My app is still in development... should I upgrade it to 2.1?

Well, this is probably a pretty straightforward question. I started
developing an app a few weeks ago with Rails 2.0.2, since 2.1 was
still in RC status. The app is still in development, and probably
about a quarter of the way done (mostly just basic CRUD stuff, nothing
major). Since Rails 2.1 has been "officially" released, I'm wondering
if I should upgrade the app to use it now so I can take advantage of a
lot of the things which 2.1 added.

I know that it's usually a bad idea to upgrade blindly to the new
version on a working app, but what about one that you're still in the
development stages of? A few of the Rails 2.1 features I think could
really help some parts of the app, and worse comes to worse if it did
break anything, there isn't anything major going on with it at the
moment.

Thoughts?

I was in the identical position. The files that 2.0.2 and 2.1 generate
are not very different
I generated a blank 2.1 project and used the MELD program, available
in Ubuntu, to diff and merge.
It only took 15 minutes to morph my project to 2.1
I don't think there are many new items that will break much of
anything, mine ran fine.

As always, backup you app before your try this, but it worked great
for me

Good luck

I keep waiting to see a post of anyone upgrading their Windows XP
machine from 2.0.2 to 2.1 ?
Does anyone know an easy way to do this? I've read 'scare stories' of
the new GEMS loading in weird ways.

When I've had weirdness, it was caused by having gems.rubyonrails.org
in my sources list. That source includes beta gems.

Use 'gem environment' to check.

Thoughts?

Probably less of an issue with "vanilla" Rails as opposed to
compatibility with any gems that you use...

I'd say yes. BUT, make sure that all the plugins you use are available for
Rails 2.1. In my case, there are development versions of will_paginate
available for 2.1, but not released versions. So I uninstalled 2.1, though I
could have forced my app to use 2.0. I will be going to 2.1 eventually, but
not today.
