v3.10.2
This is a bug-fix-only release with improvements to completer and websocket URL.
To upgrade to this release:
-
Make sure your JupyterLab version is 3.2.x. or 3.3.x (3.1.x may work but there is no official support)
-
Update the extension:
pip install jupyterlab-lsp==3.10.2 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=3.10.2 jupyter-lsp=1.5.1
-
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-serverorpython-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 uninstallingpython-language-serverand only then installpython-lsp-server; you may also need to replacepylsoccurrences withpylspin settings if you modified any.

Full Changelog: v3.10.0...v3.10.1
v3.10.0
This release brings:
- support for special formatting of diagnostics tagged as deprecated code (strike-through), or as unnecessary code (faded out):

pylspusers: support forDeprecatedtag is tracked in python-lsp/python-lsp-server#144, and QuantStack/pyls-memestra#53 for memestra - improvements to the signature feature: the text from the signature can be copied, and details can be expanded

- and enables pre-filtering of completions on first invokation, especially useful for TypeScript server (this new behaviour can be disabled with
preFilterMatchessetting if it is not optimal for language servers you use).
Additionally a number of bug fixes and improvements to the codebase are included in this release.
This is the last release under the @krassowski namespace. The next release is planned to be version 4.0 under a new @jupyter-lsp namespace; no action should be needed for users of prebuilt (pip or conda/mamba-installable) version of the extension; other users and dependants will need to install the new package.
To upgrade to this release:
-
Make sure your JupyterLab version is 3.1.x or 3.2.x.
-
Update the extension:
pip install jupyterlab-lsp==3.10.0 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=3.10.0 jupyter-lsp=1.5.1

- squash warnings and errors in web console (#732)

- fixed with enabling of strict null checks:
- previously changing kernels always led to restarting of LSP connection, even if the kernel language did not change; now the connection will be retained if possible
markdownRendereris no longer implicitly required- diagnostics sorting with missing values for
sourceandseveritywas improved and missing values will be consistently shown at the end - diagnostics placeholder was split into

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).

Make sure your JupyterLab version is 3.0.x
