* bug fixes, particularly better diagnosis of malformed input
* bug fixes - see https://github.com/upx/upx/milestone/4

Changes in 3.94 (12 May 2017):
* Add support for arm64-linux (aka "aarch64").
* Add support for --lzma compression on 64-bit PowerPC (Thierry Fauck).
* For Mach, "upx -d" will unpack a prefix of the file (and warn).
* Various improvements to the ELF formats.
* bug fixes - see https://github.com/upx/upx/milestone/3

Changes in 3.93 (29 Jan 2017):
* Fixed some win32/pe and win64/pe regressions introduced in 3.92
* bug fixes - see https://github.com/upx/upx/milestone/2

Changes in 3.92 (11 Dec 2016):
* INFO: 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.
* Support Apple MacOS 10.12 "Sierra", including more-robust de-compression.
* Explicitly diagnose Go-language bad PT_LOAD; recommend hemfix.c.
https://sourceforge.net/p/upx/bugs/195/ https://github.com/pwaller/goupx
* Fix CERT-FI Case 829767 UPX command line tools segfaults.
Received by UPX Team on 2015-May-08; originally reported
by Codenomicon to NCSC-FI on 2015-01-08.
The vulnerabilities were discovered by Joonas Kuorilehto and
Antti Häyrynen from Codenomicon.
* bug fixes - see https://github.com/upx/upx/milestone/1

Changes in 3.91 (30 Sep 2013):
* Added experimental support for Windows 64-bit PE files, based on
work by Stefan Widmann. Please use for testing only!
* bug fixes

=========

Changes in 3.09 (18 Feb 2013):
* New option --preserve-build-id for GNU ELF.
* Allow for code signing and LC_UUID on Mac OS X executables.
* Allow non-contiguous LC_SEGMENTs and 0==.vmsize for Mach-O.
* Allow zero-filled final page in PackUnix::canUnpack().
* bug fixes

Changes in 3.08 (12 Dec 2011):
* Fix allocation in runtime stub for darwin.macho-entry (i386 and amd64).
* Compress shared library on ELF i386 only [ld.so threatens even this case].
* Attempt to support ELF on QNX 6.3.0 for armel (experimental).
* Better diagnostic when ELF -fPIC is needed.
* PT_NOTE improvements for *BSD.
* Preserve more ELF .e_flags on ARM.
* Minor code improvements for ELF stubs.
* Defend against another flavor of corrupt PE header.
* bug fixes

Changes in 3.07 (08 Sep 2010):
* win32/pe: fixed relocation handling for files with *no* TLS callbacks
[severe bug introduced in 3.06]

Changes in 3.06 (04 Sep 2010):
* win32/pe: TLS callback support contributed by Stefan Widmann. Thanks!
* bug fixes

Changes in 3.05 (27 Apr 2010):
* i386-linux and amd64-linux support shared libraries (DT_INIT must
exist, all info needed by runtime loader must be first in .text, etc.)
* Linux /proc/self/exe now is preserved by default, by leaving behind
one page. New compress-time option --unmap-all-pages is available.
* Withdraw support for shared libraries on Darwin (Apple Mac OS X)
because upx does not understand enough about .dylib.
* bug fixes

Changes in 3.04 (27 Sep 2009):
* new format Mach/AMD64 supports 64-bit programs on Apple Macintosh.
* new formats Dylib/i386 and Dylib/ppc32 support shared libraries
[such as browser plugins] on Darwin (Apple Macintosh). An existing
-init function (LC_ROUTINES command) is required.
* new format vmlinuz/armel for Debian NSLU2 (etc.) linux kernel
* bvmlinuz boot protocol 2.08 for 386 Linux kernel
* Extended ABI version 4 for armel-eabi ARM Linux ELF
* bug fixes

Changes in 3.03 (27 Apr 2008):
* implement cache flushing for PowerPC (esp. model 440)
* fix cache flushing on MIPS (>3 MiB compressed, or with holes)
* fix MIPS big-endian
* bug fixes

Changes in 3.02 (16 Dec 2007):
* fix unmapping on arm-linux.elf
* fix error checking in mmap for i386-linux.elf [triggered by -fPIE]
* bug fixes
