Everything is still compatible.
I haven't seen the latest changes that Justin made on the flags, but the
following is true:
- oars produced in older versions of OpenSim can be uploaded in newer
versions, always and forever.
- oars produced in newer versions of OpenSim may or may not be able to
be uploaded in older versions, in general. As of right now, even though
we've rewritten the serialization from the ground up, things are still
compatible in that direction (newer oars->older opensims). As we improve
things (like adding creator information, for example), if we ever come
to a point where compatibility in this direction cannot be ensured,
there will always be a flag to generate older oar formats.
Hope this clarifies things.

Hi folks.
The object serialization format has been changed today, therefore I have been
forced to bump the OAR version from 0.3 to 1.0
This means that 1.0 OARs cannot be loaded into OpenSim 0.7.0.2 and earlier.
Unfortunately, since these earlier OpenSim releases do not check the OAR
version before loading, the loader will probably receive a huge number of
cryptic errors about the xml not being correct, which will be extremely
confusing to everyone.
If you want to produce OARs that can be loaded on OpenSim with current master
code, you must specify --version=0 on the command line, e.g.
save oar --version=0 oars/my.oar
This will create an older (pre-today) style 0.3 OAR which can be loaded into
older OpenSim versions. There is currently no advantage in creating a 1.0 OAR
rather than a 0.3 one.
OpenSim master code and the forthcoming OpenSim 0.7.1 will be able to load both
0.3 and 1.0 OARs.
