My patches belong to another discussion thread:

not made by me (at least not this year):

In my own libraries the change would count as API and ABI compatible
with no special consequences for version numbers.

Old applications will continue to work as good or bad as they did before.
If such an application runs into the shortcommings of the deprecated
function cdtext_list_languages(), then the answer to a bug report will be:
Use cdtext_list_languages_v2() and cdtext_set_language_index()
instead of cdtext_list_languages() and cdtext_select_language().

cdtext_select_language() is not deprecated generally. But it assumes a
set of language blocks with all valid and unique language codes.
cdtext_set_language_index() does not depend on such a nice situation.


Have a nice day :)
