v3.9.0

This release includes highly anticipated bug fixes and improvements:

• fixes completions of paths in Python,
• fixes kernel completions in R,
• improves the signature feature, which will now:
  • highlight the active argument
  • be displayed above the active line to avoid conflicts with completer
• enables you to disable specific features, which may improve performance by reducing LSP server workload

before	after

This is the last minor release using @krassowski npm organization. Subsequent major and minor releases will use new @jupyter-lsp organization. This is the last minor release targeting JupyterLab 3.0, subsequent releases will target 3.1 and 3.2 versions.

To upgrade to this release:

1. Make sure your JupyterLab version is 3.0.x, 3.1.x or 3.2.x (this is the last minor release with user support for 3.0).

2. Update the extension:

   pip install jupyterlab-lsp==3.9.0 jupyter-lsp==1.4.1
   # or, for conda:
   # > Please note that conda packages may take a day or two since release before becoming available!
   # conda install -c conda-forge jupyterlab-lsp=3.9.0 jupyter-lsp=1.4.1

3. Note:

• If installing this extension for the first time, please read the full installation instructions as language servers of your choice need to be installed too, and additional configuration can make your experience smoother.
• If you wish to use jedi-language-server or python-lsp-server, please make sure to upgrade IPython to 7.20 or newer.
• If you wish to migrate to python-lsp-server (which is encouraged), please start by uninstalling python-language-server and only then install python-lsp-server; you may also need to replace pyls occurrences with pylsp in settings if you modified any.
