• New Create Constant quick fix : whenever a variable name cannot be resolved, there is now a quick fix that offers to create a constant with that name.
• New quick assist for introducing blocks : quick assist lets you quickly convert a single statement of an 'if' statement into a block. Set the cursor to the 'if' and press Ctrl+1.
• Incremental content assist : in the Java editor, you can now use shell-style incremental completion.
