How to use this file:
- When making a change to the firmware that users should know about, add it to the
	appropriate section (breaking/added/fixed) in the next release.
- If it's something interesting or breaking, make a post about it on the forum! We want users
	to find out about changes before they have to get help because their car won't start.

## Unreleased

### Breaking Changes
 - Simplified VVT single tooth cam modes. "Single tooth second half" and "single tooth first half" have been replaced by simply "single tooth". This may require re-setting your trigger and VVT timing offsets if you used "single tooth first half" prior to this change. #178

### Added
 - Log per-cylinder true ignition timing (includes trim, knock retard, etc) #76
 - Add mode for CLT/IAT sensors that are installed "high side" instead of typical "low side" #116
 - Automatic supply voltage compensation for VVT solenoids, giving more stable control as battery voltage changes #209
 - Configurable ignition timing limits, adding safety particularly for engines running wasted spark with a large cam #211
 - Improved injection, ignition bench test UI and functionality: More gauges, fuel pump on/off buttons for injector testing, and configurable duration/count #219
 - Preset for Mazdaspeed Miata (NB) IAT sensor
 - Option to compensate Alpha-N fueling with intake air temperature
 - Gasoline-scale AFR gauge: instead of showing true AFR, show "gasoline scale" where 14.7 means stoichiometric
 - Decode fuel temperature from flex fuel sensors #254
 - Allow brief operation over 100% injector duty cycle and add configurable duty cycle limits #215
 - Buttons to bump VVT targets for testing/PID tuning
 - Improved serial port selection for FOME console and firmware update
 - Better default configuration values for some advanced features

### Fixed
 - Improved bench test resolution (more usable for testing injectors, dwell, etc)
 - Maximum knock retard table displays correct Y axis values in TunerStudio
 - Make errors about fuel pressure sensors less aggressive #111 #117
 - Always operate in "two wire" mode for batch fuel, fixing batch firing order #23
 - Fix "Toyota 3 Tooth Cam" VVT mode (1JZ, 2JZ, 1G, etc) actually works now #237
 - Fix autotune while TS project is in AFR mode - corrections now made properly for target AFR table values
 - Changing idle stepper settings causes kernel panic #265
 - Data log channel "Fuel: Injection timing SOI" indicates correct values

## May 2023 Release

### Added
 - Detected gear and wastegate position to CAN format
 - Y axis override for Idle VE table. Helps with idle quality on ITB setups. #94
 - Blend tables for boost open and closed loop control #73
 - Log channels to make MegaLogViewer VE Analyze work #82
 - Enable knock sensing on F407 Discovery build, hardcoded to PA3 #105
 - Support gauge and differential fuel pressure sensors (in addition to absolute) #32
 - Snapshot builds have a date code in the folder name #91

### Fixed
 - Sensor checker wasn't checking sensors
 - Removed vestigial warning about unset ignition pins #79
 - Gear detection sometimes didn't work #86
 - Restore built-in INI storage on STM32F7-based ECUs
 - Improve log field names, easier to find the channel you're looking for #98
