Changes from Hy 0.9.8

  [ Syntax Fixes ]

    * Macros are now module-specific, and must be required when used. (KH)
    * Added a few more string escapes to the compiler (Thomas Ballinger)
    * Keywords are pseudo-callable again, to get the value out of a dict. (PT)
    * Empty expression is now the same as an empty vector. (Guillermo Vaya)

  [ Language Changes ]

    * HyDicts (quoted dicts or internal HST repr) are now lists
      that compiled down to dicts by the Compiler later on. (ND)
    * Macros can be constants as well. (KH)
    * Add eval-when-compile and eval-and-compile (KH)
    * Add break and continue to Hy (Morten Linderud)
    * Core language libraries added. As example, I've included `take` and
      `drop` in this release. More to come (PT)
    * Importing a broken module's behavior now matches Python's more
      closely. (Morten Linderud)

  [ Misc. Fixes ]

    * Ensure compiler errors are always "user friendly" (JD)
    * Hy REPL quitter repr adjusted to match Hy syntax (Morten Linderud)
    * Windows will no longer break due to missing readline (Ralph Moritz)


Changes from Hy 0.9.7

  [ Syntax Fixes ]

      expand things in quotes.
    * kwapply now works with symbols as well as raw dicts. (ND)
    * Try / Except will now return properly again. (PT)
    * Bare-names sprinked around the AST won't show up anymore (ND)

  [ Language Changes ]

    * (fn) and (lambda) have been merged (ND)
    * New (defclass) builtin for class definitions (JD)
    * Add unquote-splicing (ND)

  [ Errata ]

      actually ND. My bad.

Changes from Hy 0.9.6

  [ Syntax Fixes ]

    * UTF-8 encoded hy symbols are now hy_... rather than __hy_..., it's
      silly to prefex them as such. (PT)
    * `j' is no longer always intepreted as a complex number; we use it much
      more as a symbol. (ND)
    * (decorate-with) has been moved to (with-decorate) (JD)
    * New (unless) macro (JD)
    * New (when) macro (JD)

    * new (global) builtin (@eal)
    * new lambda-list syntax for function defs, for var-arity, kwargs. (JK)

  [ Language Changes ]

    * *HUGE* rewrite of the compiler. Massive thanks go to olasd
      and jd for making this happen. This solves just an insane number
      of bugs. (ND, PT, JD)
    * Eval no longer sucks with statements (ND)
    * New magic binary flags / mis fixes with the hy intepreter
      (WKG + @eigenhombre)


Changes from Hy 0.9.5

  [ Syntax Fixes ]

    * .pyc generation routines now work on Python 3. (Vladimir Gorbunov)
    * Allow empty (do) forms (JD)
    * The `else' form is now supported in `try' statements. (JD)
    * Allow `(raise)', which, like Python, will re-raise
      the last Exception. (JD)
    * Strings, bools, symbols are now valid top-level entries. (Konrad Hinsen)
    * UTF-8 strings will no longer get punycode encoded. (ND)
    * bare (yield) is now valid. (PT)
    * (try) now supports the (finally) form. (JD)

    * (foreach) now supports the (else) form. (JD)

  [ Language Changes ]

    =============== WARNING: WARNING: READ ME: READ ME: ===================
    From here on out, we will only support "future division" as part of hy.
    This is actually quite a pain for us, but it's going to be quite an
    amazing feautre.

    This also normalizes behavior from Py 2 --> Py 3.

    Thank you so much, Konrad Hinsen.
    =======================================================================

    * (pass) has been removed from the language; it's a wart that comes from
      a need to create valid Python syntax without breaking the whitespace
      bits. (JD)
    * We've moved to a new import style, (import-from) and (import-as) will
      be removed before 1.0. (GN)
    * Prototypes for quoted forms (PT)
    * Prototypes for eval (PT)
    * Enhance tracebacks from language breakage coming from the compiler (JD)
    * The REPL no longer bails out if the internals break (Konrad Hinsen)
    * We now support float and complex numbers. (Konrad Hinsen)
    * Keywords (such as :foo) are now valid and loved. (GN)

Changes from Hy 0.9.4

  [ Syntax Fixes ]

    * Statements in the `fn' path early will not return anymore. (PT)

    * `catch' now accepts a new format: (JD)

        (catch [e Exception] BODY)
        (catch [e [Exception1 Exception2]] BODY)
