Looks like a solid and and relatively straightforward upgrade from Rails 4.2. It's hard not to feel Rails has become a bit of a slow-moving behemoth though, with this release four years after 4.0.

unfortunately, i agree with you. Ive moved to elixir for all web work and the erlang vm just blows ruby out of the water at restapi/web services stuff. Im a huge ruby/rails fan though, and have earned a living off the ruby ecosystem. I just dont see how ruby can overcome the vm disadvantage to be honest, though id really like to see them try

They don't have to. With a good architecture (caching, etc) Rails scales well in the overwhelming majority of cases. Performance is only one of many things to worry about when choosing a technology.

Looks like now's a good time to mention that the Ruby on Rails Tutorial book has already been updated for Rails 5:

http://railstutorial.org/book

Sales actually just launched on Tuesday (announcement here: https://news.learnenough.com/rails-5-edition-of-rails-tutori...), and you can pick up your copy of the new 4th edition here:

http://railstutorial.org/code/launch

That link includes a 20% launch discount, which expires tonight at midnight PDT.

As with previous versions, the new edition focuses on the core principles of web development, so there isn't much Rails 5–specific material in the update, but I am planning standalone Learn Enough tutorials on things like Action Cable and Rails API (http://learnenough.com/).

Been using Elixir / Phoenix as well, and it's been a breath of fresh air. That said, I'm glad that rails has been looking at projects like Phoenix for inspiration as it continues to grow and adapt.

I'm glad that rails has been looking at projects like Phoenix for inspiration Other way around. Phoenix was explicitly inspired by Rails and founded by Rails core members. Elixir was first created by a Rails core member. Phoenix is the performance-really-matters successor to Rails.

Some of the features of TurboLinks 5 are inspired by things Phoenix did with it's channels, I think

I just dont see how ruby can overcome the vm disadvantage to be honest I don't know how mature it is, but couldn't jruby be the answer to this?

I use jRuby, which is great and an amazing piece of engineering. However, with Rails, you're only see about a 20% speed bump and out of the box it uses too much memory to run on Heroku's free tier. You'll also miss out on the gems with c extensions (for now I think that's about to change). Additionally, there seems to be a performance regression around includes and case statements. Your devops story can also be a bit trickier, depending upon what you're experienced with. I like jRuby a lot, but it's a mixed bag for the moment.

We've moved all of our backend offerings from Rails to Elixir/Phoenix. Despite some questioning the value of anything below 100ms response times there is a lot of data backing up the idea that Elixir/Phoenix can lead to a more maintainable and more economical solution.

I find working with functional languages and type systems (w/ dialyzer in this case) makes my projects more maintainable in general. Might just be a personal bias towards them though. Note: I haven't used Phoenix but I'm a fan of Erlang.

I think most folks are finding that distribution in an erlang based application is a lot simpler, because you don't need to pull in things like redis for pubsub, memcached for caching, etc etc. erlang solves a bunch of problems in a rather elegant way that are solved in the java/python/ruby world through gobs of duct tape.

Ruby 3x3 is a plan to make Ruby 3 times faster than Ruby 2.x. Here's some further reading:

I've been following along with Rails 5 for many months now and I've been tracking progress on updating GitLab in our issue tracker[1].

Feel free to look at the relevant merge requests and use them as guides to upgrade your own apps :) We're still on 4.2.6 since we have a few gems we're waiting on, but I hope to change that in a month or two!

Favorite features are probably the various performance improvements and underlying improvements to the framework, as well as quiet_assets being moved into sprockets-rails.

I also wanted to give a shoutout to BigBinary's Rails 5 series, since it's been great for finding out about new features[2].
