@section changelog-2018-04 2018.04

Released 2018-05-01, tagged as
[v2018.04](https://github.com/mosra/magnum/releases/tag/v2018.04).

@subsection changelog-2018-04-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-2018-04-new New features

-   New @ref PixelFormat / @ref CompressedPixelFormat enums containing generic
    API-independent pixel formats, together with @cpp pixelSize() @ce,
    @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-2018-04-new-math Math library

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

@subsubsection changelog-2018-04-new-gl GL library

-   A new library that now contains wrappers for the OpenGL family of graphics
    APIs, separated from the core Magnum library (see
    [mosra/magnum#233](https://github.com/mosra/magnum/pull/233))
-   New @ref GL::hasPixelFormat(), @ref GL::pixelFormat(), @ref GL::pixelType(),
    @ref GL::hasCompressedPixelFormat(), @ref GL::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 GL::BufferImage and
    @ref GL::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 GL::Mesh
    class now has overloads accepting both types.
-   New @ref GL::Mesh::indexType() and @ref GL::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 (see
    [mosra/magnum#224](https://github.com/mosra/magnum/issues/224),
    [mosra/magnum#231](https://github.com/mosra/magnum/pull/231))
-   New OpenGL extension support:
    -   @gl_extension{ARB,texture_filter_anisotropic}
    -   @gl_extension{OES,texture_float}, @gl_extension2{OES,texture_half_float,OES_texture_float}
    -   @gl_extension{EXT,color_buffer_float},
        @gl_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 GL::OpenGLTester to WebGL

@subsubsection changelog-2018-04-new-platform Platform libraries

-   Ability to create @ref Platform::Sdl2Application and
    @ref Platform::GlfwApplication classes without implicitly created OpenGL
    context by passing @ref Platform::Sdl2Application::Configuration::WindowFlag::Contextless "Configuration::WindowFlag::Contextless"
    to them. These two can be now also built completely without the GL library.
-   Added @ref Platform::AndroidApplication::windowSize()
-   Added @ref Platform::AndroidApplication::nativeActivity() to access
    underlying `ANativeActivity` structure for calling various Android APIs

@subsubsection changelog-2018-04-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-2018-04-new-trade Trade library

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

@subsection changelog-2018-04-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-2018-04-changes-debugtools DebugTools library

-   @ref DebugTools::textureSubImage() now accepts both GL-specific
    @ref GL::PixelFormat / @ref GL::PixelType combination and the generic
    @ref PixelFormat enum
-   @ref DebugTools::CompareImage now accepts generic @ref PixelFormat on input
    instead of GL-specific @ref GL::PixelFormat / @ref GL::PixelType

@subsubsection changelog-2018-04-changes-gl GL library

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

@subsubsection changelog-2018-04-changes-text Text library

-   The @cpp Text::GlyphCache @ce now unconditionally uses
    @ref GL::TextureFormat::Luminance on ES2 and WebGL 1, instead of trying
    @ref GL::TextureFormat::Red there first. That's done for consistency with
    @ref GL::pixelFormat(), which unconditionally returns
    @ref GL::PixelFormat::Luminance for @ref PixelFormat::R8Unorm.

@subsubsection changelog-2018-04-changes-platform Platform libraries

-   Separated @ref Platform::Sdl2Application::Configuration "Platform::*Application::Configuration"
    into @ref Platform::Sdl2Application::Configuration "Configuration" and
    @ref Platform::Sdl2Application::GLConfiguration "GLConfiguration" to allow
    creation of non-GL application instances in the future

@subsubsection changelog-2018-04-changes-plugins Plugins

-   @ref Trade::TgaImporter "TgaImporter" and
    @ref Trade::TgaImageConverter "TgaImageConverter" plugins now operate on
    the generic @ref PixelFormat instead of GL-specific @ref GL::PixelFormat /
    @ref GL::PixelType
-   @ref Trade::AnySceneImporter "AnySceneImporter" now uses `GlbImporter` for
    loading binary glTF files instead of proxying them to `GltfImporter`
    plugins

@subsection changelog-2018-04-buildsystem Build system

-   The core @ref Magnum library is not depending on OpenGL anymore, all
    GL-related APIs are now part of a new @ref GL library
-   @ref Primitives and @ref Trade libraries do not depend on OpenGL anymore
-   @ref DebugTools, @ref MeshTools and @ref TextureTools have only an optional
    dependency on the @ref GL library, controlled with `TARGET_GL` CMake option
-   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. See also [mosra/magnum#235](https://github.com/mosra/magnum/issues/235).
-   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
-   Suppressed a MSVC warning in @ref MeshTools::interleave() (see
    [mosra/magnum#238](https://github.com/mosra/magnum/issues/238))
-   Fixed Vcpkg packages to properly copy all plugin and their dependencies
    along the executable (see [mosra/magnum#235](https://github.com/mosra/magnum/issues/235),
    [mosra/magnum-examples#41](https://github.com/mosra/magnum-examples/issues/41))
-   Stable version of Magnum is now available as a binary package in the
    ArchLinux `[community]` repo
-   Homebrew macOS packages were updated to install the stable version by
    default
-   Fixed the Debian package after introducing `SOVERSION` to all libraries
    (see [mosra/magnum#237](https://github.com/mosra/magnum/issues/237))
-   Fixed the Debian package to not include a revision. While just a warning on
    Ubuntu, it's a hard error on Debian. (See [mosra/corrade#44](https://github.com/mosra/corrade/issues/44).)

