Fedora 27 Beta has been released. Here the announcement:

We're excited to announce the release of Fedora 27 Beta.

A short list of changes:

The Workstation edition of Fedora 27 Beta features GNOME 3.26.

LibreOffice is updated to LibreOffice 5.4.

Fedora Atomic 27 now defaults to a more simple container storage setup, furthermore offer containerized Kubernetes, flannel and etcd.

We are also simultaneously releasing 64-bit F26 Beta for ARM (AArch64) and Power (both little and big endian) architectures.

Fedora 27 Beta Server is intentionally delayed while we incorporate additional modularity changes, and is planned for release in approximately a month.

Also be aware that we are missing i686 (32-bit Intel architecture) images for this release; this is due to a bug in image checksum creation and which we will fix it by the final release. If you are interested in testing Fedora 27 Beta on i686, wait for upcoming nightly images — or update from Fedora 26.
