  We still can use __cpuid for low (func) values that don't require ECX,
  but __cpuid() in old MSVC will be incorrect for some func values: (func == 7).
  So here we use the hack for old MSVC to send (subFunction) in ECX register to cpuid instruction,
- where ECX value is first parameter for FASTCALL / NO_INLINE func,
+ where ECX value is first parameter for FASTCALL / NO_INLINE func.
  So the caller of MY_cpuidex_HACK() sets ECX as subFunction, and
  old MSVC for __cpuid() doesn't change ECX and cpuid instruction gets (subFunction) value.

+- The default dictionary size values for LZMA/LZMA2 compression methods were increased:

+   64 MB   64 MB  256 MB   -mx9 : Ultra
+  The default dictionary size values for 32-bit versions of LZMA/LZMA2 don't exceed 64 MB.
+- 7-Zip now can calculate the following hash checksums: SHA-512, SHA-384, SHA3-256 and MD5.
+- APM and HFS support was improved.
+- If an archive update operation uses a temporary archive folder and 
+  the archive is moved to the destination folder, 7-Zip shows the progress of moving 
+  the archive file, as this operation can take a long time if the archive is large.
+- The bug was fixed: 7-Zip File Manager didn't propagate Zone.Identifier stream
+  for extacted files from nested archives (if there is open archive inside another open archive).
+- Some bugs were fixed.
