How much is set in stone?

[Jive Dadson]

I'm a newbie at Python, but I've been up to my ears in it for the last
couple of days. -- Considering using it for a scripting language for a
product at work.  I'm very impressed with the system.  Of course there
are things I would like to change. :-)  So the question is, how much is
set in stone at this point?  Is the definition of 2.x now the law of the
land, or can we still make suggestions?
