### We have released cylc-flow 8.6.2, cylc-uiserver 1.8.2 and rose 2.6.3

The Cylc UI Server release provides several updates to the GUI, notably:

- The workflows sidebar now displays indicators if there are any held or retrying tasks in the active window.
- Task state filters now include task modifiers so we can now filter for “held” or “retrying” tasks.
- Task ID filters now accept globs.
- The command editor forms can be opened in a new tab (with the exception of broadcast).
