Additions:

• Added a ??= operator.
  This should prove a more reasonable replacement for #args in GMS2.3.
• Entering . out-of-context now shows the same completion as self. and erases the dot upon choosing a match.
  This allows to utilize the new completion features without increasing verbosity of your code.
  Should come handy for figuring out any problematic spots when updating to GMS2.3.1 (which has built-in functions with no return values to return undefined instead of 0).

Improvements

• You can now open GMS2.3 notes in GMEdit.
• Updated 2.3 function definitions to cover 2.3.1 additions.
• You can now set a keyboard shortcut for reloading GMEdit.
• namedArgument == undefined will now mark the argument as optional (and same for !=).
• “Warn about trying to use result of a script/function with no returned values” now includes built-in functions with known lack of a returned value.
  (uses the dataset from GMLive so should be fairly accurate)

Fixes

• Fixed GMS2.3.1 struct[$ key] accessor not being recognized by the linter.
• Tab no longer unfocuses the search field in Global Lookup.
• The project now reloads when changing GMS2.3 sorting order in Preferences.
• Fixed freshly created 2.3 scripts not being remove-able via GMEdit.
• Fixed function name() {} inside object events confusing the syntax highlighter.
• Fixed @interface always using script name in pre-2.3.
• Fixed a=1b=2 (number+identifier without delimiter) not highlighting right.

Other

I pushed a release with everything but function return value checks and ??= operator to the stable branch.

There is this tendency where I don’t push a build to stable branch because I just added something new, but, let’s be honest, I’m always adding something new.
