Hi again,

Famous last words:

> These [7.8.5 and 7.9.0] will _probably_ be the final cylc-7 releases.

Cylc-7.8.6 and Cylc-7.9.1 are now [available to be downloaded](https://github.com/cylc/cylc-flow/releases).

Cylc-7.8.6 has two more important bug fixes on top of 7.8.5. One prevents automatic cycle point format conversion when using `cylc suite-state` or the `suite_state` xtrigger, if the target suite uses the default format but the downstream command or suite does not; the other can (depending) cause a lot of spurious warnings to be logged at restart, for large long-running workflows.

Cylc-7.9.1 is the same as 7.8.6 except that the bundled Jinja2 version has been upgraded to 2.11.1, which allows us to report the right line number for all Jinja2 errors.

Cylc-7.9.x requires Python 2.7.  
Cylc-7.8.x works with Python 2.6 or 2.7.

If you are not stuck with a legacy Python 2.6 system you should go straight to Cylc-7.9.1.

Details:

- [cylc-7.8.6 changes](https://github.com/cylc/cylc-flow/blob/7.8.x/CHANGES.md#cylc-786-2020-05-14)
- [cylc-7.9.1 changes](https://github.com/cylc/cylc-flow/blob/branch-7.9.1/CHANGES.md#cylc-791-2020-04-22)

These will _probably_ be the final cylc-7 releases. 😬

A new preview release of Cylc 8 (Python 3 based, with a web UI) will be announced soon.
