I haven't been following the RoR community for a while as my work caught up to me, but now things have slowed down a little and I'm looking at getting back to learning Rails for my web app idea (a customized CRM type app for services like lawn care, carpet cleaning and pool cleaning).
As I see, the current version of Ruby 1.9 is 1.9.1-p129. Is Rails compatible with this version? I know from a little reading before that there were issues and upgrading was NOT recommended; has this changed? Any common gems that don't work, or have most of the bugs been ironed out? I already started writing some of my code in Ruby 1.8.7 (Rails 2.3.2) so I'm considering upgrading now to 1.9.1 but I don't want to start an upgrade only to find that a lot of basic things aren't working.
Right now I have both Ruby 1.8.7 and 1.9.1 installed side-by-side on my MacBook just to be on the safe side.
