Using `make update-json`, all json descriptions have been update. Quite interesting to see that there are plenty of new ones which are giving 404 when queried. An actual bug, or something I should look into ?
Also update the latest source-code, which is just a cleanup.
This helps make keep track of what was successfully published to crates.io
As we are now back to serde 0.6, the patch-level was upped too.
