Holy mother of pearl! I thought I was crazy for hearing those!!
Interesting. I just checked out the new firmware but didn’t install it yet. The only thing that has changed are the executables.
➜ diff -qr op1_235/ op1_237
Files op1_235/OP1_vdk.ldr and op1_237/OP1_vdk.ldr differ
Files op1_235/te-boot.ldr and op1_237/te-boot.ldr differ
EDIT: I’m curious why they’ve updated the bootloader version from 2.18 to 2.21.
EDIT2: Oh yeah, the bootloader is what shows the firmware version on boot, so they have to update it when the version changes.
