@section changelog-latest Changes since 2018.02

@subsection changelog-latest-dependencies Dependency changes

-   Building for Android now requires CMake 3.7 with builtin Android
    crosscompilation support, the old toolchains were removed. Only the Clang
    and libc++ toolchain is now supported, support for GCC and libstdc++ was
    dropped, as it was still missing some important C++11 functionality. See
    @ref building-cross-android for more information.

@subsection changelog-latest-new New features

-   New @ref PixelFormat / @ref CompressedPixelFormat enums containing generic
    API-independent pixel formats, together with @ref pixelSize(),
    @ref pixelFormatWrap() / @ref pixelFormatUnwrap(),
    @ref compressedPixelFormatWrap() / @ref compressedPixelFormatUnwrap() and @ref isPixelFormatImplementationSpecific() /
    @ref isCompressedPixelFormatImplementationSpecific() utilities now used by
    @ref Image / @ref CompressedImage and @ref ImageView /
    @ref CompressedImageView instead of the GL-specific formats
-   New @ref MeshPrimitive and @ref MeshIndexType enums containing generic
    API-independent mesh primitive types and index types, together with
    @ref meshIndexTypeSize() utilities
-   New @ref SamplerFilter, @ref SamplerMipmap and @ref SamplerWrapping enums
    containing generic API-independent texture sampler modes

@subsubsection changelog-latest-new-math Math library

-   Added @ref Math::isInf(), @ref Math::isNan()

@subsubsection changelog-latest-new-gl GL library

-   A new library that now contains wrappers for the OpenGL family of graphics
    APIs, separated from the core Magnum library
-   New @ref GL::hasPixelFormat(), @ref GL::pixelFormat(), @ref GL::pixelType(),
    @ref GL::hasCompressedPixelFormat(), @ref compressedPixelFormat() utilities
    for converting generic @ref PixelFormat / @ref CompressedPixelFormat to
    GL-specific @ref GL::PixelFormat, @ref GL::PixelType and
    @ref GL::CompressedPixelFormat values. The @ref BufferImage and
    @ref CompressedBufferImage classes now have overloads accepting both types.
-   New @ref GL::meshPrimitive() and @ref GL::meshIndexType() utilities for
    converting generic @ref MeshPrimitive and @ref MeshIndexType to GL-specific
    @ref GL::MeshPrimitive and @ref GL::MeshIndexType values. The @ref Mesh
    class now has overloads accepting both types.
-   New @ref Mesh::indexType() and @ref MeshView::mesh() getters
-   New @ref GL::samplerFilter(), @ref GL::samplerMipmap() and
    @ref GL::samplerWrapping() utilities for converting generic
    @ref SamplerFilter, @ref SamplerMipmap and @ref SamplerWrapping to G
    L-specific @ref GL::SamplerFilter, @ref GL::SamplerMipmap and
    @ref GL::SamplerWrapping values. All texture classes now have overloads
    accepting both types.
-   Initial support for OpenGL ES 3.2 and OpenGL 4.6
-   New OpenGL extension support:
    -   @extension{ARB,texture_filter_anisotropic}
    -   @extension{OES,texture_float}, @extension2{OES,texture_half_float,OES_texture_float}
    -   @extension{EXT,color_buffer_float},
        @extension2{EXT,color_buffer_half_float,EXT_color_buffer_half_float}
        and
        their WebGL counterparts @webgl_extension{EXT,color_buffer_half_float},
        @webgl_extension{WEBGL,color_buffer_float},
        @webgl_extension{EXT,color_buffer_float}
-   Ported @ref OpenGLTester to WebGL

@subsubsection changelog-latest-new-platform Platform libraries

-   Added @ref Platform::AndroidApplication::windowSize()
-   Added @ref Platform::AndroidApplication::nativeActivity() to access
    underlying `ANativeActivity` structure for calling various Android APIs

@subsubsection changelog-latest-new-primitives Primitives library

-   New @ref Primitives::circle3DSolid(), @ref Primitives::circle3DWireframe(),
    @ref Primitives::coneSolid(), @ref Primitives::coneWireframe(),
    @ref Primitives::grid3DSolid() and @ref Primitives::grid3DWireframe()
    primitives

@subsubsection changelog-latest-new-trade Trade library

-   Debug output operator for @ref Trade::PhongMaterialData::Flag and
    @ref Trade::PhongMaterialData::Flags

@subsection changelog-latest-changes Changes and improvements

-   The @ref CompressedPixelStorage class and related APIs are now available
    on all targets including OpenGL ES and WebGL, however at the moment, until
    a compatibility code path is implemented, the @ref GL library expects that
    all parameters are at their defaults.

