Update changelog with Berts latest addition

Use xStrdup instead of xMallow and strncpy

    StringUtils.c: In function ‘String_split’:
    StringUtils.c:86:7: error: ‘strncpy’ specified bound depends on the length of the source argument [-Werror=stringop-overflow=]
       86 |       strncpy(token, s, size + 1);
          |       ^
    StringUtils.c:84:18: note: length computed here
       84 |       int size = strlen(s);
          |                  ^
