LDC 1.40.0-beta4
Glad to announce the 4th beta for LDC 1.40. Major changes (since v1.39): * Based on D ~2.110.0 (today's upstream stable). * LLVM for prebuilt packages bumped to v18.1.8 (incl. macOS arm64). * Android: NDK for prebuilt package bumped from r26d to r27. * Emscripten: The compiler now mimicks a musl Linux platform wrt. extra predefined versions. ABI compatibility with clang improved too. * Mainly for **distro package maintainers**: Use system zlib instead of Phobos' vendored version through CMake `-DPHOBOS_SYSTEM_ZLIB=ON`. Thanks Andrei! * Edge-case fixes regarding IR struct layouts and link-time culling (for ELF targets).

Re: LDC 1.40.0-beta3
Oh, I forgot an item: * Emscripten: The compiler now mimicks a musl Linux platform wrt. extra predefined versions. This should pave the way for supporting Emscripten in druntime & Phobos (via `version(Emscripten)` special cases), which is probably much simpler with the musl libc interface than the WASI interface directly.

Please give this some extra regression testing if you find the
time, as it's the first LDC version with enforced opaque IR
pointers, and there might still be related, hard-to-find bugs
lurking in our codebase. You can e.g. run *optimized* unittests
via `DFLAGS=-O dub run -c unittest -b unittest`.

LDC 1.28.0-beta1
Glad to announce the first beta for LDC 1.28 - some highlights: * Based on D 2.098.0-beta.2+ (today's stable). * Dynamic casts across binary boundaries (DLLs etc.) now work. * Windows: `-dllimport=defaultLibsOnly` doesn't require `-linkonce-templates` anymore.

LDC 1.27.1
A new minor version was just released: * Based on D 2.097.2 (very few fixes over v1.27.0). * Improved `-ftime-trace` implementation for compiler profiling/tracing, now excluding LLVM-internal traces, adding frontend memory tracing, source file location infos etc. * An official prebuilt package for Linux AArch64 is available again.

Sorry, but it just demonstrates the capabilities of 2 seemingly totally unrelated rendering engines and might easily mislead beginners, not helping D at all. What makes you think the used programming language would have any effect on the capabilities of a rendering engine? Some old Quake engine was ported from C or C++ to Emscripten (JavaScript) via WebGL by Carmack himself IIRC some years ago, and the visual results were unsurprisingly identical. There might be differences in efficiency, especially for JavaScript vs. a system programming language, but most modern graphics are GPU-bound anyway.
