Changes in this update:
**Bug Fixes**
* Fixed a bug where the same URL was being requested twice when streaming iHeartRadio. Now, a single request is sent.
* Corrected pause/resume handling in `ProgressTimer` so that extra `ProgressReportDelayElapsed` events are not sent to AVS.
**Known Issues**
* 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 the network connection is lost, the Reminder TTS message does not play. Instead, the default alarm tone will play twice.
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 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.

Changes in this update:
**Enhancements**
* Added support for the new Alexa [DoNotDisturb](https://developer.amazon.com/docs/alexa-voice-service/donotdisturb.html) interface, which enables users to toggle the do not disturb (DND) function on their Alexa built-in products.
* 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.

* 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**

* 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.
* [Issue 973](https://github.com/alexa/avs-device-sdk/issues/973) - Fixed issues related to `AudioPlayer` where progress reports were being sent out of order or with incorrect offsets.
