Hello,
after some months and 605 source code commits compared to the previous
release, today it's finally time to release version 2.5.1 of the realXtend
Tundra SDK.

Like before, the Windows & OS X binary downloads are at
http://code.google.com/p/realxtend-naali/downloads/list

A first time for the Tundra core releases, we now have also 64-bit Windows
builds. This should help with running against the 2GB process memory limit
in 32-bit builds.

The major changes, new features and fixes include (an overwhelming
majority of these have been contributed by Admino Technologies):

- Update to Qt 4.8.5 on Windows and OS X.
- Update to Ogre 1.9 RC1.
- Update to a new version of MathGeoLib with several new functions and
bugfixes.
- Configurable texture budget: when exceeded or near exceeded, textures
will be loaded in reduced resolution.
- Ogre instancing support in the Mesh component. Automatic generation of
instanced versions of the SuperShaders.
- Threaded HttpAssetProvider cache write to improve performance and
responsiveness when loading a scene with a "cold" cache.
- Improved build and installer scripts on Windows, including support for
64-bit targets. Installer detects and optionally removes old Tundra
installation.
- Improved Linux build script. Contributed by Peter C.
- Possibility to build only Debug or Release dependencies instead of both
to reduce the dependencies build time.
- Cleaned up startup configuration file syntax: use the same commands as
command line startup parameters. Allow configuration files to include
other configuration files.
- All startup parameters unified to lowerCamelCase format for better
readability. Old format also retained for now.
- Possibility to access scene components without the EC_ prefix from
script; .txml files saved without the EC_ prefix.
- Possibility to access entity's components in lowerCamelCase from script
for better readability.
- Support for grouping entities in the Scene Structure window.
- Show attributes optionally in the Scene Structure window.
- Live-update attribute metadata in the EC-editor if changed during runtime.
- Split less used or deprecated modules to the TundraAddons repository.
- Add version information to the Tundra executables and libraries on Windows.
- Distance along the ray added to RayCastResult.
- RaycastAll() functions in OgreWorld for returning all hit objects along
a ray.
- PhysicsConstraint component.
- Separate machine-readable ID's for component attributes in addition to
the human-readable attribute names. This allow changing the human-readable
name without breaking scene files.
- Help text is shown if starting Tundra without a scene file.
- Improved Profiler display. kNet network statistics shown in its own
Profiler tab by default.
- Bug fixes to allow creating components unparented (without a scene or
entity). When serializing a scene description on import, use this feature
to prevent changing the actual scene yet.
- Transform gizmo bugfix: allow unlimited drag to the negative axis
direction.
- Fix loading of Ogg Vorbis sounds sometimes producing garbage audio.
- API cleanup; more getter functions modified to concise form without the
Get-prefix. Old functions retained, but marked deprecated.

Have fun!


- Lasse
