This week’s Rails contributors

14 programmers contributed to Rails this week, two of the them for the first time. If you haven't contributed yet, I hope you will join the list next week.

ActionCable now permits same-origin connections by default

Same-origin connections are now permitted by default. If you want to stick with the old behavior, you can set `config.action_cable.allow_same_origin_as_host = false` 

explain why autosave= disables inverse_of

`autosave` and `inverse_of` do not get along together, since they may for example cause double saves.

Work around read/close race

If one thread calls `close` on an IO at the same time that another calls `read`, segfaults might have occurred. This has now been fixed!

Fixnum and Bignum are deprecated in Ruby trunk

A small upgrade to the Rails codebase to have it ready for the upcoming release of Ruby 2.4 which has deprecated Fixnum and Bignum.

Remove deprecations in Active Model, Action View and Active Job

And in Action Pack too. Methods that were deprecated in Rails 5.0 will be gone once Rails 5.1 ships.
