  Big news
  * Frontend, druntime and Phobos are at version 2.094.1+, incl. new command-line options -cov=ctfe, -vtemplates=list-instances and -HC=<silent|verbose> . (#3560, #3582, #3588, #3593)
  * Support for LLVM 11. The prebuilt packages use v11.0.0; x86 packages newly include the LLVM backend for AMD GPUs. (#3546, #3586)
  * Experimental support for macOS on 64-bit ARM, thanks Guillaume! All druntime/Phobos unit tests pass. The macOS package includes prebuilt druntime/Phobos; adapt the SDK path in etc/ldc2.conf and then use -mtriple=arm64-apple-macos to cross-compile. If you know how to work around the countless linker warnings, please let us know. (dlang/druntime#3226, #3583)
  Platform support
  * Supports LLVM 6.0 - 11.0.
  Bug fixes
  * Fix potentially wrong context pointers when calling delegate literals. (#3553, #3554)
  * Fix alignment issue when casting vector rvalue to static array. (c8889a9)
  * Make sure lambdas in pragma(inline, true) functions are emitted into each referencing compilation unit. (#3570)
  * Fix -Xcc=-Wl,... by dropping support for comma-separated list of cc options. (c61b135)
  * Fix ThreadSanitizer support by not detaching main thread upon program termination. (#3572)
  * Traverse full chain of nested aggregates when resolving a nested variable. (#3556, #3558)
  Internals
  * CI: Linux AArch64 is now also tested by a Travis job, because Shippable has sadly become unreliable. (#3469)
  * Building LDC with an LDC host compiler might be somewhat faster now (requires -DLDC_LINK_MANUALLY=OFF in the CMake command-line on non-Windows hosts). (#3575)
  Known issues
  * When building LDC, old LDC 0.17.*/ltsmaster host compilers miscompile LDC ≥ 1.21, leading to potential segfaults of the built LDC. Ltsmaster can still be used to bootstrap a first compiler and then let that compiler compile itself. (#3354)
  * 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.

- Update to 1.22.0: 
  Big news
  * Frontend, druntime and Phobos are at version 2.092.1+.
    (#3413, #3416, #3429, #3434, #3452, #3467) (new)
  * AArch64: All known ABI issues have been fixed. C(++) interop should now be 
    on par with x86_64, and variadics usable with core.{vararg,stdc.stdarg}.
    (#3421)
  * Windows hosts: DMD's Visual C++ toolchain detection has been adopted. As
    that's orders of magnitude faster than the previous method involving the MS
    batch file, auto-detection has been enabled by default, so if you have a
    non-ancient Visual C++ installation, it will now be used automatically for
    linking. The environment setup has been reduced to the bare minimum
    (LIB and PATH). (#3415)
  * FreeBSD x64: CI with CirrusCI is now fully green and includes automated
    prebuilt package generation. The package depends on the llvm ports package
    and should currently work on FreeBSD 11-13. (#3453, #3464) (new)
  * Link-time overridable @weak functions are now emulated for Windows targets
    and work properly for ELF platforms. For ELF, LDC doesn't emit any COMDATs
    anymore. (#3424)
  * New ldc.gccbuiltins_{amdgcn,nvvm} for AMD GCN and NVIDIA PTX targets.
    (#3411)
  * druntime: Significant speed-up for core.math.ldexp. (#3440, #3446)
  Platform support
  * Supports LLVM 3.9 - 10.0.
  Bug fixes
  * Cross-module inlining (incl. pragma(inline, true)): Enable emission into
    multiple object files. This may have a significant impact on performance
    (incl. druntime/Phobos) when not using LTO. (#3126, #3442)
  * Android: Fix TLS initialization regression (introduced in v1.21) and
    potential alignment issues. Unfortunately, the ld.bfd linker is required
    for our custom TLS emulation scheme, unless you're willing to use a custom
    linker script. So -linker=bfd is the new default for Android targets.
    (#3462) (new)
  * Casting (static and dynamic) arrays to vectors now loads the data instead
    of splatting the first element. (#3418, #3419)
  * Fix return statements potentially accessing memory from destructed
    temporaries. (#3426)
  * Add proper support for -checkaction=halt. (#3430, #3431)
  * druntime: Include core.stdcpp.* modules. (#3103, #3158)
  * GCC-style asm: Add support for indirect input operands ("m"). (#3438)
  * FreeBSD: Fix backtraces for optimized code by switching to external
    libexecinfo. (#3108, #3453)
  * FreeBSD: Fix C math related issues (incl. CTFE math issues) by bringing
    core.stdc.{math,tgmath} up to speed. (dlang/druntime#3119)
  * Fix ICE for captured parameters not passed on the LLVM level. (#3441)
  * Convenience fixes for RISC-V and other exotic targets. (#3457, #3460) (new)
  Internals
  * When printing compile-time reals to hex strings (mangling, .di headers),
    LDC now uses LLVM instead of the host C runtime, for proper and consistent
    results. (#3410)
  * One limitation for exotic hosts wrt. C long double precision has been
    lifted. (#3414)
  * For AVR targets, the compiler now predefines AVR and emits all TLS globals 
    as regular __gshared ones. (#3420)
  * WebAssembly: New memory grow/size intrinsics. (ldc-developers/druntime#187) 
    (new)
  * New -fno-plt option to avoid PLT external calls. (#3443)
  * iOS/arm64 CI, running the debug druntime & Phobos unittests on an iPhone 
    6S. Thx Jacob for this tedious work! (#3379, #3450)
  Known issues
  * When building LDC, old LDC 0.17.*/ltsmaster host compilers miscompile LDC ≥ 
    1.21, leading to potential segfaults of the built LDC. Ltsmaster can still 
    be used to bootstrap a first compiler and then let that compiler compile 
    itself. (#3354)
  * 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.

