==============================

Removals

New Features
------------------------------

* New contrib module `pprint`, a Hy equivalent of `python.pprint`.

Bug Fixes
------------------------------

0.19.0 (released 2020-07-16)

* Python 3.9 is now supported.

Bug Fixes
------------------------------
* Improved support for nesting anaphoric macros by only applying
  symbol replacement where absolutely necessary.
* Quoted f-strings are no longer evaluated prematurely.
* Fixed a regression in the production of error messages for empty
  expressions.
* Fixed a scoping bug for code executed with `hy -c`.
