Fixed
- The ability to control substitutions, and thereby (for example) use
document attributes to reduce duplication, was broken. Thanks to
Jared Reisinger for noticing
this and contributing a fix!
Added
- A new predefined value,
svg-attrs, which starts out as an empty
map, but can be redefined to add arbitrary SVG attributes to the
top-level SVG node of your diagram (for example, to set a background
color for the entire diagram).
