v0.3.1

Added

• CircledNumber and DoubleCircledNumber are new systems that uses Unicode
  circled numbers instead of decimal digits. Thank you to @ModProg for this
  contribution!

v0.3.0

Breaking Changes

• HangeulInformal has been renamed to HanjaInformal, its correct name.
• DigitCollection::len and DigitCollection::digit no longer receive a
  digit_index parameter.
• DigitCollection::Fallback is a new associated type that allows a digit
  collection to define a fallback digit set. NoFallback is a new type that can
  be used when no fallback should be used.

Added

• DigitCollection::fixed is a new function that indicates the collection
  should only ever be used to produce a single digit.

Fixed

• CjkHeavenlyStem and CjkEarthlyBranch now fall back to CjkDecimal in a
  fashion that matches the CSS specification. Specifically once the symbols have
  been exhausted, the entire nominal formatting is produced by the fallback
  rather than only formatting the remaining digits with the fallback.

v0.2.2

Changed

• Urdu and Khmer now utilize re-exports rather than type aliases. This
  allows the type constructors to be invoked.

Fixed

• Ethiopic now returns the correct result for 1.

v0.2.1

Fixed

• A compilation error for no-alloc targets has been fixed.

v0.2.0

Breaking Changes

• RomanLowercase has been renamed to RomanLower for consistency.
• HiraganaAiueo and KatakanaAiueo have had Aiueo removed from their names
  to match the CSS naming and reflect modern expectations.
• Urdu has been removed. The Persian Unicode range is reused for Urdu
  numerals, and the different symbols are a result of using an Urdu or Persian
  font.
• DigitCollection::len and DigitCollection::digit now take a digit_index
  parameter, allowing a digit collection to delegate specific digits to other
  implementations.

Changed

• NominalString::INLINE_CAPACITY is now 62, and the type has been optimized to
  avoid zero-initializing data unnecessarily.

Added

• NominalString now implements Clone.

• NominalString::new_reverse() returns an empty string that is optimized for
  push_front operations.

• AdditiveSet is a new NominalSystem implementation that implements additive
  nominal systems. The existing Roman numeral implementation is now utilizing
  this type.

• These nominal systems have been added from the CSS counter-styles spec:

  • ArmenianLower
  • ArmenianUpper
  • Bengali
  • Cambodian
  • CjkDecimal
  • CjkEarthlyBranch
  • CjkHeavenlyStem
  • Devanagari
  • Ethiopic