@subsubsection changelog-latest-changes-gl GL library

-   The @ref GL::Mesh::indexTypeSize() and @ref GL::MeshView::setIndexRange()
    now expect that the mesh is indexed (instead of silently not doing
    anything)

@subsection changelog-latest-buildsystem Build system

-   All plugin interfaces now implement
    @ref Corrade::PluginManager::AbstractPlugin::pluginSearchPaths() "pluginSearchPaths()"
    for plugin directory autodetection --- you no longer need to specify the
    plugin directory explicitly when loading plugins. See @ref plugins-loading
    for more information.
-   Plugins now provide an automatic means of static plugin import via CMake
    targets, no need to call @ref CORRADE_PLUGIN_IMPORT() implicitly anymore.
    For this to work, you just need to update local copies of all Find modules.
    See @ref plugins-static for more information.
-   The @ref Audio::AnyImporter "AnyAudioImporter", @ref Trade::AnyImageConverter "AnyImageConverter",
    @ref Trade::AnyImageImporter "AnyImageImporter" and @ref Trade::AnySceneImporter "AnySceneImporter"
    plugins were moved from the plugins repository to the core Magnum
    repository. If you are using them statically via CMake, you need to update
    your copies of `FindMagnum.cmake` and `FindMagnumPlugins.cmake` modules.
    See @ref building and @ref cmake for more information.
-   The @ref Trade namespace is now a separate library, allowing to use core
    Magnum functionality without @ref Corrade::PluginManager
-   Fixed the Debian package to not include a revision. While just a warning on
    Ubuntu, it's a hard error on Debian.

@subsection changelog-latest-bugfixes Bug fixes

-   Engine startup info was not properly printed to Android log since
    introducing the `--magnum-log` option in version 2018.02
-   Working around Emscripten issue where `-s USE_PTHREADS=1` would cause all
    shader sources containing Unicode characters to be truncated to empty
    strings. See the @cpp "emscripten-pthreads-broken-unicode-shader-sources" @ce
    workaround description for details.
-   @ref Attribute::DataType::HalfFloat was not available on WebGL 2 by mistake
-   A wrong code path for @ref Framebuffer::checkStatus() was selected on WebGL
    1 by mistake
-   Fixed `MAGNUM_PLUGINS_DIR` variables to contain proper absolute location by
    default again.

