First off, depends on what you mean with "UNO API."  One customary 
meaning is the set of UNOIDL entities (mainly) declared in udkapi/ and 
offapi/ .idl files.  (LibreOffice tries to meticulously track any 
incompatible changes it does there, see e.g., the "API Changes" section 
at <http://www.libreoffice.org/download/4-0-new-features-and-fixes/>.)

Another customary meaning is the broader concept of stable interface the 
URE offers, including C ABI, file formats, wire protocols, etc.  My hope 
is that my work on changing the type representation does not affect the 
former, only the latter (file formats etc.).  And, obviously, it will 
need to take care of a backward-compatibility plan.

That said, I can only repeat now what I already said at FOSDEM, that I'm 
going to well document all the changes to any specifications---just like 
I did for any other changes to UNO I did over the last ten years or so. 
 And, as always, any input is highly welcome.

Stephan
