[liuv...@google.com]

Hi all,

Cloud SDK 177.0.0 is now available for download at:
https://developers.google.com/cloud/sdk/.

New in this version:

### Breaking Changes

* **(BETA - DEPRECATED)** The `--include-ignored-file` flag of `gcloud
beta
functions deploy` is now deprecated. Added support for using a
`.gcloudignore` file instead.
* The `gcloud pubsub <snapshots|subscriptions|topics> <create|update>` and
`gcloud pubsub subscriptions update` commands have been updated:
* These now throw an exception when any of the API requests fail.
The
exception contains the list of failed requests.
* These now only output the resources corresponding to successful
requests.
* The `success` and `reason` fields have been removed from the
output of
these commands.

### Google Cloud Endpoints

* `gcloud endpoints` and `gcloud services` are now generally available.

### Google App Engine

* `gcloud app deploy` now uses a new runtime build pipeline to deploy
apps for
Python. This enables more robust and flexible deployments in some
cases. To
revert to the legacy builder, run `gcloud config set
app/use_runtime_builders false` from the command line.
* Go 1.8 is now generally available and the default Go runtime.
* Google App Engine components have been updated to 1.9.62.
Please visit the following release notes for details:
* Python -

### Google Compute Engine

* (ALPHA) Added support to update the default network tier on a Compute
Engine
project: `gcloud alpha compute project-info update
--default-network-tier
DEFAULT_NETWORK_TIER`.

### Google Cloud SQL

* (BETA) Added `gcloud beta sql export csv` to support exporting data
from a
Cloud SQL instance to a CSV file.
* (BETA) Added `gcloud beta sql export sql` with the eventual goal of
replacing `gcloud sql instances export`.

### Google Cloud Storage

* Updated gsutil component to 4.28
