Book recommendation

[Maciej Sobczak <no.spam@no.spam.com>]

Hi,

I'm a computer programmer with C++ experience. Currently I work in the 
real-time environment and I would like to broaden my perspective on 
languages and tools that can be effectively used in the area of 
real-time, distributed and concurrent programming.

Note that very likely I will *not* be using Ada professionally.

There are two books that I found and that I think would help me:

- Programming in Ada 95 (Barnes)
- Concurrency in Ada (Barns)

I learned that Ada community is preparing for the new standard release 
this year.

My questions are:
- Would you recommend these two books (which focus on Ada95) anyway?
- Are there any changes planned in the *relevant* parts of the language 
that would render these two books outright obsolete?
- Or maybe there are new editions planned for later this year (I don't 
mind waiting)?

Regards,
