Bigtable

• Restore support for gcc-4.8.
• @remyabel cleaned up some hard-coded zone names in the examples.
• More experimental asynchronous APIs, including AsyncReadRows. Note that we
  expect to change all these experimental APIs as described in
  #1543.
• @remyabel contributed changes to disable the unit and integration tests. This
  can be useful for package maintainers.
• New Bigtable filter wrapper that accepts a single column.
• Breaking Change: remove the as_proto_move() member functions in favor
  of as_proto() &&. With the latter newer compilers will warn if the object
  is used after the destructive operation.

Storage

• Try to use the exception mask in the IOStream classes
  (storage::ObjectReadStream and storage::ObjectWriteStream). This allows
  applications to check errors locally via rdstate(). Note that applications
  that disable exceptions altogether must check the status() member function
  for these IOStream classes. It is impossible to set the rdstate() for all
  failures when exceptions are disabled.
• Support reading only a portion of a Blob.
• Support building with gcc-4.8.
• Many internal changes to better support applications that disable exceptions.
  A future release will include APIs that do not raise exceptions for error
  conditions.
• @remyabel contributed changes to disable the unit and integration tests. This
  can be useful for package maintainers.
• Implement a function to create signed URLs (Client::CreateV2SignedUrl).
• Support resumable uploads in any upload operation.

Common

• Support compiling with gcc-4.8.
• Fix GCP_LOG() macro so it works on platforms that define a DEBUG pre-processor symbol.
• Use different PRNG sequences for each backoff instance, previously all the clones of a backoff policy shared the same sequence.
• Workaround build problems with Xcode 7.3.

v0.4.0 Release.

Bigtable

• More experimental asynchronous APIs, note that we expect to change all these
  experimental APIs as described in #1543.
• Most of the admin operations now have asynchronous APIs.
• All asynchronous APIs in noex::* return an object through which applications
  can request cancellation of pending requests.
• Prototype asynchronous APIs returning a google::cloud::future<T>,
  applications can attach callbacks and/or block on a
  google::cloud::future<T>.

Storage

• Use resumable uploads for large files in Client::UploadFile().
• Implement support for the userIp optional query parameter.
• BREAKING CHANGE Client::RewriteObject(), Client::CopyObject(), and
  Client::ComposeObject no longer require the ObjectMetadata argument.
  Instead use WithObjectMetadata(), which can be omitted if you do not need
  to set any metadata attributes in the new object.
• When using OpenSSL-1.0.2 the client library needs to configure the
  locking callbacks
  for OpenSSL. However, the application may disable this behavior if the
  application developer is going to use their own locking callbacks.
• When refreshing OAuth2 access tokens the client library uses the same retry
  and backoff policies as used for the request itself.
• Applications can set object metadata attributes via the WithObjectMetadata
  optional argument to Client::InsertObjectMedia().
• Applications can configure the library to only retry idempotent operations.
• The client library can use Google Compute Engine credentials to access the
  service.

Common

• Implement google::cloud::future<T> and google::cloud::promise<T> based on ISO/IEC TS 19571:2016, the "C++ Extensions for Concurrency" technical specification, also known as "futures with continuations".

v0.3.0 Release.

This is the v0.3.0 release of the Google Cloud C++ Client Libraries.

Bigtable

• Experimental asynchronous APIs.
• Include an example that illustrates how to use OpenCensus and the Cloud
  Bigtable C++ client library.
• Several cleanups around dependency management with CMake.
• Jason Zaman contributed improvements and fixes to support soversion numbers
  with CMake.
• Lots of improvements to the code coverage in the examples and tests.
• Fixed multiple documentation issues, including a much better landing page
  in the Doxygen documentation.

Storage

• Automatically compute MD5 hashes and CRC32C checksums when objects are
  uploaded and downloaded. Any hash or checksum mismatched results in an
  exception. Applications can MD5 hashes, CRC32C checksums or both on any
  request.
• Parse Bucket lock and retention policy attributes in object and bucket
  metadata.
• Add APIs to upload and download files with a single function call.
• Improved the error messages generated when the credentials file is missing
  or has invalid contents.
• Jason Zaman contributed improvements and fixes to support soversion numbers
  with CMake.

Common

• google::cloud::optional<T> an intentionally incomplete implementation of
  std::optional<T> to support C++11 and C++14 users.
• Applications can configure google::cloud::LogSink to enable logging in some
  of the libraries and to redirect the logs to their preferred destination.
  The libraries do not enable any logging by default, not even to stderr.
• google::cloud::SetTerminateHandler() allows applications compiled without
  exceptions, but using the APIs that rely on exceptions to report errors, to
  configure how the application terminates when an unrecoverable error is
  detected by the libraries.

This is the v0.3.0 (pre-)release of the Google Cloud C++ Client Libraries.
