v3.9.3

This release contains only a minor workaround for translation strings. The minimum supported Python version is now Python 3.7 as Python 3.6 reaches end of life this week.

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==3.9.3 jupyter-lsp==1.5.1
   # 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=3.9.3 jupyter-lsp=1.5.1

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.

v3.8.0

This release improves user experience when troubleshooting server extension installation (thanks @icankeep) and installation of specific language servers, improves performance of completer (note: this change will be only noticeable by users already using fast language servers), and fixes a few other bugs. It is accompanied with an update of jupyter-lsp which was extended to support listing all known language servers (even when not installed) and specifying language server installation troubleshooting information; external providers of language server specification who use ShellSpec may need to update is_installed() method signature (more details in the full changelog).

v3.5.0

This release provides notable improvements and bug fixes to the completion feature and handling of IPython magics:

• %%bigquery IPython cell magic is now supported
• detail information about the completion is now shown instead of the type by default; if no detail is available, then type or source ("Kernel" for kernel completions) is shown instead
  
• new settings are available for completer:
  • caseSensitive: you can make matching of completions case-insensitive by setting it to false
  • includePerfectMatches: you can ask completer not to include perfect matches by setting it to false
  • labelExtra: you can revert to old behaviour of showing the type next to the label, or change it to showing source, or only detail.
    
• for extension developers:
  • RegExpForeignCodeExtractor's extract_to_foreign was split into foreign_capture_groups and foreign_replacer
  • minimal functional extractor and code overrides APIs are now exported; these APIs can be subject to change in future releases
  • the completions code was refactored to make it possible to support integration with other completion providers in the future
