Other Changes

• fix(oauth2): only enable via GOOGLE_CLOUD_CPP_ENABLE (#12911)

When compiling with CMake, the oauth2 used to be automatically enabled if GOOGLE_CLOUD_CPP_REST was manually enabled or enabled by a separate library. That made it impossible to shard a build with separate builds for oauth2, storage and compute.

v2.17.0

• fix(storage): check ReadObject options at runtime (#12841)
• feat(storage): MatchGlob for ListObjects() (#12840)
• doc(storage): describe default project search (#12833)

Common Libraries

• fix(oauth2): do not require id_token in creds (#12867)

Other Changes

We have stopped testing with GCC 7.5.0 on openSUSE/Leap: this distro uses
GCC 7.5.0 by default. This specific version of GCC crashes when compiling some
of the files generated by Protobuf 24.x. In other distros we test with GCC 7.3,
without problems. And we also test with newer versions of GCC without problems.
The exact files that cause the compiler to crash seem to change with minor
changes in Protobuf or the input .proto files, making it difficult to maintain
some kind of exclusion list.

We have stopped testing with GCC 7.5.0 on openSUSE/Leap, and recommend you use
GCC >= 8 to compile google-cloud-cpp. If you must compile with GCC 7.5.0,
consider only enabling the libraries you will need.

v2.16.0

New Libraries

We are happy to announce the following GA libraries. Unless specifically noted,
the APIs in these libraries are stable, and are ready for production use.

• Compute Engine
• Infrastructure Manager
• NetApp

Discovery Engine

New *Client for conversational search.

OAuth2

• feat(oauth2): add quickstart, README, etc. (#12754)

OpenTelemetry

We instrumented the Google Cloud C++ libraries for distributed tracing using
OpenTelemetry. All client libraries are instrumented in some capacity.

Features to enable the collection and export of these traces are now GA. See the
quickstart within the library to learn more about these tools.

Policy Troubleshooter

Remove PoliciesClient. This client was placed in the wrong library. The
correct location is google/cloud/iam/v2.

Storage

• fix(storage): trace auth when default credentials are assumed (#12672)
• docs(storage): more on InsertObject vs. WriteObject (#12577)

Common Libraries

• feat(common): new *Option to configure HTTP proxy (#12766)
• fix: export headers with top-level Bazel targets (#12762)
• fix: gRPC auth logging enabled by "auth" (#12702)
• fix: add implicit routing in GAPICs (#12544)

Known issues

Compiling gRPC with Bazel and Clang >= 16 requires --features=-layering_check
in your Bazel command-line. For more details, see grpc#34482.

v2.15.1

Policy Troubleshooter

Remove PoliciesClient. This client was placed in the wrong library. The
correct location is google/cloud/iam/v2.

Full Changelog: v2.15.0...v2.15.1

v2.15.0

New Libraries

We are happy to announce the following GA libraries. Unless specifically noted,
the APIs in these libraries are stable, and are ready for production use.

• Datastore
• Discovery Engine API
• Policy Simulator
• Policy Troubleshooter

Cloud IoT

The Cloud IoT Core service has been [shutdown][cloud-iot-shutdown]. We removed
the corresponding C++ client library as it is no longer usable.

BeyondCorp API

Parts of the BeyondCorp API are restricted to only existing customers and will
be decommissioned. No C++ customers are affected, so we are removing the
unusable components from the C++ libraries. More information in the BeyondCorp
announcement.

Natural Language AI

We expanded the library to include the v2 version of the API.

Notebooks

We expanded the library to include the v2 version of the API.

Other Changes

Bazel Testing: from v2.15.0 we will only test with Bazel >= 6.0.0. We do not
consider this a breaking change, as Bazel 5.x has been in maintenance mode for
more than 6 months.

CMake Proto Libraries: We only compile service-specific protos if the
corresponding client library is enabled, via -DGOOGLE_CLOUD_CPP_ENABLE=....

This change reduces build times for customers who use CMake but who are not
using all of the client libraries listed below.

We considered it a bug that customers building with CMake were forced
to compile large proto libraries that they did not need. It was certainly
confusing.

Any change in behavior, including fixing bugs, can be considered "breaking". By
policy we don't consider bug fixes to be breaking changes. We applied that
policy in this case.

The impacted libraries are:

• bigquery
• bigtable
• dialogflow_es
• iam
• logging
• pubsub
• speech
• storage
• texttospeech
• trace

If you are dependent on any of these proto libraries and you are not
compiling the corresponding client library, you will need to update your build
scripts.

For example, if you depend on google_cloud_cpp_speech_protos (e.g., if you
have been using this library to make calls to Cloud Speech using raw gRPC), add
-DGOOGLE_CLOUD_CPP_ENABLE=...,speech,... to your CMake configure command. If
you build with vcpkg, include speech in your install command.

Note that google_cloud_cpp_storage_protos are associated with the
experimental-storage-grpc feature, not the storage feature.