@subsection changelog-2018-04-bugfixes Bug fixes

-   Engine startup info was not properly printed to Android log since
    introducing the `--magnum-log` option in version 2018.02
-   Dropped Google Closure Compiler from Emscripten toolchains, it was bringing
    more harm than good (see [mosra/magnum#211](https://github.com/mosra/magnum/issues/211))
-   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 and [mosra/magnum#239](https://github.com/mosra/magnum/issues/239)
    for details.
-   @cpp GL::Attribute::DataType::HalfFloat @ce was not available on WebGL 2 by
    mistake
-   A wrong code path for @ref GL::Framebuffer::checkStatus() was selected on
    WebGL 1 by mistake
-   Fixed `MAGNUM_PLUGINS_DIR` variables to contain proper absolute location by
    default again.

@subsection changelog-2018-04-deprecated Deprecated APIs

-   All GL-related headers and APIs from the root `Magnum/` directory and
    @ref Magnum namespace were moved to the `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
-   `Platform::*Application::createContext()` and

    being too GL-specific, use @ref Platform::Sdl2Application::create() "create()"
    and @ref Platform::Sdl2Application::tryCreate() "tryCreate()" instead
-   The `Extensions::GL` namespace is deprecated, use @ref GL::Extensions
    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.
-   `PixelStorage::pixelSize()` was deprecated, use @cpp GL::pixelSize() @ce
    or @cpp Magnum::pixelSize() @ce 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 @cpp GL::pixelSize() @ce 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 @ref 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
    @cpp GL::Mesh::indexTypeSize() @ce 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

-   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

    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
    @cpp Shaders::*Vector::bindVectorTexture() @ce,
    @cpp Shaders::Flat::bindTexture() @ce,
    @cpp Shaders::Phong::bindAmbientTexture() @ce,
    @cpp Shaders::Phong::bindDiffuseTexture() @ce,
    @cpp Shaders::Phong::bindSpecularTexture() @ce
    and @cpp Shaders::Phong::bindTextures() @ce instead.

@subsection changelog-2018-04-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.
-   The `Magnum::Context` target alias was renamed to `Magnum::GLContext`. No
    backwards compatibility 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,
    `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
-   @ref DebugTools::CompareImage no longer accepts GL-specific pixel formats,
    only the non-deprecated values from the generic @ref PixelFormat enum
-   The @ref Trade::TgaImageConverter "TgaImageConverter" plugin no longer
    accepts GL-specific pixel formats, only the non-deprecated values from the
    generic @ref PixelFormat enum
-   The @ref Image::pixelSize(), @ref ImageView::pixelSize(),
    @ref Trade::ImageData::pixelSize() and @ref GL::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 GL::BufferUsage enum instead
-   Removed the `Magnum/Query.h` header that was deprecated in 2015.05, use one
    of `Magnum/PrimitiveQuery.h`, `Magnum/SampleQuery.h` or
    `Magnum/TimeQuery.h` instead
-   Removed ability to use @ref GL::Buffer::Target as constructor or
    @ref GL::Buffer::setTargetHint() parameter that was deprecated in 2015.05,
    use @ref GL::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 GL::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 GL::AbstractShaderProgram::maxVertexAttributes()
    instead
-   Removed @cpp Math::Vector::dot() @ce, @cpp Math::Complex::dot() @ce,
    @cpp Math::Quaternion::dot() @ce, @cpp Math::Vector::angle() @ce,
    @cpp Math::Complex::angle() @ce, @cpp Math::Quaternion::angle() @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 GL::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 GL::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/GL/DebugOutput.h instead
-   Removed the @cpp DebugMessage::Severity @ce enum that was deprecated in
    2015.05, use @ref GL::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 GL::DebugOutput::Callback,
    @ref GL::DebugOutput::setCallback() and
    @ref GL::DebugOutput::setDefaultCallback() instead

