We are pleased to announce the release of Eucalyptus 2.0! Now available for immediate download, this latest version of the Eucalyptus open source cloud introduces several new features, including iSCSI support for EBS volumes, S3 versioning, virtio support for KVM hypervisors, and new administrator tools. Now updated to Eucalyptus 2.0, we welcome you to testdrive the new release on our Community Cloud (ECC).

Eucalyptus 2.0 provides packages for an expanded set of Linux distributions: Debian, CentOS, OpenSUSE, and, for the first time, Fedora. Please see our documentation for comprehensive installation and configuration instructions pertaining to your distribution. Eucalyptus 2.0 is already available to Ubuntu users via official repositories as the core element of the UEC (Ubuntu Enterprise Cloud), which is powered by Eucalyptus.

In coordination with the release of Eucalyptus 2.0, we are pleased to announce the availability for immediate download of Euca2ools 1.3, Eucalyptus' EC2-compatible client tools. This new version features extended coverage of the AWS EC2 API, compliance with newer dependency packages, Windows support, and numerous small improvements.

And there's more for Eucalyptus contributors! To make submitting your patches easier, we have introduced a new patch submission process that lets you interact more directly and intuitively with Eucalyptus engineers and easily check the progress of your patches. Our Web site sports new graphics and navigation to help you reach essential information quickly. And we have rewritten important parts of our documentation -- including entirely revised Eucalyptus Network Configuration and Troubleshooting sections -- to help make it easier for you to deploy, configure, and maintain your Eucalyptus cloud.

Finally, with the release of Eucalyptus 2.0, our nightly builds are back! If you want to check out the latest Eucalyptus development branch, the nightly builds are for you.
