    specifying each and every one (see [mosra/magnum#73](https://github.com/mosra/magnum/issues/73)).
-   Ability to control static build of plugins separately using
    `BUILD_PLUGINS_STATIC`.
-   Displaying all header files, plugin metadata files and resource files in
    project view to make use of some IDEs less painful (such as QtCreator).
-   Gentoo ebuild (see [mosra/magnum#69](https://github.com/mosra/magnum/issues/69),
    [mosra/magnum#83](https://github.com/mosra/magnum/issues/83)).

@subsection changelog-2014-06-deprecated Deprecated APIs

-   @cpp Mesh::setVertexCount() @ce and @cpp Mesh::setIndexCount() @ce had
    nonintuitive behavior in some corner cases and are deprecated, use general
    @cpp Mesh::setCount() @ce function instead
-   @cpp MeshView::setVertexRange() @ce and four-/two-argument
    @cpp MeshView::setIndexRange() @ce are deprecated for similar reason as
    above, use @cpp MeshView::setCount() @ce, @cpp MeshView::setBaseVertex() @ce
    and three-/one-argument @cpp MeshView::setIndexRange() @ce instead

-   @ref MeshTools::compressIndices() and @ref MeshTools::interleave()
    which filled @cpp Mesh @ce and @cpp Buffer @ce directly are deprecated as
    they had undesired side-effects in some cases, use the data-returning
    versions instead and then configure mesh and buffer manually
-   @ref MeshTools::combineIndexedArrays() taking @ref std::tuple is
    deprecated, use version taking @ref std::pair instead
-   @ref MeshTools::removeDuplicates() taking also list of indices is
    deprecated, use the function in conjunction with @ref MeshTools::duplicate().
    See function documentation for more information.
-   Parameter-less @cpp Mesh::draw() @ce and @cpp MeshView::draw() @ce are
    deprecated, use versions with explicit shader parameter instead
-   Deprecated implicit conversion of @ref Resource "Resource<T, U>" to
    @cpp U& @ce, as it is not safe. Use explicit dereference operator instead.

    functions of particular shaders instead (e.g.
    @cpp Shaders::Phong::setDiffuseTexture() @ce)

    @cpp Context::Flag::RobustAccess @ce which reflects OpenGL naming better
    instead

        and @cpp Buffer::setSubData() @ce, use overloads taking
        @cpp Containers::ArrayReference @ce instead
    -   Removed deprecated `Magnum/ImageFormat.h` header and
        @cpp ImageFormat @ce/@cpp ImageType @ce enums, use `Magnum/ColorFormat.h`
        header and @cpp ColorFormat @ce/@cpp ColorType @ce enums instead

        enum instead
    -   @cpp Platform::Sdl2Application::Configuration::Flag @ce enum and related
        functions were replaced with WindowFlag, as the name would now conflict
        with context flags

@subsection changelog-2014-06-internal Internal changes

-   Removed last remaining bits of global state, everything is now stored
    per-context.

@subsection changelog-2014-01-new New features

-   MSVC 2013 support in `compatibility` branch
-   Dependency-less plugins from Magnum Plugins repository are now part of
    Magnum to make their usage easier, in particular the @ref Text::MagnumFont "MagnumFont",
    @ref Text::MagnumFontConverter "MagnumFontConverter",
    @ref Trade::TgaImporter "TgaImporter", @ref Trade::TgaImageConverter "TgaImageConverter"
    and @ref Audio::WavImporter "WavAudioImporter" plugins.
-   Documented @ref opengl-support "state of OpenGL support",
    @ref opengl-mapping "mapping between OpenGL and Magnum API",
    @ref plugins "general plugin usage" and added
    @ref troubleshooting "troubleshooting page" for most common building and
    rendering issues
-   Support for horizontal and vertical text alignment and multi-line text in
    @ref Text::Renderer (line wrapping is still left up to the user)
-   New @ref magnum-fontconverter utility for converting between font formats
    (e.g. creating distance-field raster font from TTF font). Enable it with
    `WITH_FONTCONVERTER` CMake option (currently Linux only), see
    `magnum-fontconverter --help` for more information.
-   Support for OpenGL object labels, debug message insertion and retrieval
    (@gl_extension{KHR,debug}, @gl_extension{EXT,debug_label} and @gl_extension{EXT,debug_marker}
    extensions) (see [mosra/magnum#42](https://github.com/mosra/magnum/issues/42))
-   @ref Platform::BasicScreenedApplication "Platform::ScreenedApplication"
    class allowing the users to easily use multiple independent screens in the
    application.
-   New 1D, 2D and 3D @ref Math::Range class
-   Added @cpp red() @ce, @cpp green() @ce, @cpp blue() @ce, @cpp cyan() @ce,
    @cpp magenta() @ce and @cpp yellow() @ce convenience functions to @ref Color3
    and @ref Color4 classes
-   Convenience @ref Color3ub and @ref Color4ub typedefs
-   New @cpp version() @ce utility functions for converting @cpp Version @ce
    enum value to major/minor version number and back
-   Added @cpp release() @ce function to @ref Image and @ref Trade::ImageData
    for releasing ownership of the data, similar to @ref std::unique_ptr::release()
    (see [mosra/magnum#29](https://github.com/mosra/magnum/issues/29))
-   @cpp *Image::dataSize() @ce function for computing size of buffer required
    to store image of given size
-   Disallowing conversion of rvalue @ref Image and @ref Trade::ImageData
    to ImageReference as it would result in access to deleted memory (GCC
    4.8.1/Clang only)
-   No-op fallback for @cpp *Texture::setMaxAnisotropy() @ce in case
    @gl_extension{EXT,texture_filter_anisotropic extension} is not supported
-   Added @cpp round() @ce, @cpp floor() @ce and @cpp ceil() @ce scalar/vector
    functions to @ref Math namespace
-   @ref Math::minmax() and @ref Math::Vector2::minmax() functions
-   Modulo operations for integral @ref Math::Vector classes
-   Ability to request context version in all windowed
    @ref Platform::Sdl2Application "Platform::*Application" classes
-   Mouse wheel support in @cpp Platform::NaClApplication::MouseEvent @ce
-   No-op `Platform::GlutApplication::keyReleaseEvent()` and
    @cpp Platform::NaClApplication::Configuration::setTitle() @ce functions to
    preserve source compatibility with other application classes.
-   @ref SceneGraph::Drawable::drawables() function as a non-ambiguous
    alternative to @cpp group() @ce
-   Ability to specify background color color in @ref Shaders::Vector,
    allowing it to use without blending enabled (fully transparent black was
    used previously)
-   New @ref Shaders::Generic class with common definitions, so you can
    configure mesh for the generic shader and render it with any other
    compatible shader
-   Convenience @cpp hasNormals() @ce, @cpp hasTextureCoords2D() @ce functions to
    @ref Trade::MeshData2D and @ref 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
    @cpp Extensions @ce)
-   All classes in documentation are now shown with corresponding @cpp #include @ce
    path

