Antwort auf: Frühere Trezor-Updates, die alle oder einige der Saatgutwörter erforderten?
As far as I remember, There was one such update related to the bootloader in Trezor One. Update caused Trezor to wipe, and required restoration from seed words. It was somewhere around version ~~1.3.x , but I don’t know which release exactly~~
This one in 1.6.1 (i think)

1.6.3 (i think both 1.6.1 and 1.6.3 wiped but this one is confirmed from official blog)
