Dear farmers,

We are live on mainnet with TF Grid 3.17.

In addition to the updates stated above, we have also deployed a new release of QSFS that includes the Pulumi deployer.

This release includes expanded documentation, an automated deployer using Pulumi, and also some improvements to the Zstor component of QSFS. The changes to Zstor include better metrics reporting and more efficient use of backend storage when rebuilding files.

As always, thank you for your support on passing this GEP!

Kind regards,
Sabrina on behalf of the ThreeFold Team
