 User visible changes for UPX
 ==================================================================
 
+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

+  * bug fixes
+
+Changes in 3.01 (31 Jul 2007):
+  * new options --no-mode, --no-owner and --no-time to disable preservation
+    of mode (file permissions), file ownership and timestamps.
+  * dos/exe: fixed an incorrect error message caused by a bug in
+    relocation handling
+  * new format linux/mipsel supports ELF on [32-bit] R3000
+  * fix argv[0] on PowerPC with --lzma
+  * bug fixes
+
+Changes in 3.00 (27 Apr 2007):
+  * watcom/le & tmt/adam: fixed a problem when using certain filters
+
+Changes in 2.93 beta (08 Mar 2007):
+  * new formats Mach/i386 and Mach/fat support Mac OS X i686 and
+    Universal binaries [i686 and PowerPC only]
+  * dos/exe: LZMA is now also supported for 16-bit dos/exe. Please note that
+    you have to explicitly use '--lzma' even for '--ultra-brute' here
+    because runtime decompression is about 30 times slower than NRV -

+unmapped, then the Linux kernel erases the symlink /proc/self/exe,
+and this can cause trouble for the runtime shared library loader
+expanding $ORIGIN in -rpath, or for application code that relies on
+/proc/self/exe.  Use the compress-time command-line option
+--unmap-all-pages to achieve that effect at run time.  Upx-3.04

+On arm*-linux-elf there is no good address at which to retain one

+0x8000 (32KiB) are rejected by the kernel.  Using a page above the
+original uncompressed brk(0) would require placing the entire initial
+compressed program above uncompressed brk(0), which would significantly
+increase the running brk(0); but too many programs break if brk(0)
+moves.  Thus on arm*-linux-elf the compressed executable begins
+with 0x8000==.p_vaddr, all pages mapped by execve() that are also
+occupied by decompressed bytes are removed before overwriting, and
+/proc/self/exe becomes a "(deleted)" symlink.  It might be possible
+to preserve /proc/self/exe if the original uncompressed executable
+were created with 0x9000==.p_vaddr (one page higher than the usual
+0x8000) so that the compressed page mapped at 0x8000 would linger.

-
-   If the caller did not specify anything,

-
-   REQUIRE_ORDER means don't recognize them as options;
-   stop option processing when the first non-option is seen.
-   This is what Unix does.
-   This mode of operation is selected by either setting the environment
-   variable POSIXLY_CORRECT, or using `+' as the first character
-   of the list of option characters.
-
-   PERMUTE is the default.  We permute the contents of ARGV as we scan,
-   so that eventually all the non-options are at the end.  This allows options
-   to be given in any order, even with programs that were not written to
-   expect this.
-
-   RETURN_IN_ORDER is an option available to programs that were written
-   to expect options and other ARGV-elements in any order and that care about
-   the ordering of the two.  We describe each non-option ARGV-element
-   as if it were the argument of an option with character code 1.
-   Using `-' as the first character of the list of option characters
-   selects this mode of operation.
-
-   The special argument `--' forces an end of option-scanning regardless
-   of the value of `ordering'.  In the case of RETURN_IN_ORDER, only
-   `--' can cause `getopt' to return EOF with `optind' != ARGC.  */

-/* Scan elements of ARGV (whose length is ARGC) for option characters
-   given in OPTSTRING.
-
-   If an element of ARGV starts with '-', and is not exactly "-" or "--",
-   then it is an option element.  The characters of this element
-   (aside from the initial '-') are option characters.  If `getopt'
-   is called repeatedly, it returns successively each of the option characters
-   from each of the option elements.
-
-   If `getopt' finds another option character, it returns that character,
-   updating `optind' and `nextchar' so that the next call to `getopt' can
-   resume the scan with the following option character or ARGV-element.
-
-   If there are no more option characters, `getopt' returns `EOF'.
-   Then `optind' is the index in ARGV of the first ARGV-element
-   that is not an option.  (The ARGV-elements have been permuted
-   so that those that are not options now come last.)
-
-   OPTSTRING is a string containing the legitimate option characters.
-   If an option character is seen that is not listed in OPTSTRING,
-   return BAD_OPTION after printing an error message.  If you set `opterr' to
-   zero, the error message is suppressed but we still return BAD_OPTION.
-
-   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
-   so the following text in the same ARGV-element, or the text of the following
-   ARGV-element, is returned in `optarg'.  Two colons mean an option that
-   wants an optional arg; if there is text in the current ARGV-element,
-   it is returned in `optarg', otherwise `optarg' is set to zero.
-
-   If OPTSTRING starts with `-' or `+', it requests different methods of
-   handling the non-option ARGV-elements.
-   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
-   Long-named options begin with `--' instead of `-'.
-   Their names may be abbreviated as long as the abbreviation is unique
-   or is an exact match for some defined option.  If they have an
-   argument, it follows the option name in the same ARGV-element, separated
-   from the option name by a `=', or else the in next ARGV-element.
-   When `getopt' finds a long-named option, it returns 0 if that option's
-   `flag' field is nonzero, the value of the option's `val' field
-   if the `flag' field is zero.
-
-   LONGOPTS is a vector of `struct option' terminated by an
-   element containing a name which is zero.
-
-   LONGIND returns the index in LONGOPT of the long-named option found.
-   It is only valid when a long-named option has been found by the most
-   recent call.
-
-   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
-   long-named options.  */
