UPX 3.92 released (Announce)

Just accidentaly I found that new version of executable packer was released in 11-Dec-16.
Whole project was moved into GitHub so new URL is https://upx.github.io/

It still has problem to compress FPC 3.0.x executables for DOS so I opened a issue into their bugtracer.

UPX 3.92 released - found a bug!

I just found a bug in new UPX 3.92.
When I compressed the library MFC120.DLL (regardless of used compression level or executable version dos/win32) the result was that application which use this library failed to load with initialization error 0xc0000005. If the library is decomressed and repacked by previous UPX 3.91 (regardless of used compression level or executable version dos/win32) it always works fine.
So be carefull and keep the old version handy!

UPDATE: and it's not the only one, IDRVDLL.DLL, Idrvdll32e.dll from intel BIOS tools also gets crippled so the bug may affect much more Win32 PE files!

This is expected. See the changelog:

Changes in 3.92 (11 Dec 2016):
* UPX has moved to GitHub - the new home page is https://upx.github.io
* IMPORTANT: all PE formats: internal changes: reunited the diverged source files - please report all regressions into the bug tracker and try UPX 3.91 in case of problems.
