This release updates the Dhall version to 17.0.0, which supports empty quoted labels (#89) and removes Optional/build
and Optional/fold
(#91). It also fixes an issue with escaping for quotation marks in Text
values in dhall-circe (see #41 and #93).
All artifacts in this release are verified to be binary compatible with 0.3.x (but please note that some programs may normalize or type check differently than they did with 0.3.x because of the Optional
removals).
