This release contains a host of bug fixes and improved conformance to the spec.
The most notable change, however, is the relaxing of the closed struct constructs.
Relaxed closed structs
With the previous release, each struct literal in a definition was treated strictly as closed.
This turned out to be both tedious and counter-intuitive.
This led to a spec change and corresponding different implementation where
a definition is only closed once it is referenced.
This means that merging literal structs defined within a definition works exactly
like unification of regular structs up to the point they are referenced.
Features
There are several builtins added, including in the list and regexp packages.
The latter added builtins to extract fields from strings into a struct using named groups.
