Hello all Golem users and fans! Despite the current adverse global situation, the Golem team has good news for you :)

With today’s launch, we have reached an important milestone. This current release - Clay Golem Beta 0.23.0 introduces the Task API to mainnet, thereby completing the long-awaited transition from Brass to Clay.

Task API on mainnet

With Task API on mainnet, developers can now deploy their own dockerized apps to the Golem Network without a need for them to be included in Golem releases. Effectively, it enables much more robust release cycles for specific Golem use cases.

Of course, you can still use gWASM to develop your apps but the Task API gives you a lot more freedom on the range of tools that you can use to build such an app.

With the Task API still in beta, we can’t yet guarantee its perfection and complete lack of bugs. However, based on the feedback we have gathered during our own in-house testing and from those of you who started playing with the Task API on their own, we were able to introduce several important fixes and are confident enough to announce it is mainnet-ready.

There are two ways for you to use your Task API apps as a requestor. After you publish your app, you’ll either need to reach out to the providers who’ll be requested to whitelist your repository - or - you can now reach out to us to put your repository on a public whitelist that all Golem nodes use.

There’s one app available for the Task API out of the box -- the Blender renderer app which you can have a look at and use to test the Task API on Golem network without getting too technical. Plus, there is a tutorial app that you can reference when building your own Task API app for Golem.

To have a look at how this is done with Clay Golem 0.23, please refer to:

Other updates

Majority of the other changes in this release pertain to the underlying Golem code and are not directly visible to the user. The most important of them is the introduction of the new broadcast protocol, which enables us to publish broadcasts to Golem Network - mostly to announce new releases but possibly to signal other important updates to all of our users’ nodes.

Apart from that, we have improved our gWASM platform to make running WASM apps on Golem smoother.

And lastly, as usual, we’re including a lot of other fixes that should either address some of the issues you have reported to us or generally improve your experience with Golem in other ways.

For those of you interested in even more details, please consult the full changelog.

As always, we wholeheartedly encourage you to download the update and share any and all feedback - pertaining to both Golem itself and to any of our newly-introduced pieces of functionality - with us on chat, reddit and over email.

Here’s what to do if you want to upgrade:

Upgrading to Clay Golem Beta 0.23.0

Windows

Download and execute the installer from our release server.

Please be aware that since version 0.19+, Golem uses Docker for Windows. Docker for Windows comes with a new type of virtualization support: Hyper-V (Windows Server Virtualization) in place of the old Docker Toolbox.

If you are using any other virtualization software (for eg. Docker Toolbox, VMware), do not install Hyper-V as this could potentially impact performance.

Also, if you are a Windows 10 Home user you will not be able to install Hyper-V as it's not supported on this version of Windows. Fortunately, we have kept Docker Toolbox support in this case. The only downside is that you will have to install Docker Toolbox manually (available here) because it's no longer part of our installation package. You’ll find more detailed Golem+Docker Toolbox installation instructions in our docs.

If you encounter any problems with Hyper-V you can still uninstall it, and try to run Golem with Docker Toolbox.

If any errors occur during any process, please let us know in the testers channel at chat.golem.network or write an email to contact@golem.network (make sure to include “Error” in the subject field so we can catch it quickly).

Ubuntu

Download the Linux installation script. In terminal, run:

chmod +x install.sh && ./install.sh

macOS

To upgrade Golem, type commands below to update Golem:

brew upgrade golem
brew cask upgrade golem
brew unlink golem
brew unlink hyperg
brew link golem
brew link hyperg

With those simple steps in place, you should be running the latest release of Golem for macOS.

Important! Before you run Golem make sure to be running Docker for Mac:

Cmd + space bar, type Docker and hit enter.

Confirm that Docker is running properly. If you encounter any issues with Docker for Mac please follow instructions on Docker for Mac github.