@subsection changelog-latest-deprecated Deprecated APIs

-   All GL-related headers and APIs from the root @ref Magnum/ directory and
    @ref Magnum namespace were moved to @ref Magnum/GL directory and
    @ref Magnum::GL namespace. See their documentation for information about
    particular files, classes, enums, typedefs, values and functions.
-   The `MAGNUM_ASSERT_VERSION_SUPPORTED()`, `MAGNUM_ASSERT_EXTENSION_SUPPORTED()`
    and `MAGNUM_VERIFY_NO_ERROR()` macros are deprecated, use
    @ref MAGNUM_ASSERT_GL_VERSION_SUPPORTED(),
    @ref MAGNUM_ASSERT_GL_EXTENSION_SUPPORTED() and
    @ref MAGNUM_VERIFY_NO_GL_ERROR() instead
-   The `Platform::Context` class is deprecated, use @ref Platform::GLContext
    instead
-   The @ref PixelFormat and @ref CompressedPixelFormat enum now contains
    generic API-independent values. The GL-specific formats are present there,
    but marked as deprecated. Use either the generic values or
    @ref GL::PixelFormat (together with @ref GL::PixelType) and
    @ref GL::CompressedPixelFormat instead.
-   @ref PixelStorage::pixelSize() was deprecated, use @ref GL::pixelSize()
    or @ref Magnum::pixelSize() instead
-   `PixelStorage::dataProperties(GL::PixelFormat, GL::PixelSize, const Vector3i&)`
    was deprecated for being too GL-specific, use
    @ref PixelStorage::dataProperties(std::size_t, const Vector3i&) const
    together with @ref GL::pixelSize() instead
-   `Image*::type()` functions are deprecated as these are too GL-specific. The
    second format specifier is now available through @ref Image::formatExtra(),
    @ref ImageView::formatExtra() and @ref Trade::ImageData::formatExtra()
-   `Audio::Buffer::Format` is deprecated, use `Audio::BufferFormat` instead
-   `setData()` functions in the @ref Image and @ref CompressedImage classes
    are deprecated because they don't offer anything extra over simple
    move-assignment of a new instance.
-   The @ref MeshPrimitive enum now contains generic API-independent values.
    The additional GL-specific types are present there, but marked as
    deprecated. Use the GL-specific @ref GL::MeshPrimitive enum instead.
-   THe `GL::Mesh::IndexType` enum and the `Mesh::indexSize(MeshIndexType)`
    function is deprecated, use @ref Magnum::MeshIndexType /
    @ref GL::MeshIndexType and @ref meshIndexTypeSize() instead
-   The `GL::Mesh::indexSize()` function is deprecated, use
    @ref GL::Mesh::indexTypeSize() instead
-   The `Sampler` class and the `Sampler::Filter`, `Sampler::Mipmap`,
    `Sampler::Wrapping`, `Sampler::CompareMode`, `Sampler::CompareFunction` and
    `Sampler::DepthStencilMode` enums are deprecated, use @ref GL::Sampler,
    @ref SamplerFilter / @ref GL::SamplerFilter, @ref SamplerMipmap /
    @ref GL::SamplerMipmap, @ref SamplerWrapping / @ref GL::SamplerWrapping,
    @ref GL::SamplerCompareMode, @ref GL::SamplerCompareFunction and
    @ref GL::SamplerDepthStencilMode instead
-   Class @cpp Primitives::Capsule2D @ce and @cpp Primitives::Capsule3D @ce is
    deprecated, use @ref Primitives::capsule2DWireframe(),
    @ref Primitives::capsule3DSolid() and @ref Primitives::capsule3DWireframe()
    free functions instead
-   Class @cpp Primitives::Circle @ce is deprecated, use
    @ref Primitives::circle2DSolid() and @ref Primitives::circle2DWireframe()
    instead
-   Class @cpp Primitives::Crosshair2D @ce and @cpp Primitives::Crosshair3D @ce
    is deprecated, use @ref Primitives::crosshair2D() and
    @ref Primitives::crosshair3D() free function instead
-   Class @cpp Primitives::Cube @ce is deprecated, use @ref Primitives::cubeSolid(),
    @ref Primitives::cubeSolidStrip() and @ref Primitives::cubeWireframe() free
    functions instead
-   Class @cpp Primitives::Cylinder @ce is deprecated, use
    @ref Primitives::cylinderSolid(), @ref Primitives::cylinderWireframe() free
    functions instead
-   Class @cpp Primitives::Icosphere @ce is deprecated, use the
    @ref Primitives::icosphereSolid() free function instead
-   Class @cpp Primitives::Plane @ce is deprecated, use
    @ref Primitives::planeSolid() and @ref Primitives::planeWireframe() free
    functions instead
-   Class @cpp Primitives::Square @ce is deprecated, use
    @ref Primitives::squareSolid() and @ref Primitives::squareWireframe() free
    functions instead
-   Class @cpp Primitives::UVSphere @ce is deprecated, use
    @ref Primitives::uvSphereSolid() and @ref Primitives::uvSphereWireframe()
    free functions instead
-   @cpp Shaders::*Vector::setVectorTexture() @ce, @cpp Shaders::Flat::setTexture() @ce,
    @cpp Shaders::Phong::setAmbientTexture() @ce, @cpp Shaders::Phong::setDiffuseTexture() @ce,
    @cpp Shaders::Phong::setSpecularTexture() @ce and @cpp Shaders::Phong::setTextures() @ce
    are deprecated because texture binding (a global state) is confused there
    with uniform setup (a shader-local state). That can lead to accidental
    state mismatches where a texture is forgotten to be rebound. Use
    @ref Shaders::AbstractVector::bindVectorTexture() "Shaders::*Vector::bindVectorTexture()",
    @ref Shaders::Flat::bindTexture(), @ref Shaders::Phong::bindAmbientTexture(),
    @ref Shaders::Phong::bindDiffuseTexture(), @ref Shaders::Phong::bindSpecularTexture()
    and @ref Shaders::Phong::bindTextures() instead.

