  Fixes a subtle bug where if one language server didn't meet the startup
  requirements, other queued servers wouldn't be handled any more.
• Special-case env.PATH extending to prepend to the original PATH (#1752) (Rafał Chłodnicki)
  In preparation for fixing a subtle bug for helper packages that rely on Node.js
  When you've chosen to use a locally-intalled node local to ST, then any
  possible subprocess spawned by the language server should use that local
  node executable as well.
  The same problem is also present for pip-based helper packages like LSP-pylsp.

As was mentioned in the release notes of 1.5, the following default
configurations are now removed:

• haskell-ide-engine
  -> use haskell-language-server, see lsp.sublimetext.io for instructions
• rlang
  -> use the LSP-R helper package: https://packagecontrol.io/packages/LSP-R

New Helper Packages

• LSP-R: https://packagecontrol.io/packages/LSP-R
• LSP-Deno: https://packagecontrol.io/packages/LSP-Deno

Features and Fixes

• Fix a bug where code actions would be requested for transient
  views (Raoul Wols)
• Clear all status messages when session ends (Janos Wortmann)
  This fixes a bug where if you disable the LSP package while
  a language server is reporting server-initiated progress, the
  progress message would remain visible in the Status Bar.
• CI is once again enabled (#1679) (Rafał Chłodnicki)
• os.path.relpath may throw an exception on Windows (Raoul Wols)
  This fixes a bug where if you use Find References on Windows,
  the response handler could fail by not catching this exception.
• Rename code_action_on_save_timeout_ms to
  on_save_task_timeout_ms (#1728) (Rafał Chłodnicki)
  This allows you to adjust the timeout for formatting as well.

Removed Default Client Configurations

As was mentioned in the release notes of 1.4.0, the following default
configurations have been removed:

• pyls
• dart
• elixir-ls
• flow
• jdtls
• sourcekit-lsp

For all of these, a helper package is available on packagecontrol.io that
automates the boring set up and installation of server binaries.

Deprecated Default Client Configurations

The following default client configs are DEPRECATED and WILL BE REMOVED:

• haskell-ide-engine -> set up haskell-language-server instead, see
  lsp.sublimetext.io for instructions
• rlang -> use the R-IDE package, which provides an LSP client configuration
  under the hood.

New Example Configurations

An example client configuration for "diagnostic-language-server" has been added
to lsp.sublimetext.io. It is a general-purpose language server which allows
you to hook up any command-line linter program or formatter program. It can be
regarded as a replacement of SublimeLinter. There is an example set up for the
shellcheck program to lint your Bash source code.

New Settings

• Use show_code_actions_in_hover to disable code actions in the hover popup.
• Use show_diagnostics_highlights to disable inline diagnostics in the view.

Removed Settings

• diagnostics_highlights_style is replaced by show_diagnostics_highlights.

Features and Fixes

• Draw empty regions as a small horizontal line (Raoul Wols)
• Fix the LSP Development command (#1724) (Arnav Jindal)
• Refine diagnostics presentation (#1710) (Raoul Wols)
• Fix crash on showing code actions (Rafal Chlodnicki)

• Apply all status messages when a SessionView is opened (#1706) (jwortmann)
• Add instructions for shellcheck (#1703) (Rafał Chłodnicki)
• Don't ascii-escape Unicode (Raoul Wols)
  This makes the Flow language server work with non-ascii characters.
• Handle schemes other than the file scheme (#1620) (Raoul Wols)
  This makes the Deno language server work for goto-def and find-references.

Deprecations

We want to remove the default configurations in LSP.sublime-settings
and replace them by helper packages a la SublimeLinter.

The following default configurations are DEPRECATED and WILL BE REMOVED
in a future release:

• "pyls": Use the LSP-pylsp package instead.
• "dart": Use the LSP-Dart package instead.
• "elixir-ls": Use the LSP-elixir package instead.
• "flow": Use the LSP-flow package instead.
• "jdtls": Use the LSP-jdtls package instead.
• "sourcekit-lsp": Use the LSP-SourceKit package instead.

You can now use disabled_capabilities per client configuration.
It's a JSON object (dictionary) of "masked" server capabilities.
For more information on how this works, use the hover info capability
of LSP-json.

Removed settings

  favor of it being a setting per client configuration.
