Changes since 3.2.0:


  • Added CUDA bindings.
    • Only the Driver API & NVRTC are supported in this release.
    • Bindings to more CUDA Toolkit libraries will be added in the future.
  • Added libdivide bindings.
  • Added LLVM/Clang bindings.
    • LLVM binaries are not included in this release. They must be separately downloaded or built for each platform.
  • Added Meow hash bindings.
  • Added Opus bindings.
  • bgfx: Updated to API version 90 (up from 76)
  • dyncall: Updated to 1.0 (up from 1.0-RC)
  • glfw: Updated to pre-release 3.3.0 version (up from 3.3.0 pre-release):
    • Added glfwAttachWin32Window. (experimental)
  • jemalloc: Updated to pre-release 5.2.0 (up from 5.1.0)
    • When available, it is again the default memory allocator on Windows.

  • OpenAL Soft: Updated to 1.19.1 (up from 1.18.2)
    • Added ALC_SOFT_device_clock extension.
  • OpenGL(ES): Added latest extensions:
    • NV_memory_attachment
    • NV_compute_shader_derivatives
    • NV_fragment_shader_barycentric
    • NV_mesh_shader
    • NV_representative_fragment_test
    • NV_scissor_exclusive
    • NV_shader_texture_footprint
    • NV_shading_rate_image
    • QCOM_shader_framebuffer_fetch_rate
    • QCOM_texture_foveated_subsampled_layout
  • OpenVR: Updated to 1.1.3b (up from 1.0.16)

  • Yoga: Updated to 1.10.0 (up from 1.9.0)
  • Zstd: Updated to 1.3.7 (up from 1.3.5)


  • perf(core): Refactored LWJGL internals to make call stacks shallower.
    • Makes it harder to cross Hotspot's default MaxInlineLevel threshold, which can disable important optimizations.
  • perf(core): Added memDuplicate and refactored memSlice with implementations that use Unsafe to construct buffer instances, similar to mem-X-Buffer.
    • Compared to the default JDK implementations, these methods are faster and enable Scalar Replacement via EA on Hotspot.
    • The memSlice with offset method is also thread-safe now.
  • perf(core): Implemented workarounds to make struct buffer iteration garbage free on Hotspot.
  • perf(core): Re-tuned string codecs and memCopy/memSet for Java versions 8 to 11.
  • perf(core): Added thread-local array cache to minimize allocations while decoding text.
  • bgfx: Builds of bgfx tools (geometryc, shaderc, texturec, texturev) are now available.
    • Use the file browser in the LWJGL website to download the executables.
    • For example, the latest Windows x64 build of shaderc can be found under nightly/windows/x64/bgfx-tools/.
  • vma: VmaVulkanFunctions.set(VkInstance, VkDevice) will now use Vulkan 1.1 functions instead of KHR_get_memory_requirements2 functions, if available.
  • Generator: The template DSL has been simplified considerably.
  • Generator: Added the LWJGL Template Extraction Tool. It uses the new Clang bindings to parse native headers and extract LWJGL template declarations.
    • Extracts both declarations and associated documentation.
    • Written in Kotlin. The source can be found in the extract module.


  • Core: Fixed text decoding from buffer with .position() > 0.
    • Affected all decoders on Java 9+, only UTF-16 on Java 8.
  • Core: Fixed the bounds check in memCopy. (#414)
  • OpenAL: Fixed signature of alListener3i. (#427)
  • OpenVR: The pGamePoseArray parameter of VRCompositor_WaitGetPoses is now nullable. (#418)
  • OpenVR: Fixed returned type of VRRenderModels_GetComponentStateForDevicePath.
  • OpenVR: Renamed VRInput_UncompressSkeletalActionData to VRInput_DecompressSkeletalBoneData.
  • OpenVR: Fixed wrong modifiers in VRInput functions:
    • VRInput_GetDigitalActionData
    • VRInput_GetAnalogActionData
    • VRInput_GetPoseActionData
    • VRInput_GetSkeletalActionData
    • VRInput_GetOriginTrackedDeviceInfo
  • vma: The native library is now initialized automatically.
  • vma: Optional KHR_get_memory_requirements2 addresses in VmaVulkanFunctions are now nullable.
  • vma: Nullability of VmaAllocationCreateInfo & VmaAllocationInfo members.

Breaking Changes

(B): binary incompatible change
(S): source incompatible change
  • Core: sun.misc.Unsafe is now required, there is no JNI fallback.
  • vma: The VmaVulkanFunctions.set helper method now returns VmaVulkanFunctions. (B)

Known Issues

  • Core: LWJGL 3.2.1 is incompatible with Java 12 or higher. (#491)
    • This issue is fixed in LWJGL 3.2.3.
