Rodrigo, rails-core is more for discussion about features. If you're

Thanks, Steve.
I could finally upgrade my Rails application and I must say it is much
faster on Ruby 2 + Rails 4 beta 1 and it wasn't a painful process
either. I just found a few bugs that I was able to work-around:
https://github.com/rails/rails/issues/9449
For the bug above I just had to reorder some routes until it is fixed on
master.
I've experienced another bug that I haven't created a issue for because
I can't reproduce it. For some reasons, some CSS image-url paths were
being generated incorrectly missing the leading "/assets" and rendering
as "/fields/.." instead of "/assets/fields/...". I somewhat added a new
rule to the SCSS class to add some "background-image:
image-path('fields/...')" and then all url paths have been fixed. Then I
removed the newly inserted line so that the file was exactly like the
original one and the CSS kept rendered correctly. Sorry, I have no idea
why that happened but it happened multiple times to assets in different
gems.
The Ruby part was the easiest in the upgrade process. I had to upgrade
lots of gems and use 'devise' from the 'rails4' branch, fix the
dependency for my own rails-sandbox-assets gem and release it, fork
knockoutjs-rails and fix it:
https://github.com/jswanner/knockoutjs-rails/pull/3
My Ruby specs only failed due to some config changes in
config/environment**/*.rb. I created a new Rails app and based the new
configs on the new generated one. After that my Ruby specs all passed
without any modification. Sadly that wasn't the case for my JavaScript
specs...
Certainly the most time consuming task was to port my client-side code
to jQuery 1.9. It is a bit sad that Rails 4 will force you to upgrade
jQuery if you're using jquery-rails, but that's ok. At least most of my
client-side code is in the Grails application of the overall application
I maintain. I'll have more time to upgrade to jQuery 1.9 for most of the
scripts :)
Thank you very much for this release. I'm not sure if it is due to Ruby
2, Rails 4, or both, but my feeling is that the application is
responding much faster, at least in development mode.
Unfortunately I can't deploy it on Ruby 2 yet because there is a bug
that will prevent me to use the bson_ext gem in Ruby 2.0.0-p1. For some
reason it generates a "ext/bson_ext/bson_ext" instead of
"ext/bson_ext/cbson.so" (although a diff will reveal they're the same
file) like it is the case for Ruby 1.9.3. But for development mode, that
is ok to use Ruby 2 as it will fallback to the Ruby implementation that
isn't that slow, at least, for development purposes.
Cheers,
Rodrigo.
