RELEASE NOTES for Falcon

                              Chimera Release

                                  0.9.6.6
  
  "Chimera" version is an intermediate version that bridges Eagle series
with the next series, in which we should put in the final compiler/module
assets.

  This is the last bugfix release in the Chimera version, and closes the
series of 0.9.6.6 releases.

  IMPORANT DISCLAIMER: starting from this version, we're introducing the
mersenne twister algorithm for random number generation. The permission
to use it has been granted by one of the authors, as described in the
README.mersenne file.


New Features
============

  - The hash module has been added to feathers; it provides a set of popular
    hashing facilities as MD5, SHA256, HMAC and many more.
  - Message oriented programming has now an "event model" message generation,
    which is added to VMSlot class.
  - Added method Dictionary.dop (default operation) -- a facility that makes
    easier to create maps of complex items (i.e. maps of lists) with a one-liner.
  - Added methods Dictionary.do and Array.concat
  - Added Base64 class.
  - New epoch() function returning exactly the seconds since UNIX epoch.

Critical bug fixes
==================

  - toString() crashed when called without a parameter.
  - Failing to init the frame in new VMContexts would have caused random
    crashes depending on linkage or memory conditions.
  - Immediate array unpack was causing an assert in case of wrong sizes.
  - passvp() was failing if calling function had local vars
  
Usage tips
==========

   Although the new Garbage Collector is relatively efficient in determining
the actual needs of applications and in reclaiming unused memory, the standard
detection algorithms are still a bit naive.

  If your application is memory-intensive, be sure to read the Core Module
Documentation about the new GC object, which provides four default collection
strategies and also allows you to implement your own. A finely tuned GC 
strategy can boost the performance of your application and reduce its memory 
footprint.

  Meanwhile we'll continue to work towards finding collection strategies 
applicable to the most common usage patterns and you're invited to provide 
your own, should this aspect of Falcon be critical to your application.
