We are pleased to announce the first release candidate for Cylc 8.
This release is suitable for early adopters and acceptance testing.
Note: Due to an issue with Jinja2 it is necessary to specify a version range for “markupsafe” if installing with pip:
$ pip install 'markupsafe<2.1' cylc-flow
Please raise questions about migration issues or feedback issues in the Cylc 8 migration category:
Cylc 8.0rc1 will be followed by further release candidates where we will attempt to address feedback and fix any issues reported. We will continue to develop new Cylc features after the official 8.0.0 release.
The web-based GUI (cylc-ui) will see a steady trickle of features in the following release candidates and beyond into future Cylc 8 releases. The familiar Cylc 7 “dot” and “graph” views will arrive in a future Cylc 8 release along with static graph visualisation, multi-selection and other improvements.
Workflows run with earlier beta versions cannot be restarted with Cylc 8.0rc1 due to a database change.
The Cylc UI Server configuration file path has changed from
~/.cylc/uiserver/jupyter_config.py. The same for the site-config where
hub has been replaced by