@subsection changelog-latest-compatibility Potential compatibility breakages, removed APIs

-   Code that was previously linking just to the core @ref Magnum library may
    now need to explicitly link to the @ref Magnum::Trade and @ref Magnum::GL
    libraries as well. If using CMake, these dependencies might get linked in
    transitively from other libraries, but that doesn't handle all cases. Due
    to the complexity of this change, no backwards compatibility is provided.
-   The `magnum-info` utility was renamed to @ref magnum-gl-info. No backwards
    compatibility symlinks or aliases are provided.
-   @ref PixelStorage::dataProperties(), @ref Image::dataProperties(),
    @ref ImageView::dataProperties(), @ref Trade::ImageData::dataProperties(), and @ref GL::BufferImage::dataProperties() now return just a pair of two
    values, as the third value is now accessible directly through
    @ref Image::pixelSize() "*Image::pixelSize()" and no longer calculated
    on-demand
-   @ref CompressedPixelStorage::dataProperties(),
    @ref CompressedImage::dataProperties(),
    @ref CompressedImageView::dataProperties() and
    @ref GL::CompressedBufferImage::dataProperties() now return just a pair
    of two values, as the third value is accessible directly through
    @ref CompressedPixelStorage::compressedBlockDataSize()
-   @ref ImageView and @ref CompressedImageView methods are no longer
    @cpp constexpr @ce. It might be possible to have them @cpp constexpr @ce in
    C++14, but the resulting increase in maintenance costs and compile times is
    not worth it.
-   `PixelFormat` has been moved verbatim to @ref GL::PixelFormat and there's a
    new @ref Magnum::PixelFormat enum for generic pixel formats. It contains
    (deprecated) @ref GL::PixelFormat values for covering most of backwards
    compatibility, but code that relies on these two types being the same may
    break. In particular, @ref GL::BufferImage::format() now returns
    @ref GL::PixelFormat instead of @ref Magnum::PixelFormat, code depending on
    the return type being implicitly convertible to @ref Magnum::PixelFormat
    may break. In all other cases, @ref Image::format() "Image*::format()"
    returns @ref Magnum::PixelFormat.
-   `CompressedPixelFormat` has been moved verbatim to
    @ref GL::CompressedPixelFormat and there's a new
    @ref Magnum::CompressedPixelFormat enum for generic pixel formats. It
    contains (deprecated) @ref GL::CompressedPixelFormat values for covering
    most of backwards compatibility, but code that relies on these two types
    being the same may break. In particular,
    @ref GL::CompressedBufferImage::format()  now returns
    @ref GL::CompressedPixelFormat instead of @ref Magnum::CompressedPixelFormat,
    code depending on the return type being implicitly convertible to
    @ref Magnum::CompressedPixelFormat may break. In all other cases,
    @ref CompressedImage::format() "CompressedImage*::format()"
    returns @ref Magnum::CompressedPixelFormat.
-   `MeshPrimitive` has been moved verbatim to @ref GL::MeshPrimitive and
    there's a new @ref Magnum::MeshPrimitive enum for generic primitive types.
    It contains (deprecated) additional @ref GL::MeshPrimitive values for
    covering most of backwards compatibility, but code that relies on these
    two types being the same (or have values that match GL enums) may break.
    In particular, @ref GL::Mesh::primitive() now returns
    @ref GL::MeshPrimitive instead of @ref Magnum::MeshPrimitive, code
    depending on the return type being implicitly convertible to
    @ref Magnum::MeshPrimitive may break. IN all other cases,
    @ref Trade::MeshData2D::primitive() "Trade::MeshData*D::primitive()" etc.
    returns @ref Magnum::MeshPrimitive.
-   Configuration value reader/writers are now for only
    @ref Magnum::MeshPrimitive and @ref Magnum::MeshIndexType, not for
    @ref GL::MeshPrimitive or @ref GL::MeshIndexType
-   The @ref Image::pixelSize(), @ref ImageView::pixelSize(),
    @ref Trade::ImageData::pixelSize() and @ref BufferImage::pixelSize()
    functions now return @ref UnsignedInt instead of @cpp std::size_t @ce.
-   Removed `PixelStorage::setSwapBytes()`, as every Magnum API dealing with
    images basically only asserted that it's not set. Use
    @ref Corrade::Utility::Endianness instead.
-   Removed the @cpp Buffer::Usage @ce enum that was deprecated in 2014.01, use
    the global @ref BufferUsage enum instead
-   Removed the `Magnum/Query.h` header that was deprecated in 2015.05, use one
    of @ref Magnum/PrimitiveQuery.h, @ref Magnum/SampleQuery.h or
    @ref Magnum/TimeQuery.h instead
-   Removed ability to use @ref Buffer::Target as constructor or
    @ref Buffer::setTargetHint() parameter that was deprecated in 2015.05, use
    @ref Buffer::TargetHint instead
-   Removed the @cpp SceneGraph::TransformationType @ce enum that was
    deprecated in 2015.05, use separate `<transform>()` and `<transform>Local()`
    variants instead
-   Removed @cpp SceneGraph::AbstractObject::hasFeatures() @ce, @cpp firstFeature() @ce,
    @cpp lastFeature() @ce, @cpp SceneGraph::Object::hasChildren() @ce,
    @cpp firstChild() @ce and @cpp lastChild() @ce that were deprecated in
    2015.05, use methods on linked list returned by
    @ref SceneGraph::AbstractObject::features() and
    @ref SceneGraph::Object::children() instead
-   Removed @cpp Platform::ScreenedApplication::frontScreen() @ce and
    @cpp Platform::ScreenedApplication::backScreen() @ce that were deprecated
    in 2015.05, use methods on linked list returned by
    @ref Platform::BasicScreenedApplication::screens() "Platform::ScreenedApplication::screens()"
    instead
-   Removed @ref Framebuffer::read() "*Framebuffer::read()" functions taking two
    vectors that was deprecated in 2015.05, use overload taking @ref Range2Di
    instead
-   Removed the @cpp Mesh::maxVertexAttributes() @ce function that was
    deprecated in 2015.05, use @ref AbstractShaderProgram::maxVertexAttributes()
    instead
-   Removed @cpp Math::Vector::dot() @ce, @cpp Math::Complex::dot() @ce,

