Dezyne 2.11: The first standalone release with the Dezyne-IDE, that includes simulation and visualization similar to 2.9.

Dezyne-IDE introduces an LSP [langserver.org](https://langserver.org) server ‘ide lsp’ with basic code completion and goto-definition support.

Dezyne is developed on GNU/Linux, and has been demonstrated to work on the Windows Subsystem for Linux.

## Dezyne-IDE

### Changes in 2.11.0 from 2.9.1

- The integrated Eclipse download has been discontinued.
- Dezyne is now stand alone, client only, serverless, pure GNU Guile Scheme.
- Dezyne-IDE has browser-based views and integrates with any LSP-aware editor.
  - Support for GNU Emacs.
  - Support for Electron-based editors, such as VSCodium.
  - A new command `ide lsp’ provides a stdio-based Language Protocol Server for the Dezyne language.
  - The Dezyne-IDE, view-commands are now subcommands `ide':` ide parse’, ‘ide simulate’, `ide verify',` ide browse’, `ide daemon` , `ide hello', and` ide bye’.

- Views
  - The Trace view now places the buttons with the port’s time line.
  - The State view was removed. The state view in 2.9 (and earlier) was often incomplete or incorrect. A complete and correct State view will return.
  - The Table views were removed.
  - The watch window has been integrated in the sequence diagram.
  - The watch window itself is now deprecated.
  - Diagram click is optionally (ide lsp --relay-daemon) mapped to an LSP publishDiagnostics message, this will likely change in the near future.

## Dezyne core

### Changes in 2.11.0 from 2.10.1

- Commands
  - A new command `dzn language’ supports DZN-language completion and lookups.
  - The commands `dzn cat and` dzn ls’ have been removed.

- Parser
  - A well-formedness check was added for trigger, action, and function-call arguments.

# Changes in 2.10.1 from 2.10.0

- Usability
  - The dzn command now exits gracefully when given an unknown command.
  - The dzn-mode for GNU Emacs is now a major mode called “Dezyne”.

- Parser
  - Parse errors in imported dzn-files now show the import inclusion path.
  - Using newlines between `dollar'-expressions and toplevel` dollar’-statements is now an error.

- Code generation
  - Performance has been improved.
  - The C++ code generator is now prepared for C++20: The dzn::port::meta fields are renamed to “provide” and “require”.
  - The Scheme code generator uses the “namespace to module” feature. This code generator is experimental, and not available in the regular binary release.
  - The JavaScript code generator uses the “namespace to module” feature. This code generator is experimental, and not available in the regular binary release.

- Documentation
  - The infocenter has been converted to texinfo and is now included in the release.

- Noteworthy bug fixes
  - Fixed a regression of using two different types of async interface in one behaviour.
