## v0.7.0
**This version has breaking changes**

* Experiment can now specify multiple qualify blocks
  * `Verdict::Experiment#qualifier` has been removed in favor for `Verdict::Experiment#qualifiers`, which returns an array of procs
* Allow pass of an argument to qualify with a method name as a symbol, instead of a block

## v0.6.3

* Fix bug were Verdict.directory is overwritten
* Allow Verdict.directory to handle multiple directories (using globbing)

## v0.6.2

* Implement Verdict.clear_repository_cache, which fixes autoloading issues with Rails.
* Integrated Verdict.clear_repository_cache with our Railtie.

## v0.6.1

* Make Verdict Railtie `.freeze` the eager_load_paths it changes as Rails itself does.

## v0.6.0

### Verdict::Experiment
* replaced following public methods that took a `subject_identifier` with an equivalent method which takes a `subject`

| old method                                                      | new method                               |
| --------------------------------------------------------------- | ---------------------------------------- |
| `lookup_assignment_for_identifier(subject_identifier)`          | `lookup(subject)`                        |
| `assign_manually_by_identifier(subject_identifier, group)`      | `assign_manually(subject, group)`        |
| `disqualify_manually_by_identifier(subject_identifier)`         | `disqualify_manually(subject)`           |
| `remove_subject_assignment_by_identifier(subject_identifier)`   | `remove_subject_assignment(subject)`     |
| `fetch_assignment(subject_identifier)`                          | `lookup(subject)`                        |

* Changed the following methods to take a `subject` instead of `subject_identifier`
 * `subject_assignment(subject, group, originally_created_at = nil, temporary = false)`
 * `subject_conversion(subject, goal, created_at = Time.now.utc)`

#### Improved Testability
`Verdict::Experiment#subject_qualifies?(subject, context = nil)` is now public, so it's easier to test
the qualification logic for your experiments.

### Verdict::BaseStorage
* `BaseStorage`'s public methods now take a `subject`, instead of a `subject_identifier`. They fetch the `subject_identifier` using the `Experiment#subject_identifier(subject)` method. Existing storages **will still work normally**.
* The basic `#get`,`#set`, and `#remove` methods are now protected.

### Verdict::Assignment
* `#initialize` now takes a `subject` instead of a `subject_identifier`, the new signature is `initialize(experiment, subject, group, originally_created_at, temporary = false)`

### Verdict::Conversion
* `#initialize` now takes a `subject` instead of a `subject_identifier`, the new signature is `initialize(experiment, subject, goal, created_at = Time.now.utc)`

### Rake Tasks
* In order to use the included helper Rake Tasks, you must implement `fetch_subject(subject_identifier)` in `Experiment`.
