[Opensim-dev] From today, version 1.0 OAR files cannot be loaded into OpenSim 0.7.0.2 and earlier

[Justin Clark-Casey]

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.