@subsection changelog-2014-01-changes Changes

-   Preferring absolute includes instead of relative (see [mosra/magnum#36](https://github.com/mosra/magnum/issues/36))
-   The `magnum-distancefield` utility is now named @ref magnum-distancefieldconverter
    for consistency with other command-line utilities
-   @cpp ImageReference @ce class now stores const data pointer instead of
    mutable one, modifying the data through the class interface isn't valid use
    case anyway
-   Added default template parameter to @cpp Buffer::data() @ce and made
    @ref Image::data() "*Image::data()" templated to have them consistent.
    Note that this is source-compatible change.
-   @cpp Query::result<bool>() @ce returns @cpp true @ce if value is nonzero
    (was returning @cpp true @ce only for value of 1 previously)
-   All functions in @ref MeshTools namespace are now returning either
    @ref Corrade::Containers::Array or @ref std::unique_ptr instead of naked
    pointers to avoid accidental out-of-bounds access and memory leaks
-   All functions in @ref Text namespace are now returning @ref std::unique_ptr
    instead of naked pointers to avoid accidental memory leaks
-   Implementation of @ref Platform::Sdl2Application::viewportEvent() "Platform::*Application::viewportEvent()"
    is not required anymore, because in many cases the application doesn't need
    to react to window resize events at all
-   Textured @ref Shaders::Flat now multiplies texture with the specified
    color instead of ignoring it. See also [mosra/magnum#34](https://github.com/mosra/magnum/issues/34)
-   All deprecated functions and types are now emitting compiler warnings to
    encourage updating the code
-   Various documentation and example updates and improvements

@subsection changelog-2014-01-bugfixes Bug fixes

-   Fixed @cpp CubeMapTextureArray::image() @ce function (more precisely it
    wasn't working at all). See also [mosra/magnum#31](https://github.com/mosra/magnum/issues/31).
-   Fixed wrong assertion in @cpp Texture::setWrapping() @ce for rectangle
    textures
-   Fixed wrong assertion in @cpp AbstractImage::pixelSize() @ce when computing
    size of separate depth and stencil formats
-   @cpp Mesh::addVertexBuffer() @ce now properly computes offsets for matrix
    attributes
-   Taking index buffer offset into account in @cpp MeshView @ce class
-   Fixed various issues with textured @ref Shaders::Flat shader (actually
    the textured version was not working at all)
-   Various OS X-related fixes in @ref Shaders library. See also
    [mosra/magnum#27](https://github.com/mosra/magnum/issues/27).
-   Fixed building issues when both SDL1 and SDL2 is installed on OS X. See
    also [mosra/magnum#25](https://github.com/mosra/magnum/issues/25),
    [mosra/magnum#38](https://github.com/mosra/magnum/pull/38).
-   Fixed building issues with CMake-generated XCode project on OS X. See also
    [mosra/magnum#37](https://github.com/mosra/magnum/issues/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](https://github.com/mosra/magnum/issues/26),
    [mosra/magnum#35](https://github.com/mosra/magnum/issues/35) and
    [mosra/magnum#43](https://github.com/mosra/magnum/pull/43).
-   Fixed compilation issues with Clang and libc++
-   Fixed various compilation issues under MSVC (and worked around an insane
    amount of compiler bugs)

