Unable to modify the sites it works with, preventing me from using it with the private github server I need to use. Unable to comment on the quality of the plugin otherwise

Parse error on line 2: ...TD subgraph Sources["Project Groups"] ----------------------^ Expecting 'SEMI', 'NEWLINE', 'SPACE', 'EOF'.... Please update the mermaid version this uses, its got to be a few years out of date.

It's a nice extension, but the underlying version of mermaid hasn't been updated in a while and is missing newer abilities. This make it less useful as it doesn't adhere to the current spec.
