 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.)

+On arm*-linux-elf there is no good address at which to retain one
+page of the compressed executable.  Pages below the usual .p_vaddr
+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.

 Linux stores the pathname argument that was specified to execve()
 immediately after the '\0' which terminates the character string of the
 last environment variable [as of execve()].  This is true for at least

-   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.  */

-   (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.  */

-
-   To have a long-named option do something other than set an `int' to
-   a compiled-in constant, such as set a value from `optarg', set the
-   option's `flag' field to zero and its `val' field to a nonzero
-   value (the equivalent single-letter option character, if there is
-   one).  For long options that have a zero `flag' field, `getopt'
