Updated for iLib, and added many new rows for various i18n features. Other libraries slots need to be updated to put the check marks for all these new features.
Yes, that is what I meant.  The reason I called it out separately is that I know that some simple formatters can format numbers with the grouping separators at every 3 digits but don't support the secondary grouping size as given in CLDR. So, I think the idea of group separators at all and the idea of "secondary grouping size" are different levels of support.
