Will the final 1.56 release update the bootloader on older Teensy 4’s and 3’s to 1.07?
I haven't fully decided whether we'll do the 1.07 bootloader update in version 1.56 or hold it back until 1.57. It will definitely still be in 1.56-beta4, coming probably later today (or whenever Arduino 1.8.18 releases).
How can I tell which bootloader version I have?
Teensy Loader shows it in the Help > Verbose Info window.
