Slavek I'm using Stretch with your PSB repo and keep it up to date each day (today's update was 104 packages from Debian) and binutils will not update without removing many (currently 44) TDE packages. Packages listed here for your perusal. If you have no other DEs updating binutils breaks TDE in Stretch and makes it unusable.
