v3.0.0 (2017-09-09)

Documentation has been moved to the repository's wiki:
https://github.com/SublimeText/PackageDev/wiki

• All syntax definitions have been rewritten from scratch
  in the new .sublime-syntax format (excluding *-tmLanguage syntaxes).

  As a result, all file paths to the syntax definitions have changed
  and you may have to re-set or re-open any files using them.

  In the process, all snippets and completions have been updated
  and more have been added,
  including auto-completions for all available commands
  and their arguments.

  Entirely new syntax definitions have been added for:

  • new syntax definition files
  • menu files
  • project files
  • tmPreferences files (and generic property lists)

• Settings are linted, have auto-completion and helpful tooltips.

  Settings descriptions and possible values
  are parsed from a setting's comment,
  as long as the package provides one.

  Side-by-side settings also have quick link for editing them.

• New and intelligent templates for old and new resource files.

  With a package's folder added to a project,
  open the command palette with PackageDev: New.

• Some goodies for writing syntax tests:

  • Completions of scope selectors
  • Highlighting of the region that is being tested with the current line
  • Automatic assignment of the specified syntax

• A new command to create a package: PackageDev: Create Package

• All commands have been renamed to include the packagedev_ prefix.

  Remember to update your key bindings, if you have any.

• Other various fixes or tweaks
