## [2019-01-28] ### Added - Global versions of box affine functions, e.g. `\box_grotate:Nn` - Global versions of box size adjustment functions - `\box_(g)set_eq_drop:NN`, `\(h|v)box_unpack_drop:N` - `\file_get:nnN` and `\file_get:nnNTF` - Experimental functions `\sys_shell_get:nnN` and `\sys_shell_get:nnNTF` ### Changed - `\char_generate:nn` now always takes exactly two expansions - Move `\prg_generate_conditional_variant:Nnn` to stable - Renamed experimental `\box_trim:Nnnnn` and `\box_viewport:Nnnnn` as `\box_set_trim:Nnnnn` and `\box_set_viewport:Nnnnn`, respectively ### Deprecated - `\box_(g)set_eq_clear:NN`, replaced by `\box_(g)set_eq_drop:NN` - `\(h|v)box_unpack_clear:N`, replaced by `\(h|v)box_unpack_drop:N - `\tl_(g)set_from_file(_x):Nnn`, replaced by `\file_get:nnN` ### Fixed - Scope treatment of `\box_set_dp:N`, _etc._ - In (u)platex: detection of spaces in `\tl_rescan:nn` and related functions ### Removed - Experimental function family `\tl_(g)set_from_shell:(N|c)nn` (replaced by `\sys_shell_get:nnN`)
