Release 2022.05.100

2022.5.100 (7 June 2022)

Enhancements

1. Document context keys for keybinding 'when' clauses.
   (#6573)
2. Alert boxes of the form <div style="alert alert-danger"> are now styled as colored boxes, to match how they are in Jupyter.
   (thanks Eric Wieser)
   (#8399)
3. Enabled the Interactive Window in web.
   (#9717)
4. Enabled the Variables Viewer in web.
   (#10154)
   However, neither the DataFrame viewer nor the Plot viewer are enabled in this release.
   (Tracking: #9665)

Fixes

1. Validate remote Jupyter Server connections when attempting to start a kernel.
   (#8043)
2. Fix to provide autocomplete inside of quoted strings. This fix also enabled a setting to allow the use of Jedi for completions in a kernel, but should be used with caution. Jedi can hang the kernel preventing exeuction from happening.
   (#8893)
3. Clear locally saved connection info when we run the server clear command.
   (#8956)
4. Ensure the format progress message disappears once export has completed.
   (#9112)

   (#9167)
6. Show the export commands for non-python notebooks.
   (#9571)
7. Makes progress indicators appear for web extension when connecting to kernels.
   (#9784)
8. Support reopening a notebook in web browser and having it remember its original kernel.
   (#9826)
9. Allow usage of the jupyter API in stable builds so Juptyer Power Toys can use it.
   (#9868)
10. Support notebook debugging in the web extension.
    (#9973)
11. Support widgets that can be downloaded from a CDN in the web extension. Non CDN widgets will come later.
    (#9984)
12. Add editor context key support into the web extension.
    (#9990)
13. Fix problem with PYTHONNOUSERSITE being set even when not desired. There's a setting now that will set this environment variable on kernel launch if it's needed: jupyter.excludeUserSitePackages.
    (#9995)
14. Don't show the python extension install ui when auto starting kernels.
    (#10011)
15. Support standard ipywidgets in the web extension.
    (#10051)
16. When connecting to a remote Jupyter server with a password you will not have to input the server URL twice to have it apply anymore.
    (#10103)
17. Fix clicking on links for error callstacks to open the same original python file instead of a new one.
    (#10149)
18. Gracefully handle failures when attempting to convert ANSI codes to HTML in large error output within the errors renderer.
    (#10172)
19. Fix 'go to source' to work again in the interactive window.
    (#10205)
20. Fixes run by line not stopping on any lines.
    (#10207)
21. Fix Jupyter: Variables hiding when closing a notebook or an interactive window.
    (#10209)
22. Fix error renderer to return tracebacks.
    (#10239)
23. Fix problem with interactive window links being off by one.
    (#10283)

   (#5478)
2. Add tests to verify notebook metadata is in a notebook.
   (#5601)
3. Add telemetry test to verify we output a specific set for different operations.
   (#6883)
4. Added a Performance test to test and ensure expected performance characteristics.
   (#7437)
5. Don't skip code completions when the server is busy. Instead let it timeout if the server doesn't come back.
   (#9797)
6. Add test for remote https jupyter servers.
   (#9844)
7. Change document to notebook off of NotebookEditor class due to API change.
   (#10083)
8. Dataframe tests were failing when Pylance was updated to return the 'Name' column for a dataframe.
   (#10259)

38. Fix for intellisense breaking after typing a magic into a cell other than the first.
    (#8830)

   (#3200)
3. Consolidate requirements.txt files into a smaller set.
   (#3992)
