 Standard library maintenance:
 * Accurate and correct parsers of Windows and Unix file paths were added to the standard library.
+* `HTMLElement(loc src = |unknown:///|)` was added to position every tag from start to end via the `src` attribute.
+
+The Java model has received big maintenance love and attention:
+* Bumped and upgraded  to the JDT version from Eclipse 2020-03
+* The AST nodes in `lang::java::m3::AST` now all satisfy the AST contract in `analysis::m3::AST`. This means that
+all source code elements are represented in the tree, annotated with `src` origins and ordered from left-to-right as
+they were in the original source file.
+* The constructors: enum, enumConstant, compilationUnit, class, interface, method, field, etc. etc. all received
+extra positional parameters for the concept of modifiers. Before these were modelled as keyword parameters, but 
+that invalidated the earlier mentioned AST contract.
+* An AST and M3 model of the Java 9 module system was added.
+* The `isSuper` boolean was removed from the AST definition of methodInvocation and `new` calls, also to satisfy the AST contract.
+* Java Annotations AST constructors were moved from Expression to Declaration.
+* String based unary and binary operator constructors for Expressions were unfolded to a constructor for each operator, i.e. `plus(Expression, Expression) instead of `binop(Expression, "+", Expression)`
+* TODO
