-   * The unquote-splice or ~@ form now accepts any false value as empty.
+   * `def` is gone; use `setv` instead
+   * `apply` is gone; use the new `#*` and `#**` syntax instead

+   * Literal `Inf`s and `NaN`s must now be capitalized like that
+
+   [ Other Breaking Changes ]
    * `apply` has been replaced with Python-style unpacking operators `#*` and
      `#**` (e.g., `(f #* args #** kwargs)`)

+   * Single-character "sharp macros" are now "tag macros", which can have
      longer names
-   * Periods are no longer allowed in keywords
+   * `xi` from `hy.extra.anaphoric` is now a tag macro `#%`
    * `eval` is now a function instead of a special form
-   * Added a form of string literal called "bracket strings" delimited by
-     `#[FOO[` and `]FOO]`, where `FOO` is customizable
+
+   [ New Features ]
    * The compiler now automatically promotes values to Hy model objects
      as necessary, so you can write ``(eval `(+ 1 ~n))`` instead of
      ``(eval `(+ 1 ~(HyInteger n)))``
-   * Literal `Inf`s and `NaN`s must now be capitalized like that
-   * Numeric literals can no longer begin with a comma or underscore
-   * `get` is available as a function
-   * new `comment` macro
-   * support EDN `#_` syntax to discard the next term
    * `return` has been implemented as a special form
+   * Added a form of string literal called "bracket strings" delimited by
+     `#[FOO[` and `]FOO]`, where `FOO` is customizable
+   * Added support for PEP 492 (`async` and `await`) with `fn/a`, `defn/a`,
+     `with/a`, and `for/a`
+   * Added a macro `comment`
+   * Added EDN `#_` syntax to discard the next term
    * `while` loops may now contain an `else` clause, like `for` loops
-   * `xi` from `hy.extra.anaphoric` is now the `#%` tag macro
    * `#%` works on any expression and has a new `&kwargs` parameter `%**`
-   * new `doc` macro and `#doc` tag macro
-   * support for PEP 492 with `fn/a`, `defn/a`, `with/a` and `for/a`
-   * remove `def`
-   * support for relative imports (PEP 328)

    [ Bug Fixes ]
+   * Relative imports (PEP 328) are now allowed
    * Numeric literals are no longer parsed as symbols when followed by a dot
      and a symbol
-   * Hy now respects the environment variable PYTHONDONTWRITEBYTECODE
+   * Hy now respects the environment variable `PYTHONDONTWRITEBYTECODE`
    * String literals should no longer be interpreted as special forms or macros
    * Tag macros (née sharp macros) whose names begin with `!` are no longer
      mistaken for shebang lines
    * Fixed a bug where REPL history wasn't saved if you quit the REPL with
      `(quit)` or `(exit)`
    * `exec` now works under Python 2
-   * No TypeError from multi-arity defn returning values evaluating to None

+   * Multiple expressions are now allowed in `try`
    * Fixed a crash when `macroexpand`ing a macro with a named import

      `None` in this case.

-   * Fixed a crash when HyTypeError was raised with objects that had no

+   * Fixed a crash when `HyTypeError` was raised with objects that had no
      source position
    * `assoc` now evaluates its arguments only once each
-   * `break` and `continue` now raise an error when given arguments
-     instead of silently ignoring them
-   * Multiple expressions are now allowed in the else clause of

    [ Misc. Improvements ]
    * `read`, `read_str`, and `eval` are exposed and documented as top-level
      functions in the `hy` module