    @cpp Math::Quaternion::lerp() @ce, @cpp Math::Quaternion::slerp() @ce,
    @cpp Math::Vector2::cross() @ce and @cpp Math::Vector3::cross() @ce that
    were deprecated in 2015.05, use @ref Math::dot(), @ref Math::angle(),
    @ref Math::lerp(), @ref Math::slerp() and @ref Math::cross() instead
-   Removed @cpp *Framebuffer::bind(FramebufferTarget) @ce function that was
    deprecated in 2%15.05, use parameter-less @ref Framebuffer::bind() "*Framebuffer::bind()"
    instead
-   Removed @cpp FramebufferTarget::ReadDraw @ce enum value that was deprecated
    in 2015.05, use separate @cpp FramebufferTarget::Read @ce and
    @cpp FramebufferTarget::Draw @ce values instead
-   Removed @ref CubeMapTexture::imageSize() with explicit face parameter that
    was deprecated in 2015.05, use overload that returns one value for all
    faces instead
-   Removed the `Magnum/DebugMessage.h` header that was deprecated in 2015.05,
    use @ref Magnum/DebugOutput.h instead
-   Removed the @cpp DebugMessage::Severity @ce enum that was deprecated in
    2015.05, use @ref DebugOutput::Severity instead
-   Removed @cpp DebugMessage::Callback @ce typedef, @cpp DebugMessage::setCallback() @ce
    and @cpp DebugMessage::setDefaultCallback() @ce function that were
    deprecated in 2015.05, use @ref DebugOutput::Callback,
    @ref DebugOutput::setCallback() and @ref DebugOutput::setDefaultCallback()
    instead
-   Removed @cpp DebugMessage::maxLoggedMessages() @ce and
    @cpp DebugMessage::maxMessageLength() @ce functions that were deprecated in
    2015.05, use @ref DebugOutput::maxLoggedMessages() and
    @ref DebugOutput::maxMessageLength() instead
-   Removed @cpp DebugMessage::setEnabled() @ce function and related values
    from @cpp DebugMessage::Source @ce enum that were deprecated in 2015.05,
    use @ref DebugOutput::setEnabled() along with @ref DebugOutput::Source,
    @ref DebugOutput::Type and @ref DebugOutput::Severity instead
-   Removed parameter-less @cpp *Query @ce constructor and parametrized
    @cpp *Query::begin() @ce function that were deprecated in 2015.05, use
    constructor with parameter and parameter-less @ref Query::begin() "*Query::begin()"
    instead
-   Removed `Timeline::setMinimalFrameTime()` that was deprecated since June
    2015, use @ref Platform::Sdl2Application::setSwapInterval() "Platform::*Application::setSwapInterval()"
    and/or @ref Platform::Sdl2Application::setMinimalLoopPeriod() "Platform::*Application::setMinimalLoopPeriod()"
    instead

