@subsection changelog-latest-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
-   @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 `"No errors."` 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
-   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)

@subsubsection changelog-latest-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-latest-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-latest-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

-   Continuous testing for Linux, macOS, Windows MSVC, Windows MinGW, Windows RT,
    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 [coveralls.io](https://coveralls.io/github/mosra/magnum);
    replacing the unmaintained and outdated Jenkins configuration
-   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.
-   Reworked CMake buildsystem to use the new imported target workflow, see
    @ref cmake for more information
-   CMake targets are now organized in folders for better development
    experience in IDEs such as Visual Studio or Xcode
-   Added @ref building-packages-brew "Homebrew package"
-   Improvements and dependency updates to the
    @ref building-packages-deb "Debian package"

    @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.
-   `MACOSX_RPATH` is now enabled by default on CMake 3.0+
-   Enabling only C++ in CMake @cmake project() @ce call, if possible, to speed
    up initial CMake run

    @ref cmake "CMake option"
-   Fixed `FindSDL2.cmake` module to work out-of-the-box on Windows and macOS
-   Bundling a patched version of `FindOpenAL.cmake` to make it working on
    Emscripten

-   `AbstractShaderProgram::setUniform(Int, UnsignedInt, const T*)` is
    deprecated, use @ref AbstractShaderProgram::setUniform(Int, Containers::ArrayView<const Float>) "AbstractShaderProgram::setUniform(Int, Containers::ArrayView<const T>)"
    instead
-   `Magnum/ImageReference.h` header and `ImageReference` type is deprecated,

    @ref Corrade::Containers::ArrayView instead
-   Templated @ref Buffer::data(), @ref Buffer::subData() and
    @ref Buffer::map() are deprecated, use the non-templated versions in
    combination with @ref Corrade::Containers::arrayCast() instead
-   @ref Context::current() and @ref Audio::Context::current() returning a
    pointer is deprecated, it's returning a reference now and asserts that a
    context exists. Use @ref Context::hasCurrent() and @ref Audio::Context::hasCurrent()
    to check for context presence.
-   Angle literals available directly in the @ref Magnum namespace are
    deprecated, import the @ref Math::Literals namespace instead
-   `Platform::Sdl2Application::MouseEvent::Button::WheelUp`,
    `Platform::Sdl2Application::MouseEvent::Button::WheelDown`,

    @ref Platform::GlfwApplication::MouseScrollEvent instead
-   @ref Platform::Sdl2Application::Sdl2Application() "Platform::*Application::*Application()"
    and @ref Platform::WindowlessGlxApplication::WindowlessGlxApplication() "Platform::Windowless*Application::Windowless*Application()"
    constructors taking @cpp nullptr @ce are deprecated, use constructors
    taking @ref NoCreateT instead to create an application without creating
    OpenGL context
-   `Math::Color*::fromHSV()` and `Math::Color*::toHSV()` are deprecated, use
    @ref Math::Color3::fromHsv() "Math::Color*::fromHsv()" and
    @ref Math::Color3::toHsv() "Math::Color*::toHsv()" instead
-   `Math::normalize()` and `Math::denormalize()` had confusing naming and thus
    are deprecated, use @ref Math::pack() and @ref Math::unpack() from the
    @ref Magnum/Math/Packing.h header instead
-   @ref Trade::MeshData2D and @ref Trade::MeshData3D constructors without the
    `colors` parameter are deprecated, use the full ones instead
-   @ref Shaders::Generic::Color vertex attribute implicit constructor is
    deprecated, use a constructor with explicit component count instead
-   The bundled `std::optional` implementation was causing serious conflicts
    with C++17 and it's now deprecated in favor of @ref Containers::Optional.
    (Deprecated) aliases and conversion operators are provided for backwards
    compatibility.

@subsection changelog-latest-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.

@subsection changelog-latest-performance Performance improvements

-   Reduced size of and number of allocations in @ref Mesh class.

@subsection changelog-latest-docs Documentation

-   New documentation theme powered by [m.css](http://mcss.mosra.cz) and
    related massive updates of *everything*
-   Explicit list of extensions that are available in WebGL builds
-   New page explaining @ref opengl-wrapping "OpenGL wrapper layer"
-   Documented extra CMake modules in @ref cmake-modules
-   The @ref building documentation now prefers package installation instead of
    manual build
-   Documented how to use Vcpkg packages
