## Asking a question
Questions about how to use GLFW should be asked either in the [support
section](http://discourse.glfw.org/c/support) of the forum, under the [Stack
Overflow tag](https://stackoverflow.com/questions/tagged/glfw) or [Game
Development tag](https://gamedev.stackexchange.com/questions/tagged/glfw) on
Stack Exchange or in the IRC channel `#glfw` on
[Freenode](http://freenode.net/).
Questions about the design or implementation of GLFW or about future plans
should be asked in the [dev section](http://discourse.glfw.org/c/dev) of the
forum or in the IRC channel. Please don't open a GitHub issue to discuss design
questions without first checking with a maintainer.

it already has everything, give it a :+1:.

## Requesting a feature
Please explain why you need the feature and how you intend to use it. If you
have a specific API design in mind, please add that as well. If you have or are
planning to write code for the feature, see the section below.
If there already is a request for the feature you need, add your specific use
case unless it is already mentioned. If it is, give it a :+1:.
## Contributing a bug fix ## Contributing a bug fix
There should be text here, but there isn't. __Note:__ You must have all necessary [intellectual
property rights](https://en.wikipedia.org/wiki/Intellectual_property) to any
code you contribute. If you did not write the code yourself, you must explain
where it came from and under what license you received it. Even code using the
same license as GLFW may not be copied without attribution.
__There is no preferred patch size__. A one character fix is just as welcome as
a thousand line one, if that is the appropriate size for the fix.
In addition to the code, a complete bug fix includes:
- Change log entry in `README.md`, describing the incorrect behavior
- Credits entries for all authors of the bug fix
Bug fixes will not be rejected because they don't include all the above parts,
but please keep in mind that maintainer time is finite and that there are many
other bugs and features to work on.
If the patch fixes a bug introduced after the last release, it should not get
a change log entry.
## Contributing a feature ## Contributing a feature
This is not (yet) the text you are looking for. __Note:__ You must have all necessary rights to any code you contribute. If you
did not write the code yourself, you must explain where it came from and under
what license. Even code using the same license as GLFW may not be copied
without attribution.
__There is no preferred patch size__. A one character change is just as welcome
as one adding a thousand line one, if that is the appropriate size for the
feature.
In addition to the code, a complete feature includes:
- Change log entry in `README.md`, listing all new symbols
- News page entry, briefly describing the feature
- Guide documentation, with minimal examples, in the relevant guide
- Reference documentation, with all applicable tags
- Cross-references and mentions in appropriate places
- Credits entries for all authors of the feature
If the feature requires platform-specific code, at minimum stubs must be added
for the new platform function to all supported and experimental platforms.
If it adds a new callback, support for it must be added to `tests/event.c`.
If it adds a new monitor property, support for it must be added to
`tests/monitor.c`.
If it adds a new OpenGL, OpenGL ES or Vulkan option or extension, support
for it must be added to `tests/glfwinfo.c` and the behavior of the library when
the extension is missing documented in `docs/compat.dox`.
Features will not be rejected because they don't include all the above parts,
but please keep in mind that maintainer time is finite and that there are many
other features and bugs to work on.
Please also keep in mind that any part of the public API that has been included
in a release cannot be changed until the next _major_ version. Features can be
added and existing parts can sometimes be overloaded (in the general sense of
doing more things, not in the C++ sense), but code written to the API of one
minor release should both compile and run on subsequent minor releases.

information on what to include when reporting a bug.
## Changelog ## Changelog
- Bugfix: The range checks for `glfwSetCursorPos` used the wrong minimum - Added on-demand loading of Vulkan and context creation API libraries
- Added `_GLFW_VULKAN_STATIC` build macro to make the library use the Vulkan
loader linked statically into the application (#820)
- Bugfix: Single compilation unit builds failed due to naming conflicts (#783)
- Bugfix: The range checks for `glfwSetCursorPos` used the wrong minimum (#773)
- Bugfix: Defining `GLFW_INCLUDE_VULKAN` when compiling the library did not
fail with the expected error message (#823)
- Bugfix: Inherited value of `CMAKE_MODULE_PATH` was clobbered (#822)
- [Win32] Bugfix: `glfwSetClipboardString` created an unnecessary intermediate
copy of the string
- [Win32] Bugfix: Examples failed to build on Visual C++ 2010 due to C99 in
`linmath.h` (#785)
- [Win32] Bugfix: The first shown window ignored the `GLFW_MAXIMIZED` hint
when the process was provided a `STARTUPINFO` (#780)
- [Cocoa] Bugfix: Event processing would segfault on some machines due to
a previous distributed notification listener not being fully
removed (#817,#826)
- [Cocoa] Bugfix: Some include statements were duplicated (#838)
- [X11] Bugfix: Window size limits were ignored if the minimum or maximum size
was set to `GLFW_DONT_CARE` (#805)
- [X11] Bugfix: Input focus was set before window was visible, causing
`BadMatch` on some non-reparenting WMs (#789,#798)
- [X11] Bugfix: `glfwGetWindowPos` and `glfwSetWindowPos` operated on the
window frame instead of the client area (#800)
- [WGL] Added reporting of errors from `WGL_ARB_create_context` extension
- [GLX] Bugfix: Dynamically loaded entry points were not verified
- [EGL] Added `lib` prefix matching between EGL and OpenGL ES library binaries
- [EGL] Bugfix: Dynamically loaded entry points were not verified
