and `defn` instead.
* Literal keywords are no longer parsed differently in calls to functions
with certain names.
* `hy.contrib.multi` has been removed. Use ``cond`` or the PyPI package
``multipledispatch`` instead.
New Features
------------------------------
* Added special forms ``py`` to ``pys`` that allow Hy programs to include
inline Python code.
* Added a special form ``cmp`` for chained comparisons.
* All augmented assignment operators (except `%=` and `^=`) now allow
more than two arguments.
* PEP 3107 and PEP 526 function and variable annotations are now supported.
* Added function ``parse-args`` which parses arguments with ``argparse``.
* `hy.contrib.multi` has been removed. Use `cond` or the PyPI package
`multipledispatch` instead.
Other Breaking Changes
------------------------------
* ``HySequence`` is now a subclass of ``tuple`` instead of ``list``.
Thus, a ``HyList`` will never be equal to a ``list``, and you can't
use ``.append``, ``.pop``, etc. on an expression or list.
* `HySequence` is now a subclass of `tuple` instead of `list`.
Thus, a `HyList` will never be equal to a `list`, and you can't
use `.append`, `.pop`, etc. on a `HyExpression` or `HyList`.
New Features
------------------------------
* Added special forms `py` to `pys` that allow Hy programs to include
inline Python code.
* Added a special form `cmp` for chained comparisons.
* All augmented assignment operators (except `%=` and `^=`) now allow
more than two arguments.
* Added support for function annotations (PEP 3107) and variable
annotations (PEP 526).
* Added a function `parse-args` as a wrapper for Python's `argparse`.
Bug Fixes
------------------------------
* Statements in the second argument of `assert` are now executed.
* Fixed the expression of a while loop that contains statements being compiled twice.
* Fixed a bug that caused the condition of a `while` to be compiled
twice.
* `in` and `not-in` now allow more than two arguments, as in Python.
* `hy2py` can now handle format strings.
* Fixed crashes from inaccessible history files.
* The unit tests no longer unintentionally import the internal Python module "test".
This allows them to pass when run inside the "slim" Python Docker images.
* `ap-reduce` now accepts any iterable.
* `ap-reduce` now evaluates its arguments only once.
* Removed an accidental import from the internal Python module `test`.
* Fixed a swarm of bugs in `hy.extra.anaphoric`.
Misc. Improvements
------------------------------
* Drop the use of the long-abandoned `clint <https://github.com/kennethreitz/clint>`_ library
for colors. `colorama <https://github.com/tartley/colorama>`_ is now used instead.
* Replaced the dependency `clint` with `colorama`.
