xz utils 5.2.0
for Win32 (there is also a new DOS version, for those interested)
Cygwin users should note that XZ Utils 5.2.x can lose data on Cygwin 1.7.34 or older. The bugs have been fixed in Cygwin 1.7.35 and thus XZ Utils 5.2.x works correctly on Cygwin 1.7.35 and later.
If you cannot upgrade to new enough Cygwin, you should stick to XZ Utils 5.0.x which is fine and safe to use on older Cygwin versions.
Old stable for Windows: 5.0.5.
Latest stable for Windows: 5.2.1 released on 2015FEB26.
I have not tested it yet.
This is for:
Intel Processor Identification Utility 5.10
Newer version of XZ, with additional notes.
TestDisk & PhotoRec 7.0 released (including versions for DOS and for Linux).
