## 4.5.4

- Remove infrequent and rather useless "Failed to parse" diagnostics (and thereby the `HIGHLIGHT_PARSING_ERRORS` and `highlightParsingErrors` configuration option) – the tree sitter parser is actually rather good at error recovery. Note that these messages will now be shown in the log. https://github.com/bash-lsp/bash-language-server/pull/686

## 4.5.0

- Include 30 snippets for language constructs (e.g. `if`), builtins (e.g. `test`), expansions (e.g. `[##]`), and external programs (e.g. `sed`) https://github.com/bash-lsp/bash-language-server/pull/683

## 4.2.1

- Add support for resolving loop variables https://github.com/bash-lsp/bash-language-server/pull/653

## 4.2.0

- Improve heuristic for resolving variables by taking the scope into account, both locally and when sourcing files. https://github.com/bash-lsp/bash-language-server/pull/649
- Support client responding with `null` for `workspace/configuration`. https://github.com/bash-lsp/bash-language-server/pull/650

## 4.1.3

- Correctly parse environment variable `BACKGROUND_ANALYSIS_MAX_FILES`, although clients should migrate to the new configuration system (see info in the 4.0.1 release). https://github.com/bash-lsp/bash-language-server/pull/640

## 4.1.2

- Correct ShellCheck `source-path` argument to support following sources based on the local folder of the file and the workspace root.

## 4.1.0

- Symbols across files are now only included based on sourced files (using non dynamic statements like `source file.sh` or `. ~/file.inc`) instead of including symbols from all files in the workspace. We now also support jump-to-definition on the file path used in a source command. The new behavior can be disabled by turning on the `includeAllWorkspaceSymbols` configuration option. https://github.com/bash-lsp/bash-language-server/pull/244

## 4.0.1

- **Breaking**: Drop support for Node 12, which reached its official end of life on April 30th 2022. Doing so enables new features. https://github.com/bash-lsp/bash-language-server/pull/584
- ShellCheck: support code actions, remove duplicated error codes, add URLs and tags, support parsing dialects (sh, bash, dash, ksh) but still fallback to bash, enable configuring ShellCheck arguments using the `shellcheckArguments` configuration parameter (legacy environment variable: `SHELLCHECK_ARGUMENTS`)
- Support workspace configuration instead of environment variables which enables updating configuration without reloading the server. We still support environment variables, but clients **should migrate to the new workspace configuration**. https://github.com/bash-lsp/bash-language-server/pull/599
- Allow disabling background analysis by setting `backgroundAnalysisMaxFiles: 0`.

## 3.3.1

- Fix missing documentation for some help pages https://github.com/bash-lsp/bash-language-server/pull/577

## 3.3.0

- Enable ShellCheck integration to be disabled from the configuration. The default configuration used should be "shellcheck". https://github.com/bash-lsp/bash-language-server/pull/571
