I see that Teensyduino 1.59 supports the Arduino IDE 2.0.4.
The current Arduino on the Arduino website is 2.3.2. Will the 1.59 version work with the Arduino IDE 2.3.2 or is there a way to get the older of the IDE?
Arduino developers made some nice improvements at version 2.3.0 (especially if using Windows, still good but less needed on Mac and Linux) so definitely use the latest version.
