## Rails 6.0.0.beta2 (February 25, 2019) ##
* Fix non-symbol access to nested hashes returned from `Rails::Application.config_for`
being broken by allowing non-symbol access with a deprecation notice.
*Ufuk Kayserilioglu*

*Gannon McGibbon*
## Rails 6.0.0.beta1 (January 18, 2019) ##
* Remove deprecated `after_bundle` helper inside plugins templates.
*Rafael Mendonça França*
* Remove deprecated support to old `config.ru` that use the application class as argument of `run`.
*Rafael Mendonça França*
* Remove deprecated `environment` argument from the rails commands.
*Rafael Mendonça França*
* Remove deprecated `capify!`.
*Rafael Mendonça França*
* Remove deprecated `config.secret_token`.
*Rafael Mendonça França*
* Seed database with inline ActiveJob job adapter.
*Gannon McGibbon*
* Add `rails db:system:change` command for changing databases.
```
bin/rails db:system:change --to=postgresql
force config/database.yml
gsub Gemfile
```
The change command copies a template `config/database.yml` with
the target database adapter into your app, and replaces your database gem
with the target database gem.
*Gannon McGibbon*
* Add `rails test:channels`.
*bogdanvlviv*
* Use original `bundler` environment variables during the process of generating a new rails project.
*Marco Costa*
* Send Active Storage analysis and purge jobs to dedicated queues by default.
Analysis jobs now use the `:active_storage_analysis` queue, and purge jobs
now use the `:active_storage_purge` queue. This matches Action Mailbox,
which sends its jobs to dedicated queues by default.
*George Claghorn*
* Add `rails test:mailboxes`.
*George Claghorn*
* Introduce guard against DNS rebinding attacks.
The `ActionDispatch::HostAuthorization` is a new middleware that prevents
against DNS rebinding and other `Host` header attacks. It is included in
the development environment by default with the following configuration:
Rails.application.config.hosts = [
IPAddr.new("0.0.0.0/0"), # All IPv4 addresses.
IPAddr.new("::/0"), # All IPv6 addresses.
"localhost" # The localhost reserved domain.
]
In other environments `Rails.application.config.hosts` is empty and no
`Host` header checks will be done. If you want to guard against header
attacks on production, you have to manually permit the allowed hosts
with:
Rails.application.config.hosts << "product.com"
The host of a request is checked against the `hosts` entries with the case
operator (`#===`), which lets `hosts` support entries of type `RegExp`,
`Proc` and `IPAddr` to name a few. Here is an example with a regexp.
# Allow requests from subdomains like `www.product.com` and
# `beta1.product.com`.
Rails.application.config.hosts << /.*\.product\.com/
A special case is supported that allows you to permit all sub-domains:
# Allow requests from subdomains like `www.product.com` and
# `beta1.product.com`.
Rails.application.config.hosts << ".product.com"
*Genadi Samokovarov*
* Remove redundant suffixes on generated helpers.
*Gannon McGibbon*
* Remove redundant suffixes on generated integration tests.
*Gannon McGibbon*
* Fix boolean interaction in scaffold system tests.
*Gannon McGibbon*
* Remove redundant suffixes on generated system tests.
*Gannon McGibbon*
* Add an `abort_on_failure` boolean option to the generator method that shell
out (`generate`, `rake`, `rails_command`) to abort the generator if the
command fails.
*David Rodríguez*
* Remove `app/assets` and `app/javascript` from `eager_load_paths` and `autoload_paths`.
*Gannon McGibbon*
* Use Ids instead of memory addresses when displaying references in scaffold views.
Fixes #29200.
*Rasesh Patel*
* Adds support for multiple databases to `rails db:migrate:status`.
Subtasks are also added to get the status of individual databases (eg. `rails db:migrate:status:animals`).
*Gannon McGibbon*
* Use Webpacker by default to manage app-level JavaScript through the new app/javascript directory.
Sprockets is now solely in charge, by default, of compiling CSS and other static assets.
Action Cable channel generators will create ES6 stubs rather than use CoffeeScript.
Active Storage, Action Cable, Turbolinks, and Rails-UJS are loaded by a new application.js pack.
Generators no longer generate JavaScript stubs.
*DHH*, *Lachlan Sylvester*
* Add `database` (aliased as `db`) option to model generator to allow
setting the database. This is useful for applications that use
multiple databases and put migrations per database in their own directories.
```
bin/rails g model Room capacity:integer --database=kingston
invoke active_record
create db/kingston_migrate/20180830151055_create_rooms.rb
```
Because rails scaffolding uses the model generator, you can
also specify a database with the scaffold generator.
