   - scale related functions moved from `Matrix4` to `Matrix3`: porting `.hasScale()` →  `.linear().hasScale()`
   - similarly `transformDirectionAffine` is now done by extracting the linear part via `linear()` and using `operator*` of `Matrix3`, that has now improved performance.
 
+* `TextureUnit` no longer caches any `Texture` state. All texture related calls now forward to the assigned Texture. If there is no Texture assigned, calls to e.g. `TextureUnitState::setNumMipmaps` have no effect.

 * Textures must not be declared in an Ogre Script *and* be manually created. Ogre now immediately creates all Textures declared in scripts (in unloaded state). Previously it was possible to declare a texture name in the Material and create a manual texture before the material was fully loaded. This is not possible any more.
 If you were relying on the old behaviour, you now must explicitly set you manual texture via `->getTextureUnitState(..)->setTexture(manualTex)`.

 * Reduced Memory consumption of core classes
   - by reducing padding and using bitfields for boolean flags, the memory consumption of e.g. `Pass` could be reduced by 11%.

 * Generic Image codecs (STB Image, FreeImage) are now plugins. For distribution you should use compressed textures (e.g. DDS) with precomputed mipmaps. Having the generic codecs as plugins allows you to easily disable them. Editing software on the other hand can now easily swap in a custom implementation (like QImage).
 
+* `Image::flipAroundX/Y` now operate in-place instead of allocating temporary memory.

 * Mesh: does not use CPU shadow buffers by default any more. If you were relying on fast read access, you will have to explicitly request shadow buffers. Everybody else just saves memory now.
 
 * `PF_DEPTH` now correctly works with `TU_RENDERTARGET`. This will create a depth-only FBO and give you the raw depth values, without needing any special shaders.

 ## Overlay
 Overlay scripts now support the standard ogrescript syntax and the `template` keyword is now optional.
