\- Release Candidate 1.5.0

\*New Features\*

\- Numeric metrics
\- Client-side programmatic forced variations.

\*Bug Fixes\*

\- Remove Espresso dependency
\- Narrow proguard rules
\- Last modified fixed so that multiple project files can be used.
\- Call start listener if there is an exception.
\- Example of overriding Gson and android-logger in test-app gradle file.
\- Fix crash on API 17 (missing annotation).
\- Support for Android O (please see developer docs for details). Basically, Android O and above will use JobScheduler and pre Android O will continue to use AlarmService. This is done through a class called the JobWorkService which allows you to keep your Service and IntentService intact. Developers can piggyback on this method and keep thier IntentServices and use the JobWorkService.

\*Breaking Changes\*

\- Same as 1.4.0 see below.
\- Need to add permissions to both receivers in your manifest if you plan on using the EventRescheduler or the DatafileRescheduler (see test\_app manifest for example) [https://github.com/optimizely/android-sdk/blob/master/test-app/src/main/AndroidManifest.xml](https://github.com/optimizely/android-sdk/blob/master/test-app/src/main/AndroidManifest.xml)
