A new release of Arduino IDE 2.x is now available for download here:
https://www.arduino.cc/en/software#experimental-software
This release adds two important features to the new IDE.
Firmware and certificate update tools
You will find the Tools > WiFi101 / WiFiNINA Firmware Updater menu item you may be accustomed to using in the classic Arduino IDE for updating the Wi-Fi radio firmware on Arduino boards.
In addition to a nicer UI, the Arduino IDE 2.x's tool has the capability to download firmwares from the Internet. So the full list of available versions will always be available!
The certificate uploader tool is now available via Tools > Upload SSL Root Certificates in the IDE's menus.
Manually installed platforms
Manually installed Arduino boards platforms are now supported.
Although the existing Boards Manager feature is the best way to install and update release versions of boards platforms, the hardware
subfolder of the sketchbook is a convenient place to store platforms used for development, beta testing, and experimentation.
These will now be recognized by Arduino IDE 2.x just the same as the classic IDE.
