   (#10206)
6. Fix problem with Data Viewer not working when builtin functions are overridden (like max).
   (#10280)
7. Fix interactive window debugging when debugging the first cell to be run.
   (#10395)
8. Fix interactive window debugging for extra lines in a function.

Code Health

1. Add conda environments to nightly test runs.
   (#10134)
