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

+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
