完整更新日志（英文）

Frontend, druntime and Phobos are at version 2.084.1, incl. new command-line options -mixin , -{enable,disable}-switch-errors and -checkaction . (#2946, #2977, #2999) (new)
- Options -release , -d-debug and -unittest don't override preceding, more specific options ( -{enable,disable}-{asserts,invariants,preconditions,postconditions,contracts} ) anymore.
Linking WebAssembly doesn't require -link-internally (integrated LLD) anymore; an external linker (default: wasm-ld , override with -linker ) can be used as well. (#2951)
Prebuilt Windows packages include LTO-able 32-bit druntime/Phobos too (previously: Win64 only).
AddressSanitizer support for fibers (requires rebuilding the runtime libraries with CMake option RT_SUPPORT_SANITIZERS=ON ). (#2975, ldc-developers/druntime#152) (new)
Support pragma(LDC_extern_weak) for function declarations - if the function isn't available when linking, its address is null. (#2984) (new)

Fix C++ mangling regression for functions with multiple real parameters introduced with v1.13, preventing to build DMD. (#2954, dlang/dmd#9129)
Fix context of some nested aggregates. (#2960, #2969)
Support templated LLVM intrinsics with vector arguments. (#2962, #2971)
Avoid crashes with -allinst (fix emission of only speculatively nested functions). (#2932, #2940)
Fix XRay support for LLVM 7+. (#2965)
AArch64: Fix DMD-style profile measurements. (#2950)
Be less picky about placement of pragmas (allow intermediate extern(C) etc.). (#2599)
MSVC: Fix real C++ mangling to match Visual C++ long double . (#2974)
Fix bad ICE noticed when building protobuf-d. (#2990, #2992) (new)
Fix ICE when directly indexing vector return value. (#2988, #2991) (new)
Fix identity comparisons of complex numbers. (#2918, #2993) (new)
MIPS32 fix for core.stdc.stdarg . (#2989, ldc-developers/druntime#153) (new)
Fix core.atomic.cas() for 64-bit floating-point values. (#3000, #3001) (new)
beta1 regression: 'Instruction does not dominate all uses' (#2996, #2997) (new)

Buggy older ld.bfd linker versions may wrongly strip out required symbols, e.g., ModuleInfos (so that e.g. no module ctors/dtors are run). LDC defaults to ld.gold on Linux.
LDC does not zero the padding area of a real variable. This may lead to wrong results if the padding area is also considered. See #770. Does not apply to real members inside structs etc.
