Changes in this update:
**Enhancements**
* Added the `ExternalMediaPlayer` Capability Agent. This allows playback from music providers that control their own playback queue. Example: Spotify.
* Added support for AU and NZ to the `SampleApp`.
* Firmware version can now be sent to Alexa via the `SoftwareInfo` event. The firmware version is specified in the config file under the `sampleApp` object as an integer value named [`firmwareVersion`](https://github.com/alexa/avs-device-sdk/blob/master/Integration/AlexaClientSDKConfig.json#L52).
* The new `f` command was added to the `SampleApp` which allows the firmware version to be updated at run-time.
* Optional configuration changes have been introduced. Now a [default log level](https://github.com/alexa/avs-device-sdk/blob/master/Integration/AlexaClientSDKConfig.json#L93) can be set for `ACSDK_LOG_MODULE` components, globally or individually. This value is specified under a new root level configuration object called `logger`, and the value itself is named `logLevel`. This allows you to limit the degree of logging to that default value, such as `ERROR`or `INFO`.
**Bug Fixes**
* Fixed bug where `AudioPlayer` progress reports were not being sent, or were being sent incorrectly.
* [Issue 408](https://github.com/alexa/avs-device-sdk/issues/408) - Irrelevant code related to `UrlSource` was removed from the `GStreamer-based MediaPlayer` implementation.
* The `TZ` variable no longer needs to be set to `UTC` when building the `SampleApp`.
* Fixed a bug where `CurlEasyHandleWrapper` logged unwanted data on failure conditions.
* Fixed a bug to improve `SIGPIPE` handling.
* Fixed a bug where the filename and classname were mismatched. Changed `UrlToAttachmentConverter.h` to `UrlContentToAttachmentConverter.h`,and `UrlToAttachmentConverter.cpp` to `UrlContentToAttachmentConverter.cpp`
**Known Issues**
* The `ACL` may encounter issues if audio attachments are received but not consumed.
* Display Cards for Kindle don't render.
* If using the GStreamer-based `MediaPlayer` implementation, after muting and un-muting an audio item, the next item in the queue will begin playing rather than continuing playback of the originally muted audio item.
* `SpeechSynthesizerState` currently uses `GAINING_FOCUS` and `LOSING_FOCUS` as a workaround for handling intermediate state. These states may be removed in a future release.
* Music playback doesn't immediately stop when a user barges-in on iHeartRadio.
Changes in this update
* **Enhancements**
* Updated MediaPlayer to solve stability issues
* All capability agents were refined to work with the updated MediaPlayer
* Added the TemplateRuntime capability agent
* Added the SpeakerManager capability agent
* Added a configuration option ("sampleApp":"endpoint") that allows the endpoint that SampleApp connects to to be specified without changing code or rebuilding
* Added very verbose capture of libcurl debug information
* Added an observer interface to observer audio state changes from AudioPlayer
* Added support for StreamMetadataExtracted Event. Stream tags found in the stream are represented in JSON and sent to AVS
* Added to the SampleApp a simple GuiRenderer as an observer to the TemplateRuntime Capability Agent
* Moved shared libcurl functionality to AVSCommon/Utils
* Added a CMake option to exclude tests from the "make all" build. Use "cmake <absolute-path-to-source>
-DACSDK_EXCLUDE_TEST_FROM_ALL=ON" to enable it. When this option is enabled "make unit" and "make integration" still could be used to build and run the tests
* **Bug fixes**:
* Previously scheduled alerts now play following a restart
* General stability fixes
* Bug fix for CertifiedSender blocking forever if the network goes down while it's trying to send a message to AVS
* Fixes for known issue of Alerts integration tests fail: AlertsTest.UserLongUnrelatedBargeInOnActiveTimer and AlertsTest.handleOneTimerWithVocalStop
* Attempting to end a tap-to-talk interaction with the tap-to-talk button wouldn't work
