Changes in this update:
**Enhancements**
* Added support for adjustment of alert volume.
* Added support for deletion of multiple alerts.
* The following `SpeakerInterface::Type` enumeration values have changed:
* `AVS_SYNCED` is now `AVS_SPEAKER_VOLUME`.
* `LOCAL` is now `AVS_ALERTS_VOLUME`.
**Known Issues**
* The `ACL` may encounter issues if audio attachments are received but not consumed.
* `SpeechSynthesizerState` currently uses `GAINING_FOCUS` and `LOSING_FOCUS` as a workaround for handling intermediate state. These states may be removed in a future release.
* The Alexa app doesn't always indicate when a device is successfully connected via Bluetooth.
* Connecting a product to streaming media via Bluetooth will sometimes stop media playback within the source application. Resuming playback through the source application or toggling next/previous will correct playback.
* When a source device is streaming silence via Bluetooth, the Alexa companion app indicates that audio content is streaming.
* The Bluetooth agent assumes that the Bluetooth adapter is always connected to a power source. Disconnecting from a power source during operation is not yet supported.
* On some products, interrupted Bluetooth playback may not resume if other content is locally streamed.
* On Raspberry Pi, when streaming audio via Bluetooth, sometimes the
audio stream stutters.
Changes in this update:
**Enhancements**
* `rapidJson` is now included with "make install".
* Updated the `TemplateRuntimeObserverInterface` to support clearing of `displayCards`.
* Added Windows SDK support, along with an installation script (MinGW-w64).
* Updated `ContextManager` to ignore context reported by a state provider.
* The `SharedDataStream` object is now associated by playlist, rather than by URL.
* Added the `RegistrationManager` component. Now, when a user logs out all persistent user-specific data is cleared from the SDK. The log out functionality can be exercised in the sample app with the new command: `k`.
**Bug Fixes**
* [Issue 400](https://github.com/alexa/avs-device-sdk/issues/400) Fixed a bug where the alert reminder did not iterate as intended after loss of network connection.
* [Issue 477](https://github.com/alexa/avs-device-sdk/issues/477) Fixed a bug in which Alexa's weather response was being truncated.
* Fixed an issue in which there were reports of instability related to the Sensory engine. To correct this, the `portAudio` [`suggestedLatency`](https://github.com/alexa/avs-device-sdk/blob/master/Integration/AlexaClientSDKConfig.json#L62) value can now be configured.
**Known Issues**
* The `ACL` may encounter issues if audio attachments are received but not consumed.
* `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.
* The Windows sample app sometimes hangs on exit.
* GDP receives a `SIGPIPE` when troubleshooting the Windows sample app.
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**
* Added the Notifications Capability Agent. This allows a client to receive notification indicators from Alexa.
* Added support for the `SoftwareInfo` event. This code is triggered in the `SampleApp` by providing a positive decimal integer as the "firmwareVersion" value in "sampleApp" object of the `AlexaClientSDKConfig.json`. The reported firmware version can be updated after starting the `SampleApp` by calling `SoftwareInfoSender::setFirmwareVersion()`. This code path can be exercised in the `SampleApp` with the new command: `f`.
* Added unit tests for Alerts.
* The GStreamer-based pipeline allows for the configuration of `MediaPlayer` output based on information provided in `Config`.
* Playlist streaming now uses a `BLOCKING` writer, which improves streaming efficiency.
**Bug Fixes**
* Fixed bug where `SpeechSynthesizer` would not stop playback when a state change timeout was encountered.
* Fixed the `SampleApplication` destructor to avoid segfaults if the object is not constructed correctly.
* Fixed bug where `AudioPlayer` would erroneously call `executeStop()` in `cancelDirective()`.
* [Issue 396](https://github.com/alexa/avs-device-sdk/issues/396) - Fixed bug for compilation error with GCC7 in `AVSCommon/SDKInterfaces/include/AVSCommon/SDKInterfaces/Audio/AlertsAudioFactoryInterface.h`
* [Issue 384](https://github.com/alexa/avs-device-sdk/issues/384) - Fixed bug that caused `AuthServer.py` to crash.
* Fixed bug where a long delay was encountered after pausing and resuming a large Audible chapter.
* Fixed bug that caused named timers and reminders to loop for an additional `loopCount` .
* Fixed memory corruption bug in `MessageInterpreter`.
* Fixed illegal memory accesses in `MediaPlayer` logging.
**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.
