Renku

------

Renku ``0.20.0`` tidies up the RenkuLab session start sequence, as well as an assortment of improvements and bug fixes.

User-Facing Changes
~~~~~~~~~~~~~~~~~~~

**✨ Improvements**

* 🚀 **UI**: We tidied up the session launch sequence to have a unified appearance, regardless of where on RenkuLab you start your session from. Sessions also have better logs and error handling.
* 🎨 **UI**: The RenkuLab login and logout pages have been updated with the latest styling.
* 💬 **Renku CLI**: When you run ``renku save`` in a clean but unpushed repository, ``renku`` now informs you that it has pushed changes to the remote, rather than just saying that there were no changes to save.

**🐞 Bug Fixes**

* 💔 **Renku CLI**: Fixed an issue where ``renku workflow compose`` would break ``renku workflow list``.
* 🍴 **UI**: Fixed the Project name field getting reset when forking a project.
* 📃 **UI**: Fixed issues with downloading session logs.
