Changelog

All notable changes to the Raspberry Pi system images will be documented in here. This is a collection of the changes to the AstroPlant core software and changes to the operating system we provide.

[1.0.0b8.1] - 2022-09-09

This release fixes a regression introduced in 1.0.0b8.

AstroPlant Software

Peripherals

## [1.0.0b8] - 2022-09-09

### Fix

- DHT22: wait for measurement (regression introduced in 1.0.0b7)

[1.0.0b8] - 2022-09-09

This release focuses on increasing the stability of the kit. Errors when communicating with peripherals are handled better.

System

• Upgrade operating system to Raspberry Pi OS Bullseye

• Move to libcamera-based camera stack

• Fix hotspot image to include a default country code when setting up WiFi. This currently defaults to NL, which should be fine in most of Europe, but radio frequency regulations in your country may require you to manually set the correct country code in /etc/wpa_supplicant/wpa_supplicant.conf
