• Platform::Sdl2Application is now used everywhere (documentation, tutorials, examples) by default, replacing Platform::GlutApplication. The GLUT application is still available, though. See mosra/magnum#39.

• Convenience hasNormals(), hasTextureCoords2D() functions to Trade::MeshData2D and Trade::MeshData3D
• OpenGL ES 3.0 build now shares list of vendor extensions with OpenGL ES 2.0 build (i.e. only those extensions that aren't part of ES 3.0 are present in Extensions)

Changes

• Preferring absolute includes instead of relative (see mosra/magnum#36)
• The magnum-distancefield utility is now named Distance Field conversion utility for consistency with other command-line utilities

• Query::result<bool>() returns true if value is nonzero (was returning true only for value of 1 previously)
• All functions in MeshTools namespace are now returning either Corrade::Containers::Array or std::unique_ptr instead of naked pointers to avoid accidental out-of-bounds access and memory leaks
• All functions in Text namespace are now returning std::unique_ptr instead of naked pointers to avoid accidental memory leaks
• Implementation of Platform::*Application::viewportEvent() is not required anymore, because in many cases the application doesn't need to react to window resize events at all

• All deprecated functions and types are now emitting compiler warnings to encourage updating the code
• Various documentation and example updates and improvements

Bug fixes

• Fixed building issues with CMake-generated XCode project on OS X. See also mosra/magnum#37.
• Proper and failsafe OpenGL 3 context creation on OS X (3.0 is implemented only as core context, thus requesting 2.1 won't expose newer features). See also mosra/magnum#26, mosra/magnum#35 and mosra/magnum#43.
• Fixed compilation issues with Clang and libc++
• Fixed various compilation issues under MSVC (and worked around an insane amount of compiler bugs)

Deprecated APIs

Potential compatibility breakages, removed APIs

• Removed SceneGraph::*Transformation::move() from 2D transformation classes. It was originally meant for modifying draw order, but as the draw order is managed by SceneGraph::DrawableGroup class and not by parent object, this function is essentially useless.

Documentation

• Various documentation updates and fixes (see mosra/magnum#28)

Internal changes

• Added thorough tests for all core OpenGL functionality to make refactoring easier
• Various internal optimizations and cleanup to make maintenance easier
• Using Jenkins Continuous Integration to maintain compilable and bug-free state of the project more easily. Currently GCC 4.8, 4.7, 4.6, 4.5, 4.4, Clang 3.3, Clang 3.3 with libc++, Emscripten, x86-32/x86-64 Native Client and MinGW32 compilers are tested with both shared and static libraries. Separately testing builds with deprecated features enabled and disabled. Also explicitly testing desktop OpenGL, OpenGL ES 2.0, desktop OpenGL ES 2.0 emulation, OpenGL ES 3.0 and desktop OpenGL ES 3.0 emulation.
• All files from src/ directory were moved to src/Magnum, external/ directory was moved to src/MagnumExternal (required to make inter-project includes absolute, as mentioned above)

Dependency changes

• Removed GLEW dependency in favor of built-in glLoadGen, resulting in greatly reduced compilation time and less compatibility issues. The base library thus now depends only on Corrade and OpenGL libraries. See mosra/magnum#11, mosra/magnum#16, mosra/magnum#21, mosra/magnum#22, mosra/magnum#23.

New features

• Initial Emscripten (HTML5/WebGL) port. See Platform::Sdl2Application for detailed porting information. The examples page has now links to online Emscripten demos, see also base-emscripten branch in Magnum Bootstrap.

Note that template aliases are not present in GCC 4.6 builds.
• Limit queries for all OpenGL objects, the information is now printed also by magnum-info utility.
• Context::isExtensionSupported() is now able to query extension availability on particular GLSL version
• Using std::unique_ptr and C++1y std::optional for resources returned from Trade::AbstractImporter for better usability and to avoid accidental memory leaks

• Detailed collision queries and new InvertedSphere shape in Shapes library
• Texture support in Shaders::Flat
• Mouse button queries in Platform::*Application::MouseMoveEvent

• Extension support queries depend on selected GLSL version (see mosra/magnum-examples#3)

Deprecated APIs
