AFAICT, speaking of "darcs-2-format" is misleading: the latest major
version of darcs introduces two new tecnologies, a new format
("hashed") which brings several benefits (faster, obfuscated pristine,
centralized cacheability, ...) and a new semantic ("darcs-2"). The
latter is (currently) built on top of the new hashed format.

While darcs 2.0 is able to exchange patches between repositories with
a different format, the same can't happen if the repositories have
different semantics: as explained here and there, changing semantic
alters *how* darcs operates on the patches, for example how it detects
conflicts between them.

hth,
ciao, lele.
