I hope too !
That's why we're keeping the code not really public (only developpers can use
it) as the format is still subject to changes (see yesterday's updates and I
still didn't have a look to your LFE email).
Right now I can't think of any changes on the EBML part, which is highly
flexible and should not have any forward compatibility problems (new basic types
should be added to handle other complicated forms of the format).
On the other hand, matroska defines a lot of stuff in the standard. And not all
of them are tested and can be tested soon. So the spec freezing will not happen
very soon (or at list only for the working/tested parts). Once the first beta
code is released to the general public (with tools using that code) all the
introduced/used elements should be considered as frozen.
