# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

## 2.1.5 [April 2024]

### Added
- Added support for T3T1
- Added basic support for STM32U5  [#3370]

### Changed
- Speed-up device boot  [#3429]


## 2.1.4 [November 2023]

### Added
- Minimize risk of losing seed when upgrading firmware.  [#2794]
- Support interaction-less upgrade.  [#2919]


## 2.1.3 [September 2023]

### Changed
- Split builds of different parts to use simple util.s assembler, while FW+bootloader use interconnected ones.  [#3205]
- No longer erases seed when firmware is corrupted but firmware header is correct and signed. Added firmware corrupted info to bootloader screen.  [#3122]
- Correctly reinitialize Optiga SE when rebooting.  [#3303]


## 2.1.2 [August 2023]

Internal only release for Model R prototypes.

### Added
- Added support for STM32F429I-DISC1 board  [#2989]
- Locked bootloader support: bootloader will disallow installation of unofficial firmware unless the Optiga pairing secret is erased.
- Support unlocking the bootloader via `UnlockBootloader` message.

### Changed
- Show "empty lock" logo together with model name (replacing the "filled lock" logo for bootloader entirely).  [#3222]
- When building a `PRODUCTION=0` bootloader, it will recognize the development signing keys instead of production ones.

### Fixed
- Fixed gamma correction settings for Model T  [#2955]


## 2.1.1 [June 2023]

Internal only release for Model R prototypes.

### Added
- Added production public keys for T2B1.  [#3048]
- Added UI for T2B1.

### Fixed
- Fix installation of images smaller than 128kB.  [#2941]


## 2.1.0 [April 2023]

### Added
- Optimize touch controller communication  [#262]

- Jump and stay in bootloader from firmware through SVC call reverse trampoline.  [#2284]
- Add RGB LED for Model R  [#2300]
- Using hardware acceleration (dma2d) for rendering  [#2414]
- Add stack overflow detection  [#2427]
- Add model info to image and check when installing/running firmware  [#2623]
- Introduced bootloader emulator.  [#2879]

### Changed
- Update logic of vendor header comparison.  [#1599]
- CPU Frequency increased to 180 MHz  [#2587]
- Fixed display blinking by increasing backlight PWM frequency  [#2595]
