Changes in this update:
**Enhancements**
* Support was added for the `fr_CA` locale.
* The Executor has been optimized to run a single thread when there are active job in the queue, and to remain idle when there are not active jobs.
* An additional parameter of `alertType` has been added to the Alerts capability agent. This will allow observers of alerts to know the type of alert being delivered.
* Support for programmatic unload and load of PulseAudio Bluetooth modules was added. To enable this feature, there is a [new CMake option](https://github.com/alexa/avs-device-sdk/wiki/CMake-parameters#bluetooth): `BLUETOOTH_BLUEZ_PULSEAUDIO_OVERRIDE_ENDPOINTS`. Note that [libpulse-dev is a required dependency](https://github.com/alexa/avs-device-sdk/wiki/Dependencies#bluetooth) of this feature.
* An observer interface was added for when an active Bluetooth device connects and disconnects.
* The `BluetoothDeviceManagerInterface` instantiation was moved from `DefaultClient` to `SampleApp` to allow applications to override it.
* The `MediaPlayerInterface` now supports repeating playback of URL sources.
* The Kitt.AI wake word engine (WWE) is now compatible with GCC5+.
* Stop of ongoing alerts, management of MessageObservers, and management of CallStateObservers have been exposed through DefaultClient.
**Bug Fixes**
* [Issue 953](https://github.com/alexa/avs-device-sdk/issues/953) - The `MediaPlayerInterface` requirement that callbacks not be made upon a callers thread has been removed.
* [Issue 1136](https://github.com/alexa/avs-device-sdk/issues/1136) - Added a missing default virtual destructor.
* [Issue 1140](https://github.com/alexa/avs-device-sdk/issues/1140) - Fixed an issue where DND states were not synchronized to the AVS cloud after device reset.
* [Issue 1143](https://github.com/alexa/avs-device-sdk/issues/1143) - Fixed an issue in which the SpeechSynthesizer couldn't enter a sleeping state.
* [Issue 1183](https://github.com/alexa/avs-device-sdk/issues/1183) - Fixed an issue where alarm is not sounding for certain timezones
* Changing an alert's volume from the Alexa app now works when an alert is playing.
* Added missing shutdown handling for ContentDecrypter to prevent the `Stop` command from triggering a crash when SAMPLE-AES encrypted content was streaming.
* Fixed a bug where if the Notifications database is empty, due to a crash or corruption, the SDK initialization process enters an infinite loop when it retries to get context from the Notifications capability agent.
* Fixed a race condition that caused `AlertsRenderer` observers to miss notification that an alert has been completed.
**Known Issues**
* `PlaylistParser` and `IterativePlaylistParser` generate two HTTP requests (one to fetch the content type, and one to fetch the audio data) for each audio stream played.
* Music playback history isn't being displayed in the Alexa app for certain account and device types.
* On GCC 8+, issues related to `-Wclass-memaccess` will trigger warnings. However, this won't cause the build to fail and these warnings can be ignored.
* Android error ("libDefaultClient.so" not found) can be resolved by upgrading to ADB version 1.0.40
* When network connection is lost, lost connection status is not returned via local TTS.
* `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 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.
* `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 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 text-to-speech (TTS).
* When the sample app is restarted and network connection is lost, Reminder TTS does not play. Instead, the default alarm tone will play twice.
Changes in this update:
**Enhancements**

* The SDK now supports [Opus](https://opus-codec.org/license/) encoding, which is optional. To enable Opus, you must [set the CMake flag to `-DOPUS=ON`](https://github.com/alexa/avs-device-sdk/wiki/Build-Options#Opus-encoding), and include the [libopus library](https://github.com/alexa/avs-device-sdk/wiki/Dependencies#core-dependencies) dependency in your build.
* The MediaPlayer reference implementation has been expanded to support the SAMPLE-AES and AES-128 encryption methods for HLS streaming.
* AES-128 encryption is dependent on libcrypto, which is part of the required openSSL library, and is enabled by default.
* To enable [SAMPLE-AES](https://github.com/alexa/avs-device-sdk/wiki/Dependencies#core-dependencies/Enable-SAMPLE-AES-decryption) encryption, you must set the `-DSAMPLE_AES=ON` in your CMake command, and include the [FFMPEG](https://github.com/alexa/avs-device-sdk/wiki/Dependencies#core-dependencies/Enable-SAMPLE-AES-decryption) library dependency in your build.
* A new configuration for [deviceSettings](https://github.com/alexa/avs-device-sdk/blob/v1.11.0/Integration/AlexaClientSDKConfig.json#L59) has been added.This configuration allows you to specify the location of the device settings database.
* Added locale support for es-MX.
**Bug Fixes**
* Fixed an issue where music wouldn't resume playback in the Android app.
* Now all equalizer capabilities are fully disabled when equalizer is turned off in configuration file. Previously, devices were unconditionally required to provide support for equalizer in order to run the SDK.
* [Issue 1106](https://github.com/alexa/avs-device-sdk/issues/1106) - Fixed an issue in which the `CBLAuthDelegate` wasn't using the correct timeout during request refresh.
* [Issue 1128](https://github.com/alexa/avs-device-sdk/issues/1128) - Fixed an issue in which the `AudioPlayer` instance persisted at shutdown, due to a shared dependency with the `ProgressTimer`.
* Fixed in issue that occurred when a connection to streaming content was interrupted, the SDK did not attempt to resume the connection, and appeared to assume that the content had been fully downloaded. This triggered the next track to be played, assuming it was a playlist.
* [Issue 1040](https://github.com/alexa/avs-device-sdk/issues/1040) - Fixed an issue where alarms would continue to play after user barge-in.
**Known Issues**
* `PlaylistParser` and `IterativePlaylistParser` generate two HTTP requests (one to fetch the content type, and one to fetch the audio data) for each audio stream played.
* Music playback history isn't being displayed in the Alexa app for certain account and device types.
* On GCC 8+, issues related to `-Wclass-memaccess` will trigger warnings. However, this won't cause the build to fail, and these warnings can be ignored.
* In order to use Bluetooth source and sink PulseAudio, you must manually load and unload PulseAudio modules after the SDK starts.
* 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.

