### We have released cylc-flow 8.3.4

(release may take a couple of hours to appear on conda-forge)

This includes several bugfixes including:

- Prevent duplicate job submissions.
- Prevent clock-expired tasks from being re-submitted by `execution retry delays`.
- Fix an issue where the broadcasted platform could be ignored if all hosts for the platform are down.

### How to update site installations

Sites should create a new environment for this release and manage parallel installations using the provided [wrapper script](https://cylc.github.io/cylc-doc/stable/html/installation.html#managing-environments).

### How to update stand-alone installations

```auto
# First shut down running workflows:
cylc stop '*'

# For Conda managed environments:
conda update 'cylc-flow=8.3.4'

# For Pip managed environments:
pip install 'cylc-flow==8.3.4'

```