@subsection changelog-2018-02-changes Changes and improvements

-   Functionality that is not available on WebGL (like debug output etc.) is
    not present in WebGL builds to reduce compiled code size
-   The @ref Mesh class now stores a copy of @ref Buffer instance instead of
    reference, meaning that you can move your buffers freely after assigning
    them to a mesh
-   @ref Texture::setStorage() "*Texture::setStorage()" fallback implementation
    on OpenGL ES 2.0 and WebGL 1.0 now properly translates sized texture
    formats to what the drivers expect (see [mosra/magnum#214](https://github.com/mosra/magnum/issues/214))
-   @ref Trade::TgaImporter "TgaImporter" and @ref Trade::TgaImageConverter "TgaImageConverter"
    now consistently use RGB(A) on all platforms and don't require BGR(A) on
    desktop
-   Ignoring @cpp "No errors." @ce message produced by GLSL compiler/linker on
    Intel Windows drivers.
-   @ref Texture::image() "*Texture::image()" and @ref Framebuffer::read() "*Framebuffer::read()"
    now reallocate image data only if needed, for both @ref Image and
    @ref BufferImage types
-   R-value @ref Image "Image*" no longer restricts conversion to
    @ref ImageView as it is a valid use case (for example passing output from
    @ref Framebuffer::read() directly to @ref Trade::AbstractImageConverter::exportToFile())
-   It's no longer possible to call @ref Image::data() "Image*::data()" on
    r-value instances as that would cause accessing freed data. Use
    @ref Image::release() instead.
-   @ref Buffer::map() now returns @ref Corrade::Containers::ArrayView instead
    of a plain pointer for better security
-   Improved @ref Context::resetState() to better handle corner cases with VAOs
-   Graceful handling of broken GL contexts
-   Behavior of @ref Version::GLES200 and upwards on desktop OpenGL is changed
    to request an ES dialect of GLSL when used in @ref Shader (instead of a
    particular desktop GL version that supports given ES version), looks for
    @extension{ARB,ES2_compatibility} and others (instead of checking for a
    particular desktop GL version that supports given ES version)
-   Binding some default VAO in case the engine is running on core profile with
    @extension{ARB,vertex_array_object} disabled
-   It's now possible to create @ref ImageView with @cpp nullptr @ce data (for
    example for old-style texture allocation using @ref Texture::setImage())
-   Various workarounds to make the engine working better on SVGA3D drivers
    (VMWare guest)
-   Various updates and code modernization (see
    [mosra/magnum#200](https://github.com/mosra/magnum/pull/200))

@subsubsection changelog-2018-02-changes-math Math library

-   @ref Double types are no longer restricted to just desktop GL builds, all
    related types also work on ES and WebGL builds
-   Default-constructed @ref Color4 has zero alpha now instead of fully opaque
    black
-   Proper implementation of @ref Math::Vector::isZero() for integers

    @cpp long double @ce and @cpp double @ce
-   @ref Math::Matrix4::perspectiveProjection() now supports infinite far plane
-   @ref Math::pow() now works for both vectors and scalars
-   @ref Math::Vector::minmax() now works on arbitrary vectors instead of just
    @ref Math::Vector2

@subsubsection changelog-2018-02-changes-platform Platform library

-   Requesting core OpenGL context by default in @ref Platform::WindowlessGlxApplication
    and @ref Platform::Sdl2Application. On binary NVidia, AMD and Windows Intel
    drivers this causes the context to be stuck on OpenGL 3.1, in which case
    the context is destroyed and old-style forward-compatible context is
    requested instead.
-   @ref Platform::Sdl2Application now leaves windows positioning on the system
    instead of forcing the window to be centered
-   @ref Platform::Sdl2Application now shows the window only once the GL
    context is fully created to avoid flickering