*Gannon McGibbon*
* Raise an error when "recyclable cache keys" are being used by a cache store
that does not explicitly support it. Custom cache keys that do support this feature
can bypass this error by implementing the `supports_cache_versioning?` method on their
class and returning a truthy value.
*Richard Schneeman*
* Support environment specific credentials overrides.
So any environment will look for `config/credentials/#{Rails.env}.yml.enc` and fall back
to `config/credentials.yml.enc`.
The encryption key can be in `ENV["RAILS_MASTER_KEY"]` or `config/credentials/production.key`.
Environment credentials overrides can be edited with `rails credentials:edit --environment production`.
If no override is set up for the passed environment, it will be created.
Additionally, the default lookup paths can be overwritten with these configs:
- `config.credentials.content_path`
- `config.credentials.key_path`
*Wojciech Wnętrzak*
* Make `ActiveSupport::Cache::NullStore` the default cache store in the test environment.
*Michael C. Nelson*
* Emit warning for unknown inflection rule when generating model.
*Yoshiyuki Kinjo*
* Add `database` (aliased as `db`) option to migration generator.
If you're using multiple databases and have a folder for each database
for migrations (ex db/migrate and db/new_db_migrate) you can now pass the
`--database` option to the generator to make sure the the migration
is inserted into the correct folder.
```
rails g migration CreateHouses --database=kingston
invoke active_record
create db/kingston_migrate/20180830151055_create_houses.rb
```
*Eileen M. Uchitelle*
* Deprecate `rake routes` in favor of `rails routes`.
*Yuji Yaginuma*
* Deprecate `rake initializers` in favor of `rails initializers`.
*Annie-Claude Côté*
* Deprecate `rake dev:cache` in favor of `rails dev:cache`.
*Annie-Claude Côté*
* Deprecate `rails notes` subcommands in favor of passing an `annotations` argument to `rails notes`.
The following subcommands are replaced by passing `--annotations` or `-a` to `rails notes`:
- `rails notes:custom ANNOTATION=custom` is deprecated in favor of using `rails notes -a custom`.
- `rails notes:optimize` is deprecated in favor of using `rails notes -a OPTIMIZE`.
- `rails notes:todo` is deprecated in favor of using`rails notes -a TODO`.
- `rails notes:fixme` is deprecated in favor of using `rails notes -a FIXME`.
*Annie-Claude Côté*
* Deprecate `SOURCE_ANNOTATION_DIRECTORIES` environment variable used by `rails notes`
through `Rails::SourceAnnotationExtractor::Annotation` in favor of using `config.annotations.register_directories`.
*Annie-Claude Côté*
* Deprecate `rake notes` in favor of `rails notes`.
*Annie-Claude Côté*
* Don't generate unused files in `app:update` task.
Skip the assets' initializer when sprockets isn't loaded.
Skip `config/spring.rb` when spring isn't loaded.
Skip yarn's contents when yarn integration isn't used.
*Tsukuru Tanimichi*
* Make the master.key file read-only for the owner upon generation on
POSIX-compliant systems.
Previously:
$ ls -l config/master.key
-rw-r--r-- 1 owner group 32 Jan 1 00:00 master.key
Now:
$ ls -l config/master.key
-rw------- 1 owner group 32 Jan 1 00:00 master.key
Fixes #32604.
*Jose Luis Duran*
* Deprecate support for using the `HOST` environment variable to specify the server IP.
The `BINDING` environment variable should be used instead.
Fixes #29516.
*Yuji Yaginuma*
* Deprecate passing Rack server name as a regular argument to `rails server`.
Previously:
$ bin/rails server thin
There wasn't an explicit option for the Rack server to use, now we have the
`--using` option with the `-u` short switch.
Now:
$ bin/rails server -u thin
This change also improves the error message if a missing or mistyped rack
server is given.
*Genadi Samokovarov*
* Add "rails routes --expanded" option to output routes in expanded mode like
"psql --expanded". Result looks like:
```
$ rails routes --expanded
--[ Route 1 ]------------------------------------------------------------
Prefix | high_scores
Verb | GET
URI | /high_scores(.:format)
Controller#Action | high_scores#index
--[ Route 2 ]------------------------------------------------------------
Prefix | new_high_score
Verb | GET
URI | /high_scores/new(.:format)
Controller#Action | high_scores#new
```
*Benoit Tigeot*
* Rails 6 requires Ruby 2.5.0 or newer.
