0.3.1 - Altered the interface of om.write from write(path, value, *keys) to write(path, key, value) where key is a metapath. This also affects om.read in that you can no longer provide many metapaths that would become concatenated implicitly. You must now specify a fully resolved metapath, the concatenation thus becomes the responsibility of the user.
Updated to 0.4, altering interface to om.write and om.read rendering them incompatible with 0.3
Change: Dataset: `path` must now include suffix
Serialisation with JSON
History back in shape
Working towards 0.4
