Changes in this update:
Enhancements
Added local stop functionality. This allows a user to stop an active function, such as an alert or timer, by uttering "Alexa, stop" when an Alexa-enabled product is offline.
Alerts in the background now stream in 10 sec intervals, rather than continuously.
Added support for France to the sample app.
friendlyName can now be updated for BlueZ implementations of BlueZBluetoothDevice and BlueZHostController.
Bug Fixes
Fixed an issue where the Bluetooth agent didn't clear user data upon reset, including paired devices and the uuidMapping table.
Fixed MediaPlayer threading issues. Now each instance has it's own glib main loop thread, rather than utilizing the default main context worker thread.
Fixed segmentation fault issues that occurred when certain static initializers needed to be initialized in a certain order, but the order wasn't defined.
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.
On Raspberry Pi, BlueALSA must be terminated each time the device boots. See Raspberry Pi Quick Start Guide for more information.
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.
* Music playback doesn't immediately stop when a user barges-in on iHeartRadio.
