------------------------ RELEASE 1.3.2 ------------------------

Bugfix release. This fixes a few problems in 1.3.1

* Sound system won't initialize properly under linux: Fixed.

* Panda DLL names now all start with "libp3" or "libpanda"

* Normals reversed in heightfield tesselator: fixed.

------------------------ RELEASE 1.3.1 ------------------------

Bugfix release. This fixes a few problems in 1.3.0

* Sound system won't initialize properly under linux: Fixed.(Update: Not fixed)

* Panda not compatible with SElinux: mostly fixed, except fmod.

* Max exporter and importer broken: Fixed.

* Minor problem involving gsg handling in showbase: Fixed.

------------------------ RELEASE 1.3.0 ------------------------

This release contains several new features, and as such, it might be

buggy. However, we've been testing it internally for a couple weeks,

and it seems to be okay. It contains the following new features:

* Stencil buffers and stencil operations now supported.

* Sound API now supports DSP and better support for large MP3s.

* Video uses FFMPEG instead of DirectShow - no more codec issues.

* Heightfield terrain.

* Support for intra-frame animation interpolation.

* Use of 'import *' now only imports correct symbols.

* Various minor improvements to the particle system.

* Scene editor at least partially operational (alpha level)

* Removed most of the 65,536 vertex-per-mesh limits.

* Various low-level optimizations.

* Support for threaded model loads (only in CVS, not in distro).

* Support for 'model-cache-dir', which caches a BAM each time you load an EGG.

* OnscreenText/DirectLabel can contain embedded 3D models inside the text.

------------------------ RELEASE 1.2.3 ------------------------

The last release was a disaster:

* I failed to fix packpanda.

* I broke the tcl/tk stuff.

* I added ppythonw, and it wasn't reliable.

So basically, this release fixes packpanda and tcl/tk. It doesn't

fix ppythonw yet (I don't know what's wrong), but it does disable

it temporarily. It keeps the few things from 1.2.2 that were worth

keeping.

------------------------ RELEASE 1.2.2 ------------------------

This is a minor bugfix release.

* Adds 'ppythonw', a version of ppython that doesn't

open a console window.

* If you have a bad fmod DLL in your windows folder,

this version compensates.

* Fixes a small bug in the VRML-to-egg converter.

* Small stylistic improvements in some sample programs.

------------------------ RELEASE 1.2.1 ------------------------

This release is likely to be much more stable than its predecessors.

It contains many new features:

* lots of performance optimizations

* a preliminary OSX port

* new modes for animation blending

* easier partial-body animations

* more powerful shader-to-engine interface

* better support for rotating bodies in physics engine

* support for compressed model files

* multiple render targets (ie, glDrawBuffers)

* support for stereo rendering

* more complete API reference manual

* ability to control mipmaps explicitly

* better tools for debugging offscreen buffers

* new sample programs

* a number of packpanda repairs

------------------------ RELEASE 1.1.0 ------------------------

This is a BETA release. It's pretty reliable, but there are still a

few quirks here and there. Over the summer, Panda3D was overhauled

top to bottom. The new code is dramatically improved, but it needs a

little bit of testing. The new features are:

* Much faster rendering of high-poly models.

* Dramatically improved vertex and pixel shader support.

* New demo programs using shaders and render-to-texture.

* Play movies by using an AVI as a texture (windows only).

* Python scripting uses much faster python to C++ interface.

* Support for procedurally-created geometry (eg, fractals, etc).

* Cleaner, simpler internal data structures.

* Comes with Python 2.4 support built-in.

* A lot more.

The new demo programs are:
