## New features {#features}

### Multiple window contexts {#multiple_window_contexts}

GLFW now provides the ability to create multiple OpenGL and OpenGL ES
contexts for a given window. Called user contexts, a [GLFWusercontext](@ref context_user)
can be created using @ref glfwCreateUserContext,
destroyed using @ref glfwDestroyUserContext, and managed with
@ref glfwMakeUserContextCurrent and @ref glfwGetCurrentUserContext.
For more information see the [user context](@ref context_user) documentation.

### Unlimited mouse buttons {#unlimited_mouse_buttons}

GLFW now has an input mode which allows an unlimited number of mouse buttons to
be reported by the mouse buttton callback, rather than just the associated
[mouse button tokens](@ref buttons). This allows using mouse buttons with
values over 8. For compatibility with older versions, the
@ref GLFW_UNLIMITED_MOUSE_BUTTONS input mode needs to be set to make use of
this.
