Differences between versions of Ruby on Rails? What should i use?

Question

I first used Rails when it was not so well known in 2005. I experimented with him a little, but he languished due to lack of time.

Now I'm going to repeat the original idea again (with a new implementation), and when researching the latest versions of Ruby and Ruby-on_Rails, I see Ruby 1.9.2 and the beta version of Rails 3.0.

I could not find a brief description of the differences between any of the major versions of Rails. I looked at the official Rails website and several others. There is no joy. Maybe I'm looking in the wrong place or something is wrong?

My project is not commercial (it's a hobby), so the beta version of Rails 3.0 does not distract me. I just wanted to know what the differences are. Can someone please explain?

If this gives any chance of an answer, I will work with the Linux box and / or in the Windows window.

You need to look at the individual structure change logs:

• ActionMailer CHANGELOG
• ActionPack CHANGELOG
• ActiveRecord CHANGELOG
• ActiveResource CHANGELOG
• ActiveSupport CHANGELOG
• Railties CHANGELOG

These are the release blog entries I found on the official Riding Rails blog:

• Rails 3.0 Beta Three (April 2010)
• Rails 3.0: Second Beta (April 2010)
• Rails 3.0 Beta (February 2010)
• Ruby on Rails 2.3.5 released (November 2009)
• Ruby on Rails 2.3.4: Security Fixes (September 2009)
• Rails 2.3.3: Touching, faster JSON, bug fixes (July 2009)
• Rails 2.3: Templates, Engines, Rack, Metal, much more! (March 2009)
• Rails 2.2: i18n, HTTP validators, thread safety, JRuby / 1.9 compatibility, docs (November 2008)
• Rails 2.1.2: Security, Other Fixes (October 2008)
• Rails 2.1.1: many bugs fixed (September 2008)
• Rails 2.0: It's Done! (December 2007)
• Ruby on Rails 1.2.6: Security and Maintenance Release (November 2007)
• Rails 1.2.5: Security and Service Release (October 2007)
• Rails 1.2.4: Service Release (October 2007)
• Rails 1.2.3: Compatible with Ruby 1.8.6 (and other fixes) (March 2007)
• Rails 1.2.2: SQLite3, Gems, Unique Resources (February 2007)

Happy reading!

Generally use the stable release of latests. Rails is currently 2.3.5. I would not learn Rails with Rails 3.0 beta X, and if you have not touched Rails in 5 years, you are almost starting from scratch.

After the release of Rails 3.0, you can upgrade. For commercial projects, I do not collect it yet.

As for Ruby 1.8 vs. 1.9, I don't have a strong opinion, you can use it. I heard that 1.9 is not yet stable.

With Rails 3, you'll probably miss a lot of plugins ...
