Which version of Rails do you recommend if I start a new project using
RoR?
I studied RoR with Agile Web Development with Rails (1st edition) last
year, and found that there is new version 2.x out there - but, it was
very hard for me to find any book for Rails 2.0.
Do I have to stick with 1.x version of Rails?
Also, I wonder if the rails hosting companies do support the latest
version of Rails as well.
The latest Rails is always the best to start out with. We often try to
follow along Rails Edge during our heavy development cycle so that
we're not spending too much time handling upgrades later on.
Definitely move to the latest, and grab a copy of Simply Rails 2 if
you are interested. A great, easy read which should guide you rather
well through some of the changes between Rails 1.x and 2.x.
