New Stuff

Drop indexes concurrently in PostgreSQL

Now you can drop PostgreSQL indices concurrently in Rails 5, just like how you can already add indices concurrently today.

Approachable SSL handling

Remember good ‘ol config.force_ssl? You can now use it with greater control. With improvements in SSL redirect and better handling of Strict Transport Security, you will surely love this improved version of config.force_ssl.

Mult-context validations

Ever faced the need of running validations of create and update contexts both at the same time? Now you can do that by passing multiple contexts to the #valid? and #invalid? methods.

Improved

Active Record performance improvements

This week lot of work was done for improving Active Record internals by reducing object allocations, avoid creating relations when not required and so on. Kudos to @tgxworld!

Prepared statements with MySQL

Rails now supports latest version of mysql2 gem. Is this a big deal? Yes!! You can now use prepared statements using this version. Now that’s awesome!

Improve sql logging coloration

If you are using custom SQL queries with Ruby herredoc, you will be able to identify them instantly in your logs. Why? Because they will have better colors thanks to this patch.

Not just that, overall coloration of all SQL queries is improved here as well!

Reaching into the cookie jar

The cookie-handling code in Rails is one of the more complicated code in the framework, largely due to the need to support and migrate legacy cookies produced by older versions of Rails.

Kasper refactored some of those code to make it less hostile to future improvements, nice!

Fixed

Generator errors messages will be in plain English

If you have seen some weird characters showing up in error messages of rails g commands due to localization of some messages, it is now fixed!