* Added reference implementation of the EqualizerController for GStreamer-based (MacOS, Linux, and Raspberry Pi) and OpenSL ES-based (Android) MediaPlayers. Note: In order to use with Android, it must support OpenSL ES.
* New optional configuration for the [TemplateRuntime display card value](https://github.com/alexa/avs-device-sdk/blob/v1.10.0/Integration/AlexaClientSDKConfig.json#L144).
* A configuration file generator script, `genConfig.sh` is now included with the SDK in the **tools/Install** directory. `genConfig.sh` and it's associated arguments populate `AlexaClientSDKConfig.json` with the data required to authorize with LWA.
* Added Bluetooth A2DP source and AVRCP target support for Linux.
* Added Amazon for Business (A4B) support, which includes support for handling the new [RevokeAuthorization](https://developer.amazon.com/docs/alexa-voice-service/system.html#revokeauth) directive in the Settings interface. A new CMake option has been added to enable A4B within the SDK, `-DA4B`.
* Added locale support for IT and ES.
* The Alexa Communication Library (ACL), `CBLAUthDelegate`, and sample app have been enhanced to detect de-authorization using the new `z` command.
* Added `ExternalMediaPlayerObserver`, which receives notification of player state, track, and username changes.
* `HTTP2ConnectionInterface` was factored out of `HTTP2Transport` to enable unit testing of `HTTP2Transport` and re-use of `HTTP2Connection` logic.
**Bug Fixes**
* Fixed a bug in which `ExternalMediaPlayer` adapter playback wasn't being recognized by AVS.

Changes in this update:
**Enhancements**
* `AuthDelegate` and `AuthServer.py` have been replaced by `CBLAUthDelegate`, which provides a more straightforward path to authorization.
* Added a new configuration property called [`cblAuthDelegate`](https://github.com/alexa/avs-device-sdk/blob/master/Integration/AlexaClientSDKConfig.json#L2). This object specifies parameters for `CBLAuthDelegate`.
* Added a new configuration property called [`miscDatabase`](https://github.com/alexa/avs-device-sdk/blob/master/Integration/AlexaClientSDKConfig.json#L34), which is a generic key/value database to be used by various components.
* Added a new configuration property called [`dcfDelegate`](https://github.com/alexa/avs-device-sdk/blob/master/Integration/AlexaClientSDKConfig.json#L17) This object specifies parameters for `DCFDelegate`. Within this object, values were added for the 'endpoint' and `overridenDcfPublishMessageBody`. 'endpoint' is the endpoint to connect to in order to send device capabilities. `overridenDcfPublishMessageBody`is the message that will get sent out to the Capabilities API. Note: values within the `dcfDelegate` object will only work in `DEBUG` builds.
* Added a new configuration property called [`deviceInfo`](https://github.com/alexa/avs-device-sdk/blob/master/Integration/AlexaClientSDKConfig.json#L9) which specifies device-identifying information for use by the Device Capability Framework (DCF), and for authorization (CBLAuthDelegate).
* Updated the Directive Sequencer to support wildcard directive handlers. This allows a handler for a given AVS interface to register at the namespace level, rather than specifying the names of all directives within that namespace.
* Updated the Raspberry Pi installation script to include `alsasink` in the configuration file.
* Added `audioSink` as a configuration option. This allows users to override the audio sink element used in `Gstreamer`.
* Added an interface for monitoring internet connection status: `InternetConnectionMonitorInterface.h`.
* The Alexa Communications Library (ACL) is no longer required to wait until authorization has succeeded before attempting to connect to AVS. Instead, `HTTP2Transport` handles waiting for authorization to complete.
* Added the Device Capabilities Framework (DCF) delegate. Device capabilities can now be sent for each capability interface using DCF publish messages.
* The sample app has been updated to send DCF publish messages, which will automatically occur when the sample app starts. Note: a DCF publish message must be successfully sent in order for communication with AVS to occur.
* The SDK now supports HTTP PUT messages.
* Added support for opt-arg style arguments and multiple configuration files. Now, the sample app can be invoked by either of these commands: `SampleApp <configfile> <debuglevel>` OR `SampleApp -C file1 -C file2 ... -L loglevel`.
**Bug Fixes**
* Issues [447](https://github.com/alexa/avs-device-sdk/issues/447) and [553](https://github.com/alexa/avs-device-sdk/issues/553) Fixed the `AttachmentRenderSource`'s handling of `BLOCKING` `AttachmentReaders`.
* Updated the `Logger` implementation to be more resilient to `nullptr` string inputs.
* Fixed a `TimeUtils` utility-related compile issue.
* Fixed a bug in which alerts failed to activate if the system was restarted without network connection.
* Fixed Android 64-bit build failure issue.
**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.
* Some ERROR messages may be printed during start-up event if initialization proceeds normally and successfully.
* If an unrecoverable authorization error or an unrecoverable DCF error is encountered, the sample app may crash on shutdown.
* If a non-CBL `clientId` is included in the `deviceInfo` section of `AlexaClientSDKConfig.json`, the error will be reported as an unrecoverable authorization error, rather than a more specific error.
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.

