This release includes mostly bug fixes and new experimental features which are opt into. To enable all experimental features, set the environmental variable MUREX_EXPERIMENTAL to any value. Or you can enable specific features individually via config

Breaking Changes

  • None


  • default statement added to switch (this will deprecate catch, albeit catch will remain supported for compatibility)

  • Option to change start directory: config: set shell start-directory $path (where $path is the working directory you wish to start the shell in)

  • onCommandCompletion event no spawns a pty. This allows capturing of stdout while still presenting a tty to the executing process

  • EXPERIMENTAL: preview images. This can be enabled via config: set shell preview-images true

  • EXPERIMENTAL: tty buffer. This can be enabled via config: set shell tty-buffer-enabled true
