What's new in VHDL-2002?

[Nicolas Matringe]

Hello all
I've just discovered that ModelSim 5.8c is by default in VHDL-2002 mode.
Is there any reference, any "what's new in VHDL-2002" list somewhere?
I've just made a quick search but didn't find anything interesting.
Thanks in advance

Nicolas,
Not alot. Protected types. Buffer can now connect to
an out port. I think one more, but can't remember.

The current effort, VHDL-200X, does offer significant
changes. For more information see:

Cheers,
Jim

Speaking of protected types:

For my current testing, I connect the test to the testbench components
through queues. I cannot safely simultaneously push and pop the queue
because VHDL '93 doesn't define the behavior of simultaneous accesses to a
shared variable (which I use to store the queue's head and tail access
values). Protected types do just what I need.

Modelsim does not support protected types and I'm upset by their claim to
support VHDL 2002. Apparently IEEE let's vendors claim any compatibility
they please without proof.
