  • Zstd: Updated to 1.3.7 (up from 1.3.5)

Improvements

  • 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.

Fixes

  • 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.
