v0.5.0

Fixed

• Return values are now properly declared, captured, and returned as needed.
• bin/wrapture now checks the version number of specs it processes.

Removed

• Ruby 2.3 is no longer supported.

v0.4.2

Fixed

• Functions that return function pointers now cast the return correctly instead
  of containing non-valid code
  (issue #76).
• Return value types are now valid types when they are given using a special
  keyword in the spec, such as equivalent-struct-pointer. The types are now
  resolved based on the keyword if one is used
  (issue #77).
• The list Wrapture::KEYWORDS now contains the value in
  Wrapture::SELF_REFERENCE_KEYWORD.
• throw-exception actions with no parameters for the constructor no longer
  cause an error
  (issue #78).
• Return values are correctly switched to the equivalent struct in
  constructors instead of using return_val, which was not actually set
  (issue #84).