- Update to 1.21.0:
  * Big news
    - Frontend, druntime and Phobos are at version 2.091.1+, incl. new CLI

  * Platform support
    - Supports LLVM 3.9 - 10.0.
  * Bug fixes
    - Fixed tail calls in thunks, affecting AArch64 (the debug libraries now work)
	  and possibly other architectures. (#3329, #3332)
    - Windows: Do not emit any column infos for CodeView by default
	  (like clang) & add -gcolumn-info. (#3102, #3388)
    - Windows: Do not leak MSVC-environment-setup into -run child processes.
	  A new LDC_VSDIR_FORCE environment variable can be used to enforce MSVC

  bootstrap version 0.17.6 
  See https://github.com/ldc-developers/ldc/issues/3109
- Disable -flto=4 option as llvm does not recognize this option

- Update to 1.16.0:
  * Big news
    - Frontend, druntime and Phobos are at version 2.086.1, incl. 
      a DIP1008 fix. (#3062, #3076, #3091) (new)

- Update to 1.15.0
  * Big news
    - Frontend, druntime and Phobos are at version 2.085.1, incl. new
	  command-line options -preview, -revert, -checkaction=context,
	  -verrors-context and -extern-std. (#3003, #3039, #3053) (new)
      + The Objective-C improvements from DMD 2.085 are not implemented
	    (#3007)
    - Support for LLVM 8.0. The prebuilt packages have been upgraded to
	  LLVM 8.0.0 and include the Khronos SPIRV-LLVM-Translator, so that
	  dcompute can now emit OpenCL too. (#3005)
    - Compiler memory requirements can now be reduced via the new -lowmem
	  switch, which enables the garbage collector for the front-end and
	  sacrifices compile times for less required memory. In some cases, the
	  overall max process memory can be reduced by more than 60%; see #2916
	  (comment) for some numbers. (#2916)
      + Note for package maintainers: this feature requires a recent D host
	    compiler (most notably, it doesn't work with ltsmaster), ideally
		LDC 1.15 itself due to important GC memory overhead improvements in
		2.085 druntime.
    - Support for generic @llvmAttr("name") parameter UDAs, incl. new
	  @restrict with C-like semantics. (#3043) (new)
    - macOS: 32-bit support was dropped in the sense of not being CI-tested
	  anymore and the prebuilt macOS package now containing x86_64 libraries
	  only. MACOSX_DEPLOYMENT_TARGET for the prebuilt package has been raised
	  from 10.8 to 10.9.
    - Prebuilt packages don't depend on libtinfo and libedit anymore. 
	  (#1827, #3019)
    - x86: SSSE3 isn't required for the prebuilt packages and generated
	  optimized binaries anymore. (#3045) (new)
  * Platform support
    - Supports LLVM 3.9 - 8.0.
  * Bug fixes
    - Implicit cross-module-inlining of functions annotated with
	  pragma(inline, true) without explicit -enable-cross-module-inlining has
	  been restored. (#2552, #3014)
    - Propagate well-known length of newly allocated dynamic arrays for
	  better optimizability. (#3041, #3042) (new)
    - JIT: Support implicit __chkstk calls for Windows targets, e.g., for
	  large stack allocations. (#3051) (new)
- Update so_version to 85
