Rails 5.2.0 RC2 Notes - http://weblog.rubyonrails.org/2018/3/20/Rails-5-2-RC2/ Rails 5.2.0 Release Notes - http://edgeguides.rubyonrails.org/5_2_release_notes.html

Active Storage

With the new Active Storage framework in Rails 5.2, we’ve solved for the modern approach of uploading files straight to the cloud. Out of the box, there’s support for Amazon’s S3, Google’s Cloud Storage, and Microsoft Azure Cloud File Storage.

If you’re dealing with images, you can create variants on the fly. If you’re dealing with videos or PDFs, you can create previews on the fly. And regardless of the type, you can analyze uploads for metadata extraction asynchronously.

Redis Cache Store

Redis for general partial, fragment, and other Rails caching jobs.

The Redis cache store takes advantage of Redis support for automatic eviction when it reaches max memory, allowing it to behave much like a Memcached cache server.

Deployment note: Redis doesn't expire keys by default, so take care to use a dedicated Redis cache server. Don't fill up your persistent-Redis server with volatile cache data! Read the Redis cache server setup guide in detail.

Encrypted Secrets (Credentials)

Added config/credentials.yml.enc file to store production app secrets. It allows saving any authentication credentials for third-party services directly in repository encrypted with a key in the config/master.key file or the RAILS_MASTER_KEY environment variable. This will eventually replace Rails.application.secrets and the encrypted secrets introduced in Rails 5.1. Furthermore, Rails 5.2 opens API underlying Credentials, so you can easily deal with other encrypted configurations, keys, and files.

Content Security Policy

The HTTP Content-Security-Policy response header allows web site administrators to control resources the user agent is allowed to load for a given page. With a few exceptions, policies mostly involve specifying server origins and script endpoints. This helps guard against cross-site scripting attacks (XSS).

Rails 5.2 ships with a new DSL that allows you to configure a Content Security Policy for your application. You can configure a global default policy and then override it on a per-resource basis and even use lambdas to inject per-request values into the header such as account subdomains in a multi-tenant application. You can read more about this in the Securing Rails Applications guide.
