## Rails 6.0.0.beta2 (February 25, 2019) ##
* Fix date value when casting a multiparameter date hash to not convert
from Gregorian date to Julian date.
Before:
Day.new({"day(1i)"=>"1", "day(2i)"=>"1", "day(3i)"=>"1"})
=> #<Day id: nil, day: "0001-01-03", created_at: nil, updated_at: nil>
After:
Day.new({"day(1i)"=>"1", "day(2i)"=>"1", "day(3i)"=>"1"})
=> #<Day id: nil, day: "0001-01-01", created_at: nil, updated_at: nil>
Fixes #28521.

* Fix year value when casting a multiparameter time hash.
When assigning a hash to a time attribute that's missing a year component
(e.g. a `time_select` with `:ignore_date` set to `true`) then the year
defaults to 1970 instead of the expected 2000. This results in the attribute
changing as a result of the save.
Before:
```
event = Event.new(start_time: { 4 => 20, 5 => 30 })
event.start_time # => 1970-01-01 20:30:00 UTC
event.save
event.reload
event.start_time # => 2000-01-01 20:30:00 UTC
```
After:
```
event = Event.new(start_time: { 4 => 20, 5 => 30 })
event.start_time # => 2000-01-01 20:30:00 UTC
event.save
event.reload
event.start_time # => 2000-01-01 20:30:00 UTC
```

## Rails 6.0.0.beta1 (January 18, 2019) ##
* Add `ActiveModel::Errors#of_kind?`.
*bogdanvlviv*, *Rafael Mendonça França*
* Fix numericality equality validation of `BigDecimal` and `Float`
by casting to `BigDecimal` on both ends of the validation.
*Gannon McGibbon*
* Add `#slice!` method to `ActiveModel::Errors`.
*Daniel López Prat*
* Fix numericality validator to still use value before type cast except Active Record.
Fixes #33651, #33686.
*Ryuta Kamizono*
* Fix `ActiveModel::Serializers::JSON#as_json` method for timestamps.
Before:
```
contact = Contact.new(created_at: Time.utc(2006, 8, 1))
contact.as_json["created_at"] # => 2006-08-01 00:00:00 UTC
```
After:
```
contact = Contact.new(created_at: Time.utc(2006, 8, 1))
contact.as_json["created_at"] # => "2006-08-01T00:00:00.000Z"
```
*Bogdan Gusiev*
* Allows configurable attribute name for `#has_secure_password`. This
still defaults to an attribute named 'password', causing no breaking
change. There is a new method `#authenticate_XXX` where XXX is the
configured attribute name, making the existing `#authenticate` now an
alias for this when the attribute is the default 'password'.
Example:
class User < ActiveRecord::Base
has_secure_password :recovery_password, validations: false
end
user = User.new()
user.recovery_password = "42password"
user.recovery_password_digest # => "$2a$04$iOfhwahFymCs5weB3BNH/uX..."
user.authenticate_recovery_password('42password') # => user
*Unathi Chonco*
* Add `config.active_model.i18n_full_message` in order to control whether
the `full_message` error format can be overridden at the attribute or model
level in the locale files. This is `false` by default.
*Martin Larochelle*
* Rails 6 requires Ruby 2.5.0 or newer.
*Jeremy Daer*, *Kasper Timm Hansen*
