### 29.0.1

* Fix broken `s`/`t` variants for `U+01BE`. (#2223).

### 29.0.0

* \[**BREAKING**\] Add separate serifed variants for digits `2` through `5`. As a result, current variants are partially renamed and reordered (#1965). Change of variant names:
  - `two`.`straight-neck` → `two`.`straight-neck-serifless`
  - `two`.`curly-neck` → `two`.`curly-neck-serifless`
  - `three`.`flat-top` → `three`.`flat-top-serifless`
  - `four`.`closed` → `four`.`closed-serifless`
  - `four`.`closed-non-crossing` → `four`.`closed-non-crossing-serifless`
  - `four`.`semi-open` → `four`.`semi-open-serifless`
  - `four`.`semi-open-non-crossing` → `four`.`semi-open-non-crossing-serifless`
  - `four`.`open` → `four`.`open-serifless`
  - `four`.`open-non-crossing` → `four`.`open-non-crossing-serifless`
  - `five`.`upright-arched` → `five`.`upright-arched-serifless`
  - `five`.`upright-flat` → `five`.`upright-flat-serifless`
  - `five`.`oblique-arched` → `five`.`oblique-arched-serifless`
  - `five`.`oblique-flat` → `five`.`oblique-flat-serifless`
* \[**BREAKING**\] Reorder of glyph variants:
   - Influenced characters: `I`, `U`, `Z`, `i`, `l`, `u`, `z`, Greek Lower Mu (`μ`), Micro Sign (`µ`).
* \[**BREAKING**\] Quasi-proportional will now use a six-unit system instead of four. Metrics of various letters (`f`, `t`, `r`, `m`, `w`, etc.) are adjusted.
