Announcement text:
----------------------------------------------------------------------
 
 ### Added
 - `\text_titlecase_all:n(n)`
 - `\token_to_catcode:N`
 - Support for symbolic variables in fp input:
   `\fp_new_variable:n`, `\fp_set_variable:nn` and `\fp_clear_variable:n`
 - Support for user-defined functions in fp expressions:
   `\fp_new_function:n`, `\fp_set_function:nnn` and `\fp_clear_function:n`

 ### Changed
 - Refine action of `\text_titlecase_first:n(n)` to be focussed strictly on
   first (relevant) codepoint in the input

 ### Deprecated
 - `\text_titlecase:n(n)` as ambiguous: replaced by `\text_titlecase_all:n(n)`

 ### Fixed
 - Support arbitrary BCP-47 locales for case-changing overrides (issue \#1239)
 - Retain braces when ending titlecasing with some input structures
