What version of JetBrains' Pug Plugin is being used?

I cannot confirm anywhere in the Plugin description of what version of Pug (Ex-Jade) syntax this plugin is using. I am using the following code (which is legitimate Pug v2, but the plugin is marking it as such:

L28 Error: Expecting newline or semicolon

L32 Error: Must be lvalue

L34-L37 Warning: Expression Statement is not assignment or call

L40 Error: Expression expected

The Syntax is 100% to my knowledge.
