    Celebrating 1000 github stars!

    New Features:

    • File type configuration - File types are now user configurable. Flow comes with a built-in
      list of file types that you can now modify and save to the configuration directory with the
      Edit file type configuration command. You can also create whole new file types simply by adding
      new files to the configuration directory in the file_type folder. The file type configuration
      defines the name, icon, description, formatter and language server, extensions and first line
      matching rules for a file type.

    • Auto Save - Enable auto save for the current buffer with the Toggle auto save command. This
      will automatically save the current buffer on every change. Debounce time is the currently
      configured frame rate. You can also enable auto save globally with the enable_auto_save
      configuration option, and limit which file type have auto save automatically enabled with the
      limit_auto_save_file_types configuration option (which is a list of file types, e.g.
      ["zig","rust"])

    • Highlight columns - Use the Toggle highlight columns (toggle_highlight_columns) command
      (bound to shift+f11 in flow mode) to enable a background dim effect at the configured column
      positions. The columns to highlight are configured via the highlight_columns configuration
      option.

    • Smart insert & delete - Brace pairs like (), [], {} and "" are now handled intelligently like
      in most code editors. Also, leading whitespace is now intelligently deleted in indent_size
      steps.

    • Format on save toggle - Format on save can now be toggled for the current buffer with the
      Toggle format on save command (toggle_format_on_save).

    • Git support - The status bar now shows a summary of the project's git status include current
      branch, number of changed files and number of unpushed/unpulled/stashed commits. Also, Flow now
      respects all of git's file ignore machanisms. Diffs do not yet use git, but that is planned.

    • Auto create parent directories - Flow will now automatically create parent directies if
      necessary when creating new files.

    • Tilde expansion - The Open file and Save as commands now correctly support expanding ~
      to the user's home directory.

    • Improved panic handling - Flow now has much improved panic handling and will leave the
      terminal in a known good state for all panics and segfaults. Additionally, release and nightly
      builds are now available with full debug information that will produce fully detailed backtraces
      on crash. This should help catch and fix those rare but pesky crashes. Please submit issues!
      Additionally, there is a configuration option to automatically start and connect gdb to a
      crashing flow instance. (linux only)

    • Terminal support - Flow now supports the kitty explicit text width protocol. This improves
      unicode character rendering on terminals that support it and superceeds wcwidth when available.

    • Language server protocol - Flow language server protocol backend is now fully asynchronous.
      This means that slow language servers cannot cause pauses while editing.

    • Language support

      • Added powershell syntax highlighting
      • Added hurl syntax highlighting
      • Added rpmspec syntax highlighting
      • Added protobuf syntax highlighting
      • Added uxntal syntax highlighting
      • Added C# formatter (csharpier)
      • Added PHP language server (intelephense)

    • Themes

      • Themes can now be customized with the Customise theme command
      • Added the entire base16 theme collection
      • Added the hypersubatomic theme

    • Home screen - The home screen text and list of commands can now be customized. Also, the
      current build version and build type are now shown in the bottom right corner of the home screen.

    • tree-sitter - Queries are now biniary compiled and stored in the flow executable. This
      greatly improves load times and reduces binary size. Also, incremental tree-sitter parsing is
      now checked for parsing errors and will fallback to a full re-parse if errors occur.

    • Integer arguments - Flow now supports integer arguments to many commands similar to emacs and
      vim. Related bindings have been added to Flow, Emacs, Vim and Helix modes. Pending integer
      arguments are shown in the status bar.

    • Vim mode improvements - Insert mode now produces automic undo steps, much more like Vim. Many
      vim mode bindings have been improved to more closely match Vim in their behaviour. Visual line
      mode was added.

    • Helix mode improvements - Many helix mode bindings have been improved to more closely match
      Helix in their behaviour.
