Glad to announce the second beta for LDC 1.27. Some noteworthy
changes since beta1:
* Frontend and druntime/Phobos upgraded to yesterday's DMD
stable.
* Windows DLL support: some fixes/tweaks and a new -dllimport
option for greater flexibility.
* Prebuilt Linux and Mac packages can show significant compiler
performance increases due to newly employing the mimalloc
allocator.
* Important fixes for -linkonce-templates, DWARF v5 (e.g. with
linked-in C[++] parts compiled with gcc 11) and bundled dub
supporting somewhat longer paths on Windows.

Please help test, and thanks to all contributors & sponsors!
undefined symbol __fieldPostblit and __postblit cause link error
only with LTO enabled for windows mingw target.
There is more undefined symbols for LDC 1.27 compare to 1.26. My
code not changed and they used to work with old version ldc.
without LTO all work fine, old LDC link with -flto and -O fix the
missing symbol, but 1.26 && 1.27 not work anymore.
