The major changes in this version include a new feature to normalise text as NFC or NFD, the ability to accept decimal code point values, and an overhaul of top part of the user interface.
Added buttons to the Text area to allow conversion of the text to NFC or NFD normalization forms. (You may not notice the change until you list the characters.)
The control panel was also substantially rearranged again to hopefully make it easier for newcomers to see what they can do.
The Code point conversion feature was upgraded to handle decimal code point values.
A single character in the codepoints area or text area is now listed in the lower left panel when you click on 
, rather than in the right-hand properties panel. This is to improve consistency and avoid surprises.
Added a link to the CLDR property demo from the right panel to give access to additional properties.
Improved the parsing of codepoints when surrounded by text in the Code point input field, so that it now works with &#x…; and \u… and \U… escapes.
Jettisoned some unneeded code to reduce download by around 40-50K bytes. Implemented the NFC/NFD feature using AJAX, to avoid putting the download size back up.
When you delete the contents of the text area or the code point area, the associated input field is given focus, so you are ready for input.
A couple more minor bug fixes.
