The LaTeX Team submitted an update to the

l3kernel

package.

Version number: 2022-01-12 License type: lppl1.3c

Summary description: LaTeX3 programming conventions

Announcement text: ----------------------------------------------------------------------

## [2022-01-12]

### Added - Support for validity scope for keys - `peek_remove_filler:n` - `prop_to_keyval:N` - ` egex_match_case:nn(TF)`, ` egex_replace_case_once:nN(TF)`, ` egex_replace_case_all:nN(TF)`

### Changed - Policy change: functions will no longer be removed after deprecation, thus the Lua functions noted below are the *last* 'stable' code to be removed from `l3kernel` after deprecation - Allow indirect conversions between colorspaces through fallback models - Move some color functions from `l3backend`

### Deprecated - `peek_..._ignore_spaces:N(TF)` functions - `sys_load_deprecation:` - Option `undo-recent-deprecations`

### Removed - Lua functions in `l3kernel` table
