[Zoo-discuss] ZOO-Project 2.1.0-rc1

[Gérald Fenoy]

Hello,
I am glad to announce that the ZOO-Project-2.1.0 release candidate 1is now available online [1].

This new ZOO-Project release contains new features and fixes, listed below.

This release, specifically the Docker image associated with the ZOO-Project-DRU Helm chart version 0.9.1 [2], includes a set of Python packages ([3]) available on pypi.org. They were part of last year's Google Summer of Code contributions ([4]). The zoo-runner-common and zoo-template-common Python Packages are now up to date, tested, and integrated into the available runners and templates.

With this release, we introduce the skaffold.yaml configuration file [5], which can be used to easily deploy the ZOO-Project-DRU Helm chart with Calrissian, Argo-Workflows, or WES support on your Kubernetes cluster. A full-featured version of the configuration file is also available on the charts repository, which has a higher release rate.

The EOAP [6] - CWL Custom Types [7] are supported, and a new client, nuxt-client [8], was created.

The work was funded by the EOEPCA+ project [9].

New Features and Fixes:

    • Add support for the /jobs/{jobId}/results/{outputId} endpoint

The release was initially made yesterday, but an issue with the Zenodo integration was identified and needed to be updated. As a consequence, we decided to re-release, which solved the Zenodo publication issue.

Also, we invite all contributors to this release to add themselves to the CITATION.cff [10] or update their personal information (such as affiliation) if needed. If you have an ORCID, you can also add it to your information; you can see how it looks for contributors that have an ORCID on this page: [11].
