OGRE 1.0.6 [Azathoth] Released!

It's time for another maintenance release for those of you using the
stable 1.0.x branch of OGRE. Full details of bugfixes and non-interface
breaking changes included in this release are available in the full
text of this post; other highlights include support for Visual C++ 2005
and Softimage|XSI v5.0.

You can find the releases as usual in the downloads section – please
note that if you're using the Windows source release then you will also
need to update your dependencies; we provide 4 dependencies downloads
with this release, one for each of VC6, VC7.0, VC7.1 and VC8.0. You'll
also find 2 new prebuilt tools for Windows in this release from the
Addons projects, namely the Particle Editor and the CEGui Mesh Viewer.

Changes since v1.0.5:

Visual C++
2005 now supported, use Ogre_vc8.sln
XSI Exporter
- XSI v5 now supported (in addition to v4.0 and 4.2)
- Material exporter now picks up custom texture
  transforms correctly
- Fix for using multiple clusters with envelopes (bone
  assignment groups) spanning them.
- Don't export empty submeshes (caused by starting with
  polys which are later all reallocated to clusters)
D3D9 fixes:
- Render window writeContentsToFile method speeded up +
  some bugfixes
- Avoid a memory leak when GPU programs fail to load
- Fix potential surface leak when destroying a secondary
  window but not the device
GL fixes:
- Don't change GL context while creating a new render
  window if current context is available
- Share lists between render window GL contexts
- Fixed incorrect loaded state when creating a manual
  texture in GL
- Fixed many gcc warnings on GL atifs compiler
- Type correction for external / parent handles in GLX
  platform & doc corrections
D3D7 fixes:
- Fixed Dx7 device lost problems, switching from
  fullscreen to windowed and back now works in Dx7 too.
- Fix oblique projection on D3D7 (fix bad clipping on
  render to texture demo)
Mesh / Entity
fixes:
- XML format DTD
- Mesh::getSubMesh now safely checks for an index out of
  bounds condition.
- Unload mesh should clear bone assignments and removes
  reference to skeleton
- Added method to access manual levels of detail for the
  entity. Allow user more control to the lod level (e.g. change material,
  attach objects).
Hardware
vertex buffer pool fixes:
- TempBlendedBufferInfo destructor needs to make sure
  allocated buffer copies have been released – this bug showed up when
  entities using software skinned skeletal animation were removed from
  the scenemanager during rendering prior to frame ended finishing
- Buffer manager must make sure that no buffer copies or
  free temp vertex buffers exist that are associated with a vertex buffer
  that is being deleted
Logging
changes:
- Silently tolerate not having any log files to write to,
  so people can run logless if they really want.
- Allow suppression of file output on Log to allow a
  LogListener-only setup
Shader fixes:
- Correct number of constants supported by ps_1_x
- Fix ps_2_x detection; report as ps_2_a/b but assembler
  syntax is still called ps_2_x
- Fixed
  memory/resource leak of high-level GPU program in the case qhere the
  high-level portion is loaded, but the low-level GPU program itself
  never loaded
Shadow fixes:
- Fix missing shadow volume extrude program parameters
  when shadow volume materials initialised somewhere else
- Resolve an issue when find shadow casters for light,
  and the light is attached to scene node. Should use derived light
  position/direction to query for shadow casters
Material fixes:

Ensure that custom texture transforms are serialised /
deserialised into .material scripts
When
material recompile required, need to unload whole content of material,
avoid leak because some TUS animation/effect controllers maybe created.
Fix cloning problems when using the ACT_TIME auto
parameter

Texture fixes:
- TextureManager loadImage/loadRawData
  should be create texture as manual texture without loader, in fact the
  texture can't auto reload again.
- Enable/disable 32-bit textures now work properly even
  if no texture exists, and only reloads the loaded and reloadable
  textures.
- You
  can now access the original dimensions of the texture image even if the
  final texture dimensions (due to hardware requirements) are different
Dependencies
updated

Freetype is now v2.1.1.0

DevIL is now 1.6.7

zlib is now 1.2.3

zzliplib is now 0.13.44 (this fixes a memory leak when
reloading resources from a zip file)

CEGui remains at 0.3.x since 0.4.x requires potential
changes to custom looks, users are free to upgrade themselves (but will
need the source release, not the SDK)

Particle
systems:

Delay loading of image on ColourImage particle affector
to avoid startup overhead, and deal with more formats instead of
assuming pixel format

Should check for duplicates before creating/adding new
particle system templates, otherwise leakage

Disable gcc version script which causes problems in gcc
v4.x
Add the ability to raise and listen in on
RenderSystem-specific
events (allows people to listen in on device lost / restore if they
choose to)
Fix comparison bug in HardwarePixelBuffer::blit which would
cause it to scale unnecessarily
Solve crash when ray scene query is done without landscape
loaded in TerrainSceneManager
Open data streams one at a time while parsing scripts to
avoid opening a lot of disk files simultaneously that may exceed file
handle limits
Allow archives to be unloaded
Fixed destroying track which maybe absent, just ignore it
when this situation happens
Fix merging of CEGui flags in Linux build
Don't allow double-load of plugins
Gracefully deal with invalid requests to use the same
SceneNode name more than once
RenderTarget::writeContentsToTimestampedFile now writes out
the date/time in correct human readable format
Fix for "unknown property."scale" in $Biped_Object" error
in 3DSMax exporter
OverlayElement parent overlay initialisation fixed
Several documentation corrections
