In general each release we make has the same API as previous releases
but may extend it with new functionality too (i.e. it is intended to
be backwards compatible). There have been one or two cases where we
needed to break backwards compatibility because of a bug in the API
but these cases are isolated. So in theory if you develop something
agains 1.0 it should work against current trunk. Do note that 2.0 (our
next major release) will break API compatibility (though that
compatibility will be maintained through the 2.x release series). If
you find specific instances where the api has bee changed by dropping
methods, please let us know as that should be considered a bug
probably.
