**Hi all,**

The second Cylc 8 preview release is now available from Conda Forge. If you’d like to try it, please read the [cylc-8.0a2 release notes](https://cylc.github.io/cylc-admin/release-notes/cylc-8-alpha2).

Some user-facing highlights:

- fully functional Python 3 scheduler and CLI
- terminal UI program `cylc tui` (replaces, and greatly improves on, `cylc monitor`)
- web UI with:
  - integrated multi-workflow side bar (c.f. `cylc gscan` GUI in Cylc 7)
  - tabbed views (tree view, and POC graph view)
  - control functionality, temporarily available via a special “mutations” view
  - event-driven (not polled) global data update

- published to Conda Forge for easy installation

Note this preview release is _not production-ready_ and _may not be secure_ in some ways - it is being made available for testing by interested early-adopters.

The upcoming alpha-3 release will bring even bigger changes (and should be performant for very large workflows); but we’ll advertise those in due course.

The release notes give installation and basic usage instructions. Requests for help, and/or feedback, are welcome via this forum.

Thanks to the Cylc dev team!

Hilary
