Drop binaries into your tank here.
Tank is now using TiddlyWeb v 2.3.0. That version supports the media-type application/vnd.tiddlyweb+json. This makes it possible to PUT a tiddler with a type attribute of application/json and GET it back later. In earlier versions this was not possible.
tiddlywebplugins.links has also been updated so that links to targets containing spaces are properly registered in the data store.
