We are happy to announce the new release of Golem 0.15.1.

This release adds as a feature, the possibility to restart a single subtask after the whole task hits deadline.

This functionality may be useful if a user is not satisfied with a small part of the rendered image and wants to repeat this particular computation with a different provider.

We have also lowered eth gas cost and predicted gas amount needed estimations, and included fixes to several errors with diverse severity on this new release.

We strongly recommend updating your Golem version to the newer one.

As usual, we encourage you to follow the progress of our project on Golem Kanban, download and test this latest release

Most importantly we would like to remark that your feedback matters, as it plays a key part for us to continue improving Golem.
