Java has plenty deprecated stuff. So does *cough* php. So do other 
languages. That alone is not an indication of anything except of the 
on-going development. There are always references to (usually) better 
replacements.

There are still cases of simple renaming  to make functions follow the 
convention, but these ones are easily fixed with find/replace.

I'd just keep certain version of the compiler & phobos + libs that are 
needed. And then when deadlines are passed do some refactoring/tweaking 
to bump used versions up a notch. I agree that it's far from ideal.

The deprecated APIs do still work if you use the -d switch. What is far 
more shattering are compiler changes (and bugfixes, sadly) given that 
2.051 is 9 versions behind he latest it won't surprise me that it breaks 
a _lot_.

Problem is these frameworks also have certain version requirement last 
time I checked it goes like this: requires  php 5.3+ or say python 2.5+ 
  etc.

So we'd better have certain D versions that are more lasting. But 
that'll make sense once the feature set is fully implemented and polished.

Anyway see D stable topic.
