## 0.17.1 - 2024-01-10

- Update references to `parol_runtime@0.20.1` and `parol@0.26`. Please, see
  [CHANGELOG parol_runtime](../parol_runtime/CHANGELOG.md) and
  [CHANGELOG parol](../parol/CHANGELOG.md) for details.

## 0.17.0 - 2023-10-22

- Update references to `parol_runtime@0.20` and `parol@0.25`. Please, see
  [CHANGELOG parol_runtime](../parol_runtime/CHANGELOG.md) and
  [CHANGELOG parol](../parol/CHANGELOG.md) for details.

## 0.16.0 - 2023-09-18

- This release is dedicated to the new error recovery feature in generated parsers.
  The language server itself benefits from this feature and can continue parsing of par files beyond
  the first syntax error. This should improve the overall user experience.

## 0.15.0 - 2023-08-02

- Refactoring of formatting algorithm using the new comment handling feature provided by
  `parol_runtime`. If you experience strange shifts of comments please file an issue.

## 0.14.0 - 2023-07-12

- This release is dedicated to code formatting. A lot of tests have been added to ensure a more
  consistent formatting over different configuration settings.

Please file an issue against formatting if you encounter any problem or have suggestions.

In later releases I plan to refactor the whole formatting algorithm and incorporate the comment
handling provided by `parol_runtime@0.17`.

## 0.13.0 - 2023-06-25

- The `Parol Language Server` now supports a single end comment.
  - This is no restriction of `parol` itself but of the special grammar the language server uses.
    This grammar captures as much comments as possible from the input grammar.
    Feedback is appreciated.
- Support of several new formatting options

  - formatting.empty_line_after_prod
    - Add an empty line after each production
  - formatting.prod_semicolon_on_nl
    - Place the semicolon after each production on a new line
  - formatting.max_line_length
    - Maximum number of characters per line

  This requires vs-code extension `parol-vscode` of version >= 0.1.15.

- Fix of minor formatting behavior problems, like handling of nested EBNF constructs
  - This fixes [#114](https://github.com/jsinger67/parol/issues/114)
