Version 1.7.1 alexa-client-sdk Changes in this update: Enhancements * Added the Bluetooth interface, which manages the Bluetooth connection between Alexa-enabled products and peer devices. This release supports A2DP-SINK and AVRCP profiles. Note: Bluetooth is optional and is currently limited to Raspberry Pi and Linux platforms. * Added new Bluetooth dependencies for Linux and Raspberry Pi. * Device Capability Framework (DCF) renamed to Capabilities. * Updated the non-CBL client ID error message to be more specific. * Updated the sample app to enter a limited interaction mode after an unrecoverable error. Bug Fixes * Issue 597 - Fixed a bug where the sample app did not respond to locale change settings. * Fixed issue where GStreamer 1.14 MediaPlayerTest failed on Windows. * Fixed an issue where a segmentation fault was triggered after unrecoverable error handling. 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 streaming silence via Bluetooth, the Alexa companion app will sometimes indicate that media 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. * When streaming content via Bluetooth, under certain conditions playback will fail to resume and the sample app hangs on exit. This is due to a conflict between the GStreamer pipeline and the Bluetooth agent. * 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.

Version 1.5.0 alexa-client-sdk 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.

Version 1.9.0 alexa-client-sdk Changes in this update: Enhancements Added Android SDK support, which includes new implementations of the MediaPlayer, audio recorder, and logger. Added the InteractionModel interface, which enables Alexa Routines. Optional configuration changes have been introduced. Now a network interface can be specified to connect to the SDK via curl. Build options can be configured to support Android. Added GUI 1.1 support. The PlaybackController has been extended to support new control functionality, and the System interface has been updated to support SoftwareInfo. Bug Fixes Installation script execution time has been reduced. Now a single branch clone is used, such as the master branch. Issue 846 - Fixed a bug where audio stuttered on slow network connections. Removed the SpeakerManager constructor check for non-zero speakers. Issue 891 - Resolved incorrect offset in the PlaybackFinished event. Issue 727 - Fixed an issue where the sample app behaved erratically upon network disconnection/reconnection. Issue 910 - Fixed a GCC 8+ compilation issue. Note: issues related to -Wclass-memaccess will still trigger warnings, but won't fail compilation. Issue 871 Issue 880 - Fixed compiler warnings. Fixed a bug where Ted Talks would not stream via TuneIn. Fixed an issue where the PryonLiteKeywordDetector would not restart. Fixed an issue where PlaybackStutterStarted and PlaybackStutterFinished events were not being sent due to a missing Gstreamer queue element. Fixed a bug where the CapabilitiesDelegate database was not being cleared upon logout. Fixed in issue that caused the following compiler warning “class has virtual functions but non-virtual destructor”. Fixed a bug where BlueZDeviceManager was not properly destroyed. Fixed a bug that occurred when the initializer list was converted to std::unordered_set. Fixed a build error that occurred when building with BUILD_TESTING=Off. 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. * These CapabilitiesDelegateTest tests have been temporarily disabled to prevent build errors for the Android build: CapabilitiesDelegateTest.withCapabilitiesHappyCase, CapabilitiesDelegateTest.republish, CapabilitiesDelegateTest.testClearData. * make integration is currently not available for Android. In order to run integration tests on Android, you'll need to manually upload the test binary file along with the any input file. At that point, the adb can be used to run the integration tests. * On Raspberry Pi running Android Things with HDMI output audio, beginning of speech is truncated when Alexa responds to user TTS. * Spotify does not completely shut down when the sample app quits.

Version 1.8 alexa-client-sdk 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.

Version 1.4.0 alexa-client-sdk 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.

Version 1.1.0 alexa-client-sdk - 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)

Version 1.2.0 alexa-client-sdk 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.
