gRPC releases Beta opening door for use in production environments

Posted by Mugur Marculescu, Product Manager

The gRPC team is excited to announce the immediate availability of gRPC Beta. This release marks an important point in API stability and going forward most API changes are expected to be additive in nature. This milestone opens the door for gRPC use in production environments.

We’re also taking a big step forward in improving the installation process. Over the past few weeks, we’ve rolled out gRPC packages to Debian Stable/Backports. Installation in most cases is now a two line install using the Debian package and available language specific package managers (e.g. maven, pip, gem, composer, pecl, npm, nuget, pod). In addition gRPC docker images are now available on Docker Hub.

We’ve updated the documentation on grpc.io to reflect the latest changes and released additional language-specific reference docs. See what’s changed with the Beta release in the release notes on Github for Java, Go and all other languages.

In the coming months, the focus of the gRPC project will be to keep improving performance and stability and adding carefully chosen features for production use cases. This is part of our principles and goals to enable highly performant and scalable APIs and microservices on top of HTTP/2. Documentation will also be clarified and will continue to improve with new examples and guides.

We’ve been very excited to see the community response to gRPC and the various projects starting to use it (etcd v3 experimental api, grpc-gateway for RESTful APIs and others). We really want to thank everyone who contributed code, gave presentations, adopted the technology and engaged in the community. With your help support we look forward to the 1.0!

Present to anyone from wherever you are

Posted by Fenil Shah, Software Engineer, Google Slides

Google Slides helps you share your big ideas with the world, but sometimes presenting these ideas can be challenging. In June, Slides added support for Chromecast and Airplay, which made it easier to project your slides on the big screen. Now there’s another new way to share your work: easy presenting to Hangouts video calls. Teammates, partners, clients and classmates can see your ideas, even if they’re on the other side of the planet.


As you get ready for the big meeting, all you need is your Android phone or tablet. With one tap of the present button, you’ll see the option to present to a Hangouts video call. Meetings that are scheduled on your calendar will automatically be listed, so you can be up and running in no time.

You’ll also get a handy look at whos on the call before you start presenting. Once you’re ready to rock, you can use your mobile device to advance slides, view speaker notes and stay on track with a built-in timer.

Presenting just got even easier with Google Slides on Android – available starting today and rolling out over the next few days.
