@ -99,6 +99,7 @@ GLFW bundles a number of dependencies in the `deps/` directory.
- [WGL] Removed `GLFW_USE_DWM_SWAP_INTERVAL` compile-time option
- [WGL] Bugfix: Swap interval was ignored when DWM was enabled
- [GLX] Added dependency on `libdl` on systems where it provides `dlopen`
- [GLX] Made all GLX functions dynamically loaded
- [GLX] Removed `_GLFW_HAS_GLXGETPROCADDRESS*` and `_GLFW_HAS_DLOPEN`
