• Extra named arguments given to thmbox are passed to block.
• Fixed spacing bug for unnumbered environments.

Breaking changes

• The supplement (for references) is no longer set in thmenv. It can be passed to the theorem environment directly, along with refnumbering to control the appearance of @references.

Notes

• The 'dummy figure' (used for marking a location for accessing the correct counter) has been replaced with labelled metadata.
