART code.
- Misleading WebUI connection badge text.

## 0.4.0 - 2026-06-04

### Added

- Embedded tabbed WebUI.
- Overview, Battery, and Config tabs.
- Estimated runtime display.
- Battery detail page with BMS status, cell voltages, cell delta, capacity, remaining Ah, cycles, and battery temperature.
- WebUI setup workflow.
- Device name configuration from WebUI.
- Relay name configuration from WebUI.
- Temperature sensor name and enabled-count configuration from WebUI.
- Temperature probe scan and assignment workflow from WebUI.
- BMS enable/disable controls from WebUI.
- BMS reconnect action from WebUI/API.
- System restart action from WebUI/API.
- WiFi AP + STA mode.
- Multiple saved STA WiFi networks.
- WiFi priority and runtime reconnect behavior.
- HTTP/UART/USB serial command parity documentation.
- DS18B20 configurable temperature probe support.
- Preferred relay command endpoint: `POST /api/v1/relay/set`.

### Changed

- ESP32 remains the controller/source of truth.
- WebUI is now the preferred initial configuration workflow.
- Waveshare ESP32-S3 is the primary physical dashboard target.
- ESP32 relay board outputs are treated as control/trigger outputs for external fused automotive relays/contactors on major loads.
- BMS source now reports configured JBD BMS even when disconnected.

### Fixed

- Restored default NimBLE connection behavior after custom timeout caused BMS connection failures.
- Trimmed WiFi credentials from setup inputs.
- Improved WebUI organization by moving setup/configuration controls to the Config tab.

### Known Notes

- BMS connection can still temporarily block the ESP32 while attempting BLE connection if the BMS is out of range.
- WebUI BMS disable/enable controls are intended to make bench testing easier.
- DS18B20 multi-probe final install should use a proper terminal/distribution board rather than temporary Wago wiring.