    [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 GL::Texture::image() "*Texture::image()" and
    @ref GL::Framebuffer::read() "*Framebuffer::read()"
    now reallocate image data only if needed, for both @ref Image and
    @ref GL::BufferImage "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 GL::Framebuffer::read() "Framebuffer::read()" directly to
    @cpp Trade::AbstractImageConverter::exportToFile() @ce)
-   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 GL::Buffer::map() "Buffer::map()" now returns
    @ref Corrade::Containers::ArrayView instead of a plain pointer for better
    security
-   Improved @ref GL::Context::resetState() "Context::resetState()" to better
    handle corner cases with VAOs
-   Graceful handling of broken GL contexts
-   Behavior of @ref GL::Version::GLES200 "Version::GLES200" and upwards on
    desktop OpenGL is changed to request an ES dialect of GLSL when used in
    @ref GL::Shader "Shader" (instead of a particular desktop GL version that
    supports given ES version), looks for @gl_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
    @gl_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 GL::Texture::setImage() "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
-   @ref Math::Matrix4::transformPoint() now properly uses the perspective
    divide from projection matrices
-   Updated @ref Math::TypeTraits fuzzy comparison epsilon values for
    @cpp long double @ce and @cpp double @ce

@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

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

-   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).

-   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)

-   Fixed @ref GL::Framebuffer "Framebuffer" binding on WebGL (see
    [mosra/magnum#134](https://github.com/mosra/magnum/pull/134))
-   On Emscripten, @ref Platform::Sdl2Application was by default rendering a

    are now a namespace (might break `using` declarations, but otherwise it's
    fully source-compatible)
-   Removed `Context::majorVersion()` and `Context::minorVersion()` functions,
    use @ref GL::Context::version() instead
-   Removed deprecated `Magnum/DebugMarker.h` header, use
    `Magnum/DebugOutput.h` and @ref GL::DebugMessage "DebugMessage" class
    instead
-   Removed deprecated `*Buffer` values from
    @ref GL::FramebufferBlit "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

    @ref GL::Shader::maxCombinedTextureImageUnits() "Shader::maxCombinedTextureImageUnits()"
    instead
-   Removed deprecated @cpp MeshTools::combineIndexedArrays() @ce,
    @ref MeshTools::compressIndices(), @ref MeshTools::interleave() and
    @cpp MeshTools::removeDuplicates() @ce overloads, use the general ones
    instead

    @ref GL::Texture "Texture", @ref GL::TextureArray "TextureArray",
    @ref GL::RectangleTexture "RectangleTexture" and
    @ref GL::MultisampleTexture "MultisampleTexture" classes instead

    @ref GL::Framebuffer::attachTextureLayer() "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.

-   Using [flextGL](https://github.com/ginkgo/flextgl) instead of `glLoadGen`
    for OpenGL extension loading
-   @ref Platform::Sdl2Application now tries to create core context on all
    platforms, not just OSX (see [mosra/magnum#80](https://github.com/mosra/magnum/issues/80)).
-   @cpp Buffer::bind() @ce, @cpp Buffer::unbind() @ce and @cpp Buffer::Target @ce
    is now used for indexed buffer binding only.
-   Moved static binary operations from @ref Math classes into free functions
    for more convenient usage (see [mosra/magnum#74](https://github.com/mosra/magnum/issues/74)).
-   Better algorithm for comparing floating-point values.
-   Ensuring that all OpenGL objects are properly created before using them.
-   Using @cpp const char @ce instead of @cpp const unsigned char @ce for raw
    binary data.
-   Removed annoying restriction when adding reference-counted resources to
    @ref ResourceManager.
-   Extension querying cleanup:
    -   Removed @gl_extension{APPLE,flush_buffer_range} extension.
    -   Replaced @gl_extension{APPLE,vertex_array_object} with
        @gl_extension{ARB,vertex_array_object}.
    -   Replaced @gl_extension{NV,half_float} with @gl_extension{ARB,half_float_vertex}.
    -   Replaced @gl_extension{EXT,framebuffer_sRGB} with @gl_extension{ARB,framebuffer_sRGB}.
-   Documentation cleanup, fixes and improvements.

@subsection changelog-2015-05-buildsystem Build system

-   CMake now always installs `FindMagnum.cmake` to library-specific
    location, making it usable without providing own copy of the file in
    depending projects. The `WITH_FIND_MODULE` option is no longer needed.
-   CMake now handles inter-library dependencies automatically without manually
    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)).

    taking list of references 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
-   @cpp MeshTools::combineIndexedArrays() @ce taking @ref std::tuple is
    deprecated, use version taking @ref std::pair instead
-   @cpp MeshTools::removeDuplicates() @ce taking also list of indices is

        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

    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

    compatible shader
-   Convenience @cpp hasNormals() @ce, @cpp hasTextureCoords2D() @ce functions
    in @cpp Trade::MeshData2D @ce and @cpp Trade::MeshData3D @ce
-   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

    @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 @cpp Shaders::Flat @ce 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 @cpp Shaders::Flat @ce 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 @cpp Text::Renderer @ce 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),
    [mosra/magnum#16](https://github.com/mosra/magnum/issues/16),

    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

    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))
