v2.3.0-0

This release is made available first as a prerelease to gauge the effects of the TypeScript changes, which add a second optional generic type argument Strict to Document instances. While this change appears to improve the TS usage experience at least with basic patterns, it's possible that it doesn't take into account some usage that would be negatively affected by the change.

Comments are requested, both for and against the change.
