## [2025-03-10]

### Added
- `\text_words_map_function:nN`
- Variants `\tl_head:e` and `\tl_tail:e`
- `l3tl` functions (and variants) which trim spaces from only one side
  (issue \#1673):
  - `\tl_trim_left_spaces:n`, `\tl_trim_left_spaces_apply:nN`,
    `\tl_(g)trim_left_spaces:N`
  - `\tl_trim_right_spaces:n`, `\tl_trim_right_spaces_apply:nN`,
    `\tl_(g)trim_right_spaces:N`

### Changed
- `\fp_set_function:nnn` and `\fp_set_variable:nn` now raise errors on
  undefined (fp) identifiers (issue \#1700)

### Fixed
- Avoid low-level error if keys are given without a module (issue \#1254)
