This beta is currently for the Windows platform only and includes standard,
SSE2, and 64-bit binaries.

---------------------------------------------------------------------------
The following features are not supported but will be added prior to release
---------------------------------------------------------------------------
o Animation.
o Radiosity.
o Dispersion.
o Mosaic preview.
o Light and vista buffers. These may replaced with a more efficient system.
o Ability to choose block size allocated to threads.
o Resume render (a.k.a. 'continue').
o Windows rerun dialog and statistics.
o Redirecting text message output to files.
Known issues which will be fixed
--------------------------------
o There is an issue with media and transparency. See
<42769324$1@news.povray.org>.
o The windows editor does not always detect new files as type 'povray'.
o Text layout of windows message page not yet finished (e.g. no wrapping,
early wrapping).
o There are memory leaks, and memory tracking is not yet complete.
o In many cases speed is not as good as 3.6.
o Photon support is not yet completed.
o There are some differences in the way gamma correction works.
o Anti-aliasing method 2 currently takes more samples than in version 3.6
and earlier.

Intentional changes for POV-Ray 3.7
-----------------------------------
The version directive and command-line setting no longer provide compati-
bility with most rendering bugs in versions prior to POV-Ray 3.5. However,
compatibility with the scene language is provided for scenes as old as POV-
Ray 1.0 just as in all previous versions of POV-Ray. Nevertheless, we
strongly recommend you update scenes at least to POV-Ray 3.5 syntax if you
plan to use them in future versions of POV-Ray.
This version uses multi-threaded rendering by default. The ability to render
in more than one thread is primarily of use to those users who have SMP
machines (i.e. more than one CPU). There have been reports of benefits for
users of hyperthreading systems, particularly with higher thread counts (e.g.
16 threads).
You can render in only one thread by using the '/THREADS 1' switch in the
Windows version. Note that parsing and photon building will only use one
thread no matter how many are specified. However photon scenes will benefit
from multiple threads once photon building has completed.