* 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`

* 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.

* Music playback doesn't immediately stop when a user barges-in on iHeartRadio.
**Enhancements**
* ContextManager now passes the namespace/name of the desired state to StateProv
iderInterface::provideState(). This is helpful when a single StateProvider obje
ct provides multiple states, and needs to know which one ContextManager is askin
g for.
* The mime parser was hardened against duplicate boundaries.
* Added functionality to add and remove AudioPlayer observers to the DefaultClie
nt.
* Unit tests for Alerts were added.
* Added en-IN, en-CA and ja-JP to the SampleApp locale selection menu.

This allows a reader to move to an index which has not yet arrived in the SDS a
nd poll/block until it arrives.
* Added support for blocking Writers in the SharedDataStream class.
* Changed the default status code sent by MessageRequestObserverInterface::onSen
dCompleted() to SERVER_OTHER_ERROR, and mapped HTTP code 500 to SERVER_INTERNAL_
ERROR_V2.
* Added support for parsing stream duration out of playlists.
* Added a configuration option ("sampleApp":"displayCardsSupported") that allows
the displaying of display cards to be enabled or disabled.
* Named Timers and Reminders have been updated to fall back to the on-device bac
kground audio sound when cloud urls cannot be accessed or rendered.
**Bug Fixes**
* Removed floating point dependencies from core SDK libraries.
* Fixed bug in SpeechSynthesizer where it's erroneously calling stop more than once.
* Fixed an issue in ContentFetcher where it could hang during destruction until an active GET request completed.
* Fixed a couple of parsing bugs in LibCurlHttpContentFetcher related to case-sensitivity and mime-type handling.
* Fixed a bug where MediaPlayerObserverInterface::onPlaybackResumed() wasn't being called after resuming from a pause with a pending play/resume.
* Fixed a bug in LibCurlContentFetcher where it could error out if data is written to the SDS faster than it is consumed.

* Fixed some occurrences of SDK entering the IDLE state during the transition between Listening and Speaking states.
* Fixed a bug where PlaybackFinished events were not reporting the correct offset.
* An API change has been made to MediaPlayerInterface::getOffset(). This method is now required to return the final offset when called after playback has stopped.
* Fixed a problem where AIP was erroneously resetting its state upon getting a cancelDirective() callback.
**Known Issues**
* Capability agent for Notifications is not included in this release.
* `ACL`'s asynchronous receipt of audio attachments may manage resources poorly in scenarios where attachments are received but not consumed.
* GUI cards don't show for Kindle.
* The new SpeechSynthesizerState state values GAINING_FOCUS and LOSING_FOCUS were added as part of a work-around. The will likely be removed in subsequent releases.
* With the gstreamer-based MediaPlayer, after muting and unmuting, the next item starts playing rather than continuing with the current item.

- 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)
Changes in this update
- Added a sample app that leverages the SDK.
- Added an implementation of the `Alerts` capability agent.
- Added the `DefaultClient` class.
- Added the following classes to support directives and events in the
`StateSynchronizer`, `EndpointHandler`, and `ExceptionEncounteredSender`.
- Added unit tests for `ACL`.
- Updated `MediaPlayer` to play local files given an `std::istream`.
- Changed build configuration from `Debug` to `Release`.
- Removed `DeprecatedLogger` class.
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.
- Added AudioInputProcessor (AIP), an implementation of a SpeechRecognizer
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.
