Bigtable v1.0.0

• bug: the library will return an error instead of simply discarding unknown IAM
  fields.
• feature: update googleapis protos to a more recent version.
• cleanup: marked rarely used CMake options as advanced. They will no longer
  show up by default in your CMake UI.
• Several internal cleanups, such as removing unused code in
  google::cloud::bigtable::internal, fixing constant names to follow the
  Google Style Guide, simplify the generation of version metadata, make it
  easier to import the code into Google, turned on -Wextra for our builds,
  moved the sanitizer builds to Bazel, and refactoring generic gRPC utilities
  to a new common library.

Google Cloud Storage v1.2.0

• Breaking Change: we accidentally left two functions in the public API,
  they are now removed. These functions were used to convert
  google::cloud::storage::ServiceAccount classes to and from JSON objects.
• Breaking Change: we removed the functions in
  google::cloud::storage::IdempotencyPolicy for
  internal::InsertObjectStreamingRequest. This class is no longer used and the
  functions are unnecessary. This breakage only affects applications that define
  a custom IdempotencyPolicy.
• bug: Fixed WriteObject() to actually retry the upload for each chunk, not
  just retry the creation of the upload session.
• feature: add examples showing how to mock a google::cloud::storage::Client.
• feature: allow applications to load service account credentials from the
  standard locations, but also change the scopes and subject as the credentials
  are loaded. Thanks to @timford for contributing this fix.
• bug: resuming an already finalized upload was not working correctly. Now the
  library restores the stream, but the stream is immediately closed (it is
  incorrect to write more data), and has the object metadata immediately
  available. Thanks to @Jseph for contributing this fix.
• bug: on Windows, storage::Client::UploadFile() and
  storage::Client::DownloadFile() were always treating the files as text,
  which meant their contents were transformed in unexpected ways. They are now
  always treated as binary.
• bug: we were still leaking a few macros from the nlohmann json library to the
  user's namespace. This is now fixed. Thanks to @remyabel for helping us with
  this.
• feature: reduce data copies during download.
• bug: return an error if the IAM bindings contain unknown fields, previously
  the library was discarding these fields.
• Several internal cleanups, such as fixing constant names to match the Google
  Style Guide, simplify the generation of version metadata, make the integration
  tests more reliable by using several service accounts for each run, use
  -Wextra in our builds, and a few more.

Bigtable v0.10.0

• Breaking Changes
  • The return type for WaitForConsistencyCheck() was a future<StatusOr<bool>>
    where most related functions return a bigtable::Consistency enum.
  • Table::CheckAndMutateRow returns StatusOr<bool> to indicate which
    branch of the predicate was taken in the atomic change. Meanwhile,
    AsyncCheckAndMutateRow() returned a future<StatusOr<proto-with-long-name>>.
    Changed the async and sync versions to return
    future<StatusOr<MutationBranch>>. MutationBranch is an enum as
    StatusOr<bool> is too eay to use incorrectly.
  • Removed the Collection template parameter from Table::SampleRows.
  • Fixed the last function, WaitForConsistencyCheck, that returned
    std::future to return google::cloud::future<>. The function name
    changed too, to be more consistent with similar functions.
  • Remove all the "strong types" for bigtable, such as InstanceId,
    ClusterId, TableId, etc. This changed some of the constructors for
    bigtable::Table and several member functions in bigtable::Table,
    bigtable::TableAdmin, and bigtable::InstanceAdmin.
• Changes:
  • Implemented TableAdmin::AsyncWaitForConsistency.
  • Implemented Table::AsyncReadRows.
  • DeleteAppProfile defaults to ignore_warnings=true.

GCS v1.1.0

• Implemented option to read an object starting from an offset.
• Automatically restart downloads on error. With this change the download is
  restarted from the last received byte, and using the object generation used
  in the original download as well. (#2693)
• Bugfixes:
  • Service account credentials not refreshing properly. (#2691)
  • Fix build for macOS+CMake. (#2698)
  • WriteObject now supports empty streams. (#2714)

GCS v1.0.0

• Declared GA and updated major number.
• Support signed policy documents.
• Support service account key files in PKCS#12 format (aka .p12).
• Support signing URLs and policy documents using the SignBlob API, this is
  useful when using the default service account in GCE to sign URLs and policy
  documents.

Bigtable v0.9.0

• Breaking Changes
  • Return google::cloud::future from InstanceAdmin functions: this is
    more consistent with all other functions returning futures.
  • Remove unused bigtable::GrpcError: the library no longer raises this
    exception, any code trying to catch the exception should be modified to
    handle errors via StatusOr<T>.
  • Remove Snapshot-related functions, tests, examples, etc.: this is
    whitelisted functionality in Cloud Bigtable and it is no longer expected
    to reach GA.
• Continue to implement more async APIs (Async*() methods) for the
  InstanceAdmin, TableAdmin, and Table classes
  (Note: These are not yet stable)
• Bugfixes:
  • Need ignore_warnings to actually delete an AppProfile.
  • Fix portability/logical errors in shell scripts.
  • Fix a race condition in MutationBatcher.
• Implemented a number of previously missing code samples.

Common v0.7.0

• Support move-only callables in future<T>
• Avoid std::make_exception_ptr() in future_shared_state_base::abandon().

Bigtable

• Breaking change: Table::BulkApply now returns a
  std::vector<FailedMutation> instead of throwing an exception.
• In the future we will remove all the google::cloud::bigtable::noex::*
  classes. We are moving the implementation to google::cloud::bigtable::*.
• Continuing to implement more async APIs (Note: These are not yet stable):
  • InstanceAdmin::AsyncDeleteInstance
  • Table::AsyncCheckAndMutateRow
  • TableAdmin::AsyncDeleteTable
  • TableAdmin::AsyncModifyColumnFamilies
• BulkMutator now returns more specific errors instead of generic UNKNOWN.
• Improved install instructions, which are now tested with our CI builds.
• CMake-config files now work without pkg-config.
• Removed the googleapis submodule. The build system now automatically
  downloads all deps.

Bigtable

• Moved repo organization from GoogleCloudPlatform -> googleapis.
• Implemented several more async functions.
• Breaking change: Started migrating functions to StatusOr and away from
  throwing exceptions.
• Several fixes to bulk mutator (#1880)
• Disabled make install for external projects.
• Row now has a move constructor.
• Increased default message length limit.
• Now testing build with libc++ on Linux.
• Fixed some bugs found by Coverity scans.

Storage

  StatusOr<T> return values.
• Lots of cleanup to documentation and example code.
• Avoids use of StatusOr::value() when the validity was already checked.
• Client::ListBuckets() now directly returns ListBucketsReader, because it
  cannot fail so StatusOr was not needed.

  instead.
• 502s are now retryable errors from GCS.
• Breaking change: LockBucketRetentionPolicy returns a BucketMetadata
  now instead of void.
• Cleaned up documentation and example code.

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".
