This is a major release, with several big new features. As such,
it is likely to contain bugs.

• True threading support now enabled in the default build
• Pipelined rendering: app, cull, and draw can run in parallel, each in their own thread
• Web plugin is more robust, and better supports Safari and Chrome
• Plugin runs properly when the username contains non-ASCII characters on Windows
• Added appRunner.p3dFilename and appRunner.p3dUrl to provide p3d location
• Multifiles (and p3d files) now make a distinction between binary and text files
• OccluderNode added for explicit occlusion culling
• Ambient occlusion generation for terrain
• Fixed bug where Windows installer wipes %PATH% when it’s too long
• Added fog support to the shader generator
• Added normal_gloss texture mode
• Added a custom color option to the cartoon filter
• Support for texture arrays in shaders
• Better shader support in pandadx9
• Fix some issues with cube map buffers
• Can be compiled to use double-precision floats throughout, instead of the default of single-precision floats. (Graphics drivers still use single-precision floats, of course.)
• Can be compiled with the optional Eigen library to provide SSE2 support
• Can be compiled with SpeedTree support
• Can be compiled on MSVS2010, and/or Win64. (These builds not provided by default.)
• Support for the Bullet physics engine
• Support for the libRocket GUI library
• Support for stereo/multiview textures
• Substantial performance improvements to movie textures
• TGA files with alpha channel now load correctly
• New “Ramdisk” mount type available for the VFS
• The VFS is now writable for ramdisk files and true on-disk files
• pdeploy -i generates a custom icon for the installed game
• wx and tk work better on OSX
• Panda windows can be embedded within wxPython windows on all platforms (including OSX) with the new WxPandaWindow class
• Added base.pixel2d for pixel-based 2-D coordinates
• Python-based swizzling of Panda vectors, e.g. vec2.xyxy
• Python programmers can now optionally use the original unmangled C++ name for methods and classes, e.g. model.set_pos(LPoint3f(1, 2, 3)).
• Command-line filename globbing now supported on Win32, e.g. egg-texture-cards *.png
• DirectGui works with nonstandard coordinate-system in effect
• Egg loader handles double-sided polygons a little differently by default now, for better render performance but more memory usage (use “egg-emulate-bface 0” to restore the old behavior if needed).