@subsubsection changelog-2018-02-changes-shaders Shaders library

-   @ref Shaders::Flat now sets default color to white only in textured version
-   @ref Shaders::Phong gained the ability to have both color and texture
-   @ref Shaders::Phong is now able to do alpha-masking (see
    [mosra/magnum#112](https://github.com/mosra/magnum/issues/112),
    [mosra/magnum-examples#29](https://github.com/mosra/magnum-examples/issues/29))

    iOS, Android and Emscripten on [Travis CI](https://travis-ci.org/mosra/magnum)
    and [AppVeyor CI](https://ci.appveyor.com/project/mosra/magnum), with code
    coverage on [codecov.io](https://codecov.io/gh/mosra/magnum); replacing the
    unmaintained and outdated Jenkins configuration (see

-   Support for CMake subprojects. You can now clone Magnum into a subdirectory
    in your project and add it using @cmake add_subdirectory() @ce. The
    @cmake find_package() @ce command will then use the CMake subproject
    instead of looking for it in system-wide locations. See
    [mosra/magnum#49](https://github.com/mosra/magnum/issues/49).
    [mosra/magnum#140](https://github.com/mosra/magnum/issues/140).

    `MAGNUM_PLUGINS_DIR` CMake cache variable
-   Ability to override deploy directory (used for example by Emscripten) using
    a `MAGNUM_DEPLOY_PREFIX` CMake cache variable
-   Better handling of compiled-in resources in static build. You don't need to
    manually register resources when using Shaders library in static builds
    (see [mosra/magnum-examples#9](https://github.com/mosra/magnum-examples/issues/9))
-   `MACOSX_RPATH` is now enabled by default on CMake 3.0+ (see
    [mosra/magnum#126](https://github.com/mosra/magnum/pull/126)

@subsection changelog-2018-02-compatibility Potential compatibility breakages, removed APIs

-   The @ref Math::Geometry::Distance and @ref Math::Geometry::Intersection
    classes are now a namespace (might break `using` declarations, but
    otherwise it's fully source-compatible)
-   Removed `Context::majorVersion()` and `Context::minorVersion()` functions,
    use @ref Context::version() instead
-   Removed deprecated `Magnum/DebugMarker.h` header, use
    @ref Magnum/DebugOutput.h and @ref DebugMessage class instead
-   Removed deprecated `*Buffer` values from @ref FramebufferBlit, use values
    without the `Buffer` suffix
-   Removed deprecated list-argument functions taking pointers from @ref Audio
    and @ref SceneGraph libraries, use lists of references instead
-   Removed deprecated texture unit enums from @ref Shaders library, use
    dedicated texture setters instead
-   Removed deprecated `*Texture::maxLayers()` functions, use
    @ref Shader::maxCombinedTextureImageUnits() instead
-   Removed deprecated @ref MeshTools::combineIndexedArrays(),
    @ref MeshTools::compressIndices(), @ref MeshTools::interleave() and
    @ref MeshTools::removeDuplicates() overloads, use the general ones instead
-   Removed deprecated `Mesh*::set*{Range,Count}()` functions, use
    @ref Mesh::setCount() "Mesh*::setCount()" and @ref MeshView::setIndexRange()
    instead
-   Removed deprecated parameterless @ref Mesh::draw() "Mesh*::draw()"
    overload, use the one with explicit shader parameter instead
-   Removed deprecated `Context::Flag::Robustness` enum value, use
    @ref Context::Flag::RobustAccess instead
-   Removed deprecated `Texture::Target` enum, use dedicated @ref Texture,
    @ref TextureArray, @ref RectangleTexture and @ref MultisampleTexture
    classes instead
-   Removed deprecated @ref Resource conversion operator, use explicit
    conversion instead
-   Removed deprecated `Framebuffer::attachTexture*D()` overloads, use one of
    @ref Framebuffer::attachTexture() or @ref Framebuffer::attachTextureLayer()
    overloads instead.
-   Removed `SceneGraph::Camera3D::near()` and `SceneGraph::Camera3D::far()`
    getters, because they can't be provided anymore with current more general
    implementation. THe user is advised to cache the values on application side
    if they are really needed.
-   Removed `AbstractImage` class and `Magnum/AbstractImage.h` header, its
    functionality is present in the @ref Image "Image*" classes directly
-   Removed `Image::dataSize()` function as it has ambiguous meaning in regards
    to recently added features, use @ref Image::dataProperties() "Image::dataProperties()"
    instead
-   The `FindGLFW.cmake` now prefers absolute includes (i.e. `GLFW/glfw3.h`
    instead of just `glfw3.h`). The @ref Platform::GlfwApplication now depends
    on this, so be sure to update your copy to avoid build issues.
