@section changelog-latest Changes since 2018.02

@subsection changelog-latest-new New features

-   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}

@subsection changelog-latest-deprecated Deprecated APIs

-   @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()

@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
-   @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
-   @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

    [mosra/magnum#203](https://github.com/mosra/magnum/pull/203))
-   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).
-   Reworked CMake buildsystem to use the new imported target workflow, see
    @ref cmake for more information (see

-   Ability to build OpenGL tests also on Windows and macOS (see `BUILD_GL_TESTS`
    @ref building-features "CMake option")
-   Ability to override the implicit plugin directory using a
    `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)
-   Enabling only C++ in CMake @cmake project() @ce call, if possible, to speed
    up initial CMake run

-   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

    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

    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

    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.

    @ref Mesh::setCount() function instead
-   @cpp MeshView::setVertexRange() @ce and four-/two-argument
    @cpp MeshView::setIndexRange() @ce are deprecated for similar reason as
    above, use @ref MeshView::setCount(), @ref MeshView::setBaseVertex()
    and three-/one-argument @ref MeshView::setIndexRange() instead

    taking @ref std::initializer_list of pointers are deprecated, use versions
    taking list of references instead
-   @ref MeshTools::compressIndices() and @ref MeshTools::interleave()
    which filled @ref Mesh and @ref Buffer 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 @ref Mesh::draw() and @ref MeshView::draw() 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.
-   Texture binding using @ref Texture::bind() "*Texture::bind()" is
    deprecated, use setup functions of particular shaders instead (e.g.
    @ref Shaders::Phong::setDiffuseTexture())

    @ref Context::Flag::RobustAccess which reflects OpenGL naming better
    instead
-   @cpp Texture::maxLayers() @ce has misleading naming and is deprecated, use
    @ref Shader::maxCombinedTextureImageUnits() instead

@subsection changelog-2014-06-compatibility Potential compatibility breakages, removed APIs

        @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

-   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 @ref Texture::setMaxAnisotropy() "*Texture::setMaxAnisotropy()"
    in case @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 @ref 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
    @ref Magnum::Extensions)
-   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 @ref Buffer::data() 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 @ref CubeMapTextureArray::image() 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 @ref Texture::setWrapping() for rectangle
    textures
-   Fixed wrong assertion in @cpp AbstractImage::pixelSize() @ce when computing
    size of separate depth and stencil formats
-   @ref Mesh::addVertexBuffer() now properly computes offsets for matrix
    attributes
-   Taking index buffer offset into account in @ref MeshView 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 @ref BufferUsage enum instead
-   @cpp Mesh::Primitive @ce enum is deprecated to reduce header dependencies,
    use global @ref MeshPrimitive enum instead
-   @cpp Sampler::maxAnisotropy() @ce is deprecated to avoid naming conflict with
    @ref Texture::setMaxAnisotropy() "*Texture::setMaxAnisotropy()", use
    @ref Sampler::maxMaxAnisotropy() 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](http://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),

    [mosra/magnum#22](https://github.com/mosra/magnum/issues/22),
    [mosra/magnum#23](https://github.com/mosra/magnum/pull/23).

@subsection changelog-2013-10-new New features

-   Initial Emscripten (HTML5/WebGL) port. See @ref Platform::Sdl2Application
    for detailed porting information. The @ref example-index "examples page"
    has now links to online Emscripten demos, see also
    [base-emscripten](https://github.com/mosra/magnum-bootstrap/tree/base-emscripten)

    @ref Math::Matrix3x3 "Math::MatrixNxN<T>" template aliases for non-square
    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-info utility.
-   @ref Context::isExtensionSupported() is now able to query extension
    availability on particular GLSL version

    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 @ref Shapes::InvertedSphere "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

    @ref Containers::ArrayReference 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

@subsection changelog-2013-10-bugfixes Bug fixes

-   Fixed compilation with Clang and libc++ (see
    [mosra/magnum#12](https://github.com/mosra/magnum/issues/12))
-   Fixes compilation of the Audio library on macOS (see
    [mosra/magnum#19](https://github.com/mosra/magnum/issues/19))
-   Fixed compatibility of builtin shaders with GLSL 1.20 and GLSL ES 1.00,
    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))

    taking pair of data pointer and size are deprecated, use
    @cpp Containers::ArrayReference @ce-based @ref Buffer::setData() and
    @ref Buffer::setSubData()
-   `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
    @ref Platform::Sdl2Application::MouseMoveEvent::buttons() "Platform::*Application::*Event::buttons()"
    and @ref Platform::Sdl2Application::MouseMoveEvent::Button "Platform::*Application::*Event::Button"
    enum instead
-   @cpp AbstractShaderProgram::maxSupportedVertexAttributeCount() @ce,
    @cpp AbstractTexture::maxSupportedLayerCount() @ce and
