## Mobly Release 1.10: Framework and `AndroidDevice` Output Improvements

*This is likely the last major release that preserves Py2 compatibility.*

### New
* `AndroidDevice` now has a new `is_emulator` property.
* Better multi-user support in `AndroidDevice`.
* Standardized logging and output file names.
* Improvement in `utils.concurrent_exec`.
* Support class-based decorator on Mobly test methods.

### Breaking Changes
Due to the standardization of output files for both Mobly and `AndroidDevice`
controller, if you have custom parser of Mobly outputs, you need to adjust
your parsing logic to accommodate the changes.

* Major change in output directory structure #650
* Names of `AndroidDevice`'s output files have been standardized #633
* Changed multiple references of `test_bed` to `testbed` in code #641

## Mobly Release 1.9: UID Support; `AndroidDevice` and General Runner Improvements

### New
* Support specifying Unique Identifier (UID) for both static and generated test
  methods.

### Breaking Changes

  was never used.

  including `AndroidDevice#load_sl4a`.

### Fixes
* Bug fixes and reliability improvements in `AdbProxy`.
* Improved APIs for taking bugreports
* Improvements in `AndroidDevice` service management
* Improvements in `AndroidDevice`'s `getprop` calls, including caching.

## Mobly Release 1.8.1: Fix Final Cleanup Stage Error Capture

### Fixes
* Errors from the final clean up stage are now properly recorded.
  * NOTE: This may expose errors that have long existed in your tests. They are
    usually caused by your test interrupting controller object life cycle
    management. Fixing these issues would help keep your test env clean.
* Fixed docs config so `http://mobly.readthedocs.io` show all the classes
  properly.


## Mobly Release 1.8: Controller Management and `AndroidDevice` Service

### New
* Modularized controller management logic by introducing `ControllerManager`.
* Introduced the service mechanism in `AndroidDevice`, life cycles management
  of long-running processes for Android devices.

  `logcat.create_per_test_excerpt`.
* `AdbError` now has `serial` as a direct attribute.

### Deprecated
The following APIs in `AndroidDevice` are deprecated:
* `start_services` -> `ad.services.start_all`
* `stop_services` -> `ad.services.stop_all`
* `start_adb_logcat` -> `ad.services.logcat_start`
* `stop_adb_logcat` -> `ad.services.logcat_stop`

### Fixes
* `expects` APIs crashing in certain execution stages.
