Today, I received my new PBP 2.50 on CD and a new printed manual. Each part cost several Euros.

But again - the documentation is lousy !
On melabs website there is the version history with
"Adds Define to disable/enable interrupts for Write."

But, where the hell is the documentation to use this feature ?
You must look inside the *.libs ...

Next time I will begin a new project - with swordfish !
