 --------------------------
 Changes in 1.9 (not yet released)
 
+- Fixed issue with wrongly enabled Z-writing for transparent shader materials. Thanks Hendu for this fix.
 - Allow more control over particle behavior. This also changed the default behavior.
 - ISceneNodeAnimators can now be disabled and paused.
 - Maya camera no longer get's stuck in "rotating" state when a mouse-up event is lost (thx @ JLouisB for reporting).

 - CGUICheckBox no longer gives up focus on EMIE_LMOUSE_LEFT_UP (thx @Demre and @REDDemon for reporting)
 - Bugfix: IGUIElement::addChild now prevents setting an element as it's own child.
 - GUI editor improvements (prevent crash, improve UI)
-- Add IrrlichtDevice::setWindowSize. 
+- Add IrrlichtDevice::setWindowSize.
 - Bugfix: getFont for xml-fonts now also works for fonts inside archives (thx @Neirdan for bugreport)
-- Added function irr::core::mergeFilename 
+- Added function irr::core::mergeFilename
 - Add ISceneNodeAnimator::setStartTime/getStartTime to allow resetting movement animators.
 - Improve speed for finalizing skinned meshes (removal of unnecessary frames after loading) (thx @ichtyander for the testmodel)
 - Collada loader now instantiates camera nodes which had been ignore so far (thx @NemoStein for the test .dae)
 - line2d::intersectWith has a new parameter to allow ignoring intersections with coincident lines
-- vector2d::equals now has an tolerance parameter for passing the epsilon (like vector3d had). Note that this changes the default 
+- vector2d::equals now has an tolerance parameter for passing the epsilon (like vector3d had). Note that this changes the default
   behavior of vector2d::equals as well as functions using it like the operators for ==, !=, <, >, <=, >= when using vector2d with f64
   as the tolerance is increased in that case (for f32 and integer values it shouldn't make any difference).
 - Material renderers which offers blending feature (eg. EMT_TRANSPARENT_ALPHA_CHANNEL, EMT_ONETEXTURE_BLEND etc.) require SMaterial::BlendOperation set to other value than EBO_NONE.
