Normative Changes

• Add UnicodeExtensionSubtags abstract operation.
• Change relevantExtensionKeys to a List.
• Unicode 8.0 is now required for 3rd Edition. This implies slight changes at least to white space rules and case mappings. The committee intends to update this requirement regularly as Unicode releases yearly.
• Added Intl.getCanonicalLocales().
• Correcting Annex B Regular to reflect another change between 1st and 2nd edition.
• Ensure ResolveLocale() with BestFitMatcher() returns valid language tags.

Editorial Updates

Too numerous to mention all of them. Most notable, arrangements in the structure in preparation for new features planned for 4rd Edition.