* SharedDataStream could encounter a race condition due to a combination of a blocking Reader and a Writer closing before writing any data
* Bug-fix for the ordering of notifications within alerts scheduling. This fixes the issue where a local-stop on an alert would also stop a subsequent alert if it were to begin without delay
* **Known Issues**
* Capability agent for Notifications is not included in this release
* Inconsistent playback behavior when resuming content ("Alexa, pause." / "Alexa, resume."). Specifically, handling playback offsets, which causes the content to play from the start. This behavior is also occasionally seen with "Next" /
"Previous".
* `ACL`'s asynchronous receipt of audio attachments may manage resources poorly in scenarios where attachments are received but not consumed.
- Changes in this update:
- Better GStreamer error reporting. MediaPlayer used to only report `MEDIA_ERROR_UNKNOWN`, now reports more specific errors as defined in `ErrorType.h`.
- Codebase has been formatted for easier reading.
- `DirectiveRouter::removeDirectiveHandler()` signature changed and now returns a bool indicating if given handler should be successfully removed or not.
- Cleanup of raw and shared pointers in the creation of `Transport` objects.
- `HTTP2Stream`s now have IDs assigned as they are acquired as opposed to created, making associated logs easier to interpret.
- `AlertsCapabilityAgent` has been refactored.
- Alert management has been factored out into an `AlertScheduler` class.
- Creation of Reminder (implements Alert) class.
- Added new capability agent for `PlaybackController` with unit tests.
- Added Settings interface with unit tests.
- Return type of `getOffsetInMilliseconds()` changed from `int64_t` to `std::chronology::milliseconds`.
- Added `AudioPlayer` unit tests.
- Added teardown for all Integration tests except Alerts.
- Implemented PlaylistParser.
- Bug fixes:
- AIP getting stuck in `LISTENING` or `THINKING` and refusing user input on network outage.
- SampleApp crashing if running for 5 minutes after network disconnect.
- Issue where on repeated user barge-ins, `AudioPlayer` would not pause. Specifically, the third attempt to “Play iHeartRadio” would not result in currently-playing music pausing.
- Utterances being ignored after particularly long TTS.
- GStreamer errors cropping up on SampleApp exit as a result of accessing the pipeline before it’s been setup.
- Crashing when playing one URL after another.
- Buffer overrun in Alerts Renderer.
- [SampleApp crashing when issuing "Alexa skip" command with iHeartRadio.](https://github.com/alexa/avs-device-sdk/issues/153)
- [`HTTP2Transport` network thread triggering a join on itself.](https://github.com/alexa/avs-device-sdk/issues/127)
- [`HTTP2Stream` request handling truncating exception messages.](https://github.com/alexa/avs-device-sdk/issues/67)
- [`AudioPlayer` was attempting an incorrect state transition from `STOPPED` to `PLAYING` through a `playbackResumed`.](https://github.com/alexa/avs-device-sdk/issues/138)

- Fix race condition with reading attachments before a writer exists.
- Use of new Logging abstraction layer in modules - ADSL,AFML,ContextManager,AuthDelegate,AIP,KWD,Mediaplayer.

Changes in this update:
- Added the CapabilityAgent base class that is used to build capability agent
implementations.
- Added the ContextManager class that allows multiple Capability Agents to
store and access state. These events include context, which is used to
communicate the state of each capability agent to AVS:
- Recognize
- PlayCommandIssued
- PauseCommandIssued
- NextCommandIssued
- PreviousCommandIssued
- SynchronizeState
- ExceptionEncountered
- Implemented the SharedDataStream (SDS) to asynchronously communicate data
between a local reader and writer.

capability agent.
- Added the WakeWord Detector (WWD), which recognizes keywords in audio streams.
v0.3 implements a wrapper for KITT.ai.
- Added a new implementation of AttachmentManager and associated classes for use
with SDS.
- Updated the ACL to support asynchronously sending audio to AVS.
