• Zstd: Updated to 1.3.5 (up from 1.3.4)

Improvements

• Versioned classes in bindings now form inheritance hierarchies.
  • Applicable to the following versioned classes: AL, ALC, CL, EGL, GL, GLES, GLX, VK
  • For example, the GL30 class now extends the GL21 class, GL21 extends GL20 and so on.
  • With this change, importing a versioned class allows all symbols up to that version to be resolved. Earlier versions do not need to be imported separately.
• perf(core): memGetAddress/memPutAddress are now an order of magnitude faster on 32-bit JVMs.
• perf(core): Optimized pointer arithmetic by helping the JVM identify unsigned integers.
• perf(core): The new java.util.Objects index check intrinsics are used on Java 9.
• perf(core): MemoryUtil string decoding methods are now faster on both Java 8 and 9+.
  • The Java 9 implementations are tuned for compact strings (JEP 254).
• perf(generator): Function pointers in capabilities classes are not sorted by name anymore.
  • This makes it more likely that for functions that are commonly used together, their respective pointers
    will be closer in memory, avoiding unnecessary cache misses.
• Generator: org.lwjgl.system.JNI now includes signatures for known callback functions.
  • Can be used for callback function delegation.
• Generator: Added support for custom methods in struct classes.
• Generator: Added fluent setters for nested structs.
• Generator: Made StructBuffer subclass generation optional.
• Loader: Now prints the path of shared libraries loaded from system paths in debug mode, when possible.
• docs(core): Improved PointerBuffer javadoc.
• docs: The LWJGL javadoc is now generated with JDK 10.
• Core: MemoryUtil methods now replace requests for zero-size allocations with non-zero-size allocations.
  • A zero-size allocation now always returns a non-NULL pointer or throws an OOME. This is consistent with ByteBuffer.allocateDirect and avoids the undefined behavior of native allocators.
  • The returned buffer has a capacity of zero, regardless of the actual allocation size.
• Core MemoryUtil.memRealloc is not @Nullable anymore, will either succeed or throw an OOME, like memAlloc/memCalloc.
• Core: It is now possible to create a MemoryStack backed by externally managed memory.
• Core: The debug allocator now also tracks internal allocations of shared libraries that have been configured to use the LWJGL memory allocator.
  • This enables monitoring/debugging allocations inside shared libraries. Internal resources that are never released are now reported on shutdown.
  • Enabled by default when Configuration.DEBUG_MEMORY_ALLOCATOR is enabled.
  • May be disabled with Configuration.DEBUG_MEMORY_ALLOCATOR_INTERNAL.set(false).
• LMDB: The LWJGL memory allocator is now used for internal allocations.
• NanoVG/NanoSVG: The LWJGL memory allocator is now used for internal allocations.
• OpenGL/GLES: Calling an unavailable function triggers a JNI FatalError instead of an arbitrary segfault.
  • Avoids the intimidating crash log and writes a clean stack trace to stderr.

Fixes

• Generator: Fixed nullability of macro bindings.
• Generator: Fixed location of generated static blocks
• Core: Struct buffer malloc/calloc methods now support zero capacity, instead of throwing a NPE.
• macOS: Fixed version number detection in .dylib name mapping
• Nullability fixes in:
  • Assimp
  • CGL
  • Yoga
  • Parameters of struct multi-setter methods
• OpenCL: Fixed CL_DEVICE_PREFERRED_VECTOR_WIDTH_INT constant name.
• OpenCL: Dropped unnecessary clSetKernalArg3<t> overloads.
• OpenGL/GLES: The thread-local-free function pointer lookups do not depend on JVMTI anymore.
• stb: Fixed type of stbi_write_jpg function's data parameter.

Breaking Changes

• Core: MemoryUtil.MemoryAllocationReport now also returns the address of the memory allocation.
• NanoVG: Parameters windowWidth/windowHeight of the nvgBeginFrame function changed to float.

Known Issues

• vma: The native library is not initialized automatically.
  • Workaround: call Class.forName("org.lwjgl.util.vma.LibVma") before using the VMA bindings.
• vma: KHR_get_memory_requirements2 function addresses in VmaVulkanFunctions are not optional.
  • Workaround: Enable the KHR_get_memory_requirements2 extension, or set the equivalent function addresses from Vulkan 1.1.
