v1.3.0

Common

• Response headers are now stored in olp::client::HttpResponse. olp::client::OlpClient::CallApi() collects and adds headers to the response.
• X-Correlation-ID is now extracted from the HTTP response headers and used for subsequent requests in olp::dataservice::read::StreamLayerClient.
• Added a new backdown strategy to olp::client::RetrySettings.
  The default implementation is olp::client::ExponentialBackdownStrategy that restricts the maximum wait time during failed retries of network requests in the olp::network::client::OlpClient class (both synchronous and asynchronous versions). The accumulated wait time during retries should not be longer than the RetrySettings.timeout property.
• Added curl_global_init() and curl_global_cleanup() to the olp::http::NetworkCurl class (Linux default implementation).
  For more information, see the olp::client::OlpClientSettingsFactory::CreateDefaultNetworkRequestHandler() function.
• Fixed MSVC, Clang, and GCC warnings. Now, when you build with -Wall -Wextra, you should not face any hidden warnings, as the codebase is protected by a pre-release verification job.
• Fixed the possible thread concurrency problem in the olp::client::OlpClient class that resulted in a crash in some situations.
• Reduced data copy in the JSON serializers to increase performance.

olp-cpp-sdk-authentication

• Added a new API to olp::authentication::AuthenticationClient that you can use to perform a generic federated authentication with a custom request body.
• Added the olp::authentication::AuthenticationClient::IntrospectApp() method that you can use to retrieve information
  about the application associated with a particular access token.
• Added a new olp::authentication::AuthenticationClient constructor using olp::authentication::AuthenticationSettings to setup network and task scheduler. It is a part of an ongoing authentication refactoring. Switch to this constructor instead of using the individual setters.

olp-cpp-sdk-dataservice-read

• olp::dataservice::read::PartitionsRequest now supports a list of partition IDs. This way, when you use olp::dataservice::read::VersionedLayerClient and olp::dataservice::read::VolatileLayerClient, you can also request certain partitions instead of the entire layer metadata.
• Added the Seek method to olp::dataservice::read::StreamLayerClient. This method can be used to start reading messages from a stream layer at any given position.
• Added the Poll method to olp::dataservice::read::StreamLayerClient. This method reads messages from a stream layer and commits successfully consumed messages before handing them over to you.
• Added the olp::dataservice::read::TileRequest class and corresponding GetData overload to olp::dataservice::read::VersionedLayerClient. Now, you can get data using a tile key. Internally, the metadata retrieval is optimized by using a quadtree request and saves bandwidth on subsequent GetData calls.
• Added additional fields to the olp::dataservice::read::PartitionsRequest class. Now, you can access the following additional metadata
  fields: data size, compressed data size, checksum, and CRC.
• Deprecated the WithVersion and the GetVersion methods in the olp::dataservice::read::DataRequest, olp::dataservice::read::PartitionsRequest and olp::dataservice::read::PrefetchTilesRequest classes. olp::dataservice::read::VersionedLayerClient now locks the catalog version either to the value provided on the constructor or by requesting the latest catalog version from the backend. This ensures that consistent data is provided for the instance lifecycle.
• Fixed cache keys by appending 'partition' and 'partitions' to key values in olp::dataservice::read::VolatileLayerClient.
• Fixed the infinite loop in the olp::dataservice::read::VersionedLayerClient::PrefetchTiles() method when min/max levels are not specified.
