Warning: Hy 0.17.x will be the last Hy versions to support Python 2, and we expect 0.17.0 to be the only release in this line. By the time 0.18.0 is released (in 2020, after CPython 2 has ceased being developed), Hy will only support Python 3.

Removals

  • Python 3.4 is no longer supported.

New Features

  • Python 3.8 is now supported.
  • Format strings with embedded Hy code (e.g., f"The sum is {(+ x y)}") are now supported, even on Pythons earlier than 3.6.
  • Added a special form setx to create Python 3.8 assignment expressions.
  • Added new core functions list? and tuple.
  • Gensyms now have a simpler format that's more concise when mangled (e.g., _hyx_XsemicolonXfooXvertical_lineX1235 is now _hyx_fooXUffffX1).

Bug Fixes

  • Fixed a crash caused by errors creating temporary files during bytecode compilation.
