   3 ## 2.0.0
   4 - Upgrade to TypeScript 4 and simplify Form declarations.
   5 - Add support for overlay modules:
   6     - Overlay modules inherit all the forms of the parent module, but specific forms can be replaced
   7       if they have changed since the prior year.
   8     - TaxReturns now have `constants` property, to inject inflation-adjusted constants, which is
   9       what most year-to-year changes require.
  10     - Add the **fed2020** module as an overlay to **fed2019**.
  11     - Add the **fed2021** module as an overlay to **fed2020**.
  12     - Some common values on `Form1040` are now accessed symbolically in referencing forms, to make
  13       them immune against year-to-year line number shifts.
  14 - The `Line` class now supports a `LineOptions` to hold less-common options.
  15     - Currently there is only a `formatType`.
  16 - Add limited support for ISO options exercises to AMT/Form 6251.