@subsection changelog-2014-01-deprecated Deprecated APIs

-   @cpp Buffer::Usage @ce enum is deprecated to reduce header dependencies,
    use global @cpp BufferUsage @ce enum instead
-   @cpp Mesh::Primitive @ce enum is deprecated to reduce header dependencies,
    use global @cpp MeshPrimitive @ce enum instead
-   @cpp Sampler::maxAnisotropy() @ce is deprecated to avoid naming conflict with
    @cpp *Texture::setMaxAnisotropy() @ce, use
    @cpp Sampler::maxMaxAnisotropy() @ce instead
-   @cpp Magnum::Geometry::Rectangle @ce class (and @cpp Rectangle* @ce typedefs)
    is deprecated, use more generic and feature-rich @ref Math::Range
    instead.
-   @cpp Platform::Sdl2Application::Configuration::setFlags() @ce function and
    related enum is deprecated to avoid naming conflict in the future, use @ref Platform::Sdl2Application::Configuration::setWindowFlags() instead
-   @cpp SceneGraph::Animable::group() @ce is deprecated, use non-ambiguous
    @ref SceneGraph::Animable::animables() instead
-   `Magnum/Shaders/magnumShadersResourceImport.hpp` header is deprecated in
    favor of less verbose `Magnum/Shaders/resourceImport.hpp`
-   @cpp Text::TextRenderer @ce class (and @cpp Text::TextRenderer2D @ce,
    @cpp Text::TextRenderer3D @ce typedefs) is deprecated, use less redundant
    name @ref Text::Renderer instead

@subsection changelog-2014-01-compatibility Potential compatibility breakages, removed APIs

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

@subsection changelog-2014-01-documentation Documentation

-   Various documentation updates and fixes (see
    [mosra/magnum#28](https://github.com/mosra/magnum/issues/28))

@subsection changelog-2014-01-internal 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)

@section changelog-2013-10 2013.10

Released 2013-10-30, tagged as
[v2013.10](https://github.com/mosra/magnum/releases/tag/v2013.10). See the
[release announcement](https://blog.magnum.graphics/announcements/october-2013-updates/)
for a high-level overview.

@subsection changelog-2013-10-dependencies 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](https://github.com/mosra/magnum/issues/11),

    and non-transforming square matrices in @ref Math namespace,
    @ref Matrix3x2 "MatrixNxN" and @ref Matrix2x2d "MatrixNxNd" typedefs for
    @cpp float @ce and @cpp double @ce non-transforming square matrices in root
    Magnum namespace. 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 @ref magnum-gl-info "magnum-info" utility.
-   @cpp Context::isExtensionSupported() @ce is now able to query extension
    availability on particular GLSL version
-   Using @ref std::unique_ptr and C++1y @ref std::optional for resources
    returned from @ref Trade::AbstractImporter for better usability and to
    avoid accidental memory leaks
-   New translation-only transformation in @ref SceneGraph supporting also
    purely integral coordinates, useful e.g. for UI or 2D platformers.
-   Detailed collision queries and new `InvertedSphere` shape in Shapes library
-   Texture support in @ref Shaders::Flat
-   Mouse button queries in @ref Platform::Sdl2Application::MouseMoveEvent "Platform::*Application::MouseMoveEvent"

@subsection changelog-2013-10-changes Changes

-   @cpp Buffer::setData() @ce and @cpp Buffer::setSubData() @ce are now
    accepting @cpp Containers::ArrayReference @ce for more convenient usage
-   @ref Platform::Sdl2Application::viewportEvent() "Platform::*Application::viewportEvent()"
    is not called at all if window size doesn't change, allowing for less
    cumbersome ofscreen rendering setups
-   Removed redundant operators from @ref Math::RectangularMatrix "Math::*Matrix",
    use vectors for component-wise multiplication and division instead
-   Documentation updates and improvements to make the library more accessible
    for newcomers
-   Various build system updates for better compile times and easier
    installation

    added shader compilation tests to prevent this issue from reappearing (see
    [mosra/magnum#17](https://github.com/mosra/magnum/issues/17))
-   Extension support queries depend on selected GLSL version (see
    [mosra/magnum-examples#3](https://github.com/mosra/magnum-examples/issues/3))

    into @cpp Math::swizzle() @ce
-   @cpp Buffer::setData() @ce and @cpp Buffer::setSubData() @ce overloads
    taking pair of data pointer and size are deprecated, use
    @cpp Containers::ArrayReference @ce-based @cpp Buffer::setData() @ce and
    @cpp Buffer::setSubData() @ce
-   `ImageFormat.h` header, @cpp ImageFormat @ce and @cpp ImageType @ce enums
    are deprecated, use `ColorFormat.h` header, `ColorFormat` and `ColorType`
    enums which reflect OpenGL naming better instead
-   @cpp Platform::*Application::InputEvent::Modifier::*Button @ce enum values
    are deprecated, use
