• The package-info javadoc in each module now also includes links to useful resources, such as:
  • The official API documentation.
  • The official source repository.
  • Guides, tutorials, SDKs, etc.

LWJGL no longer includes the following bindings:

• lwjgl-cuda
• lwjgl-libdivide
• lwjgl-meow
• lwjgl-nanovg: the Blendish and OUI bindings only
• lwjgl-openvr
• lwjgl-ovr
• lwjgl-sse
• lwjgl-tootle

Improvements

• Core: Added the Runtime Bindings Generator.
  • A preview API, in org.lwjgl.system.ffm, that allows users to define and use custom bindings.
  • Based on the Foreign Function & Memory (FFM) and ClassFile APIs (requires JDK 25 or later).
• Core: Added a new backend for downcalls, upcalls and off-heap memory access based on FFM.
  • Enabled by default on JDK 25 or later.
  • LWJGL is now fully functional with --sun-misc-unsafe-memory-access=deny.
  • See the FFM Guide for details.
• Core: Added memCopy support for Java arrays. (#972)
  • Array to buffer
  • Buffer to array
  • Corresponding unsafe overloads
• FreeBSD: LWJGL now requires FreeBSD 13.5 or later. (up from 13.3)
• Linux: x86_64 shared libraries are now built with GCC 15.1 (up from GCC 11.2)
  • The minimum GLIBC version is now 2.28. (up from 2.17)
• Linux: non-x86_64 shared libraries are now built with GCC 12.3 (up from GCC 11.4)
  • No change to minimum GLIBC version (2.35).
• Windows: Shared libraries are now built with Visual Studio 2026 (up from 2022)

Fixes

Breaking Changes

• Generator: Removed deprecated mallocStack/callocStack methods from structs.
• OpenCL: Fixed the carrier type of cl_ulong constants. (#1087)
  • Now mapped to long to avoid unintentional sign extension for negative values.
• Vulkan: MoltenVK on x64 now requires macOS 11.0 or later. (up from 10.13)
