## [1.0.0] - pre 2022-05-10
First (more or less) working version.
## [1.0.1] - 2022-05-10
### Added
- Support for saving settings to internal FLASH
## [1.0.2] - 2022-05-11
### Added
- APRS settings can now be saved in FLASH
- logging to serial USB is disabled when in KISS mode (but KISS mode still needs to be implemented)
## [1.0.3] - 2022-05-12
### Added
- All settings (LoRa and APRS) can now be saved to FLASH.
- Command added for restarting LoRa radio when settings are alterred: "restart lora"
- Received LoRa frames can now be converted to proper AX25 frames (needed for KISS TNC functionality)
- KISS mode works for receiving (LoRa -> USB port)
- KISS mode for transmitting in early phase of development
- Can enter KISS mode with command "kiss 1" and exit KISS mode with command "sudo kissparms -p ax0 -x"
## [1.0.4] - 2022-05-13
### Added
- Fully functioning KISS TNC, but repeater flag could not be tested because LoRa APRS software in general is a mess. It appears that nobody reads the AX.25 standard anymore. This software probably is also not up to spec. But at least I tried! You should too: [http://www.ax25.net/AX25.2.2-Jul%2098-2.pdf](http://www.ax25.net/AX25.2.2-Jul%2098-2.pdf)
## [1.0.5] - 2023-12-19
### Changed
- Nothing changed, last version without telemetry. Tagged for archiving purposes.
## [1.1.0] - 2023-12-19
### Added
- PE1RXF telemetry
- I2C support
- I2C driver for AM2315 temperature/humidity sensor
### Fixed
- Struct for saving settings to FLASH is now 256 bytes excactly (problem with padding done by the compiler)
## [1.1.1] - 2023-12-19
### Fixed
- One of the digital outputs was inverted.
## [1.1.2] - [2024-01-08]
### Fixed
- Negative temperature where converted wrong: -1 became -32767. This was because of a weird format the sensor uses.
