Stockholm, September 22 2008

In a bold move today, the Gromacs developers finally decided not to  
wait for Duke Nukem Forever before releasing Gromacs 4.0, and just put  
out release candidate 1 together with a new manual at


"We realize it could be a big disappointment to many users not having  
g_dukenukemforever built-in, but sometimes you have to make hard  
decisions. Had we waited further, we might even have had to release  
Gromacs 5 before Gromacs 4", an anonymous developer said.

If you haven't already been playing around with CVS for the last year  
we think you'll be pretty impressed with the scalability of the new  
code, in addition to full checkpointing support, REMD, and various  

Having said that, since the code has changed a lot we decided to have  
a fairly short cycle of "release candidates" before putting out the  
real version. Please download the code above, try to compile and run  
with it (see manual and html pages in the distro for documentation of  
new stuff), and submit any bugs you find to bugzilla ("If it's not in  
bugzilla, it's not a bug").

Have fun!

Erik, Berk, and David.
