Hi Sebb,

The BMPM code has not appeared in a previous release. It is a discrete
addition that doesn't alter any existing code, and as far as I know,
currently no 3rd party code relies upon it. Right now on trunk, it is a

I've no problem with marking it as new or unstable or whatever the right
word is. While it extends StringEncoder, the API is stable. Although there
may be more flux with the finer details of the string you get out for the
string you put in as we fix bugs and update the rule tables, this shouldn't
alter how clients (users of the API) call this code, only the quality of the
results they get back.

Understood. I think this only becomes an issue if/when Encoder becomes
generified, and at that point clearly we need a big version bump, with all
the associated changes, and all encoders and their clients would be equally

Does that help, or have I further muddied the waters?
