 User visible changes for UPX
 ==================================================================
 
-[ UNSTABLE BETA VERSION - please see README.1ST for some more info ]
+Changes in 2.90 (08 Oct 2006):
+  * LZMA algorithm support for most of the 32-bit and 64-bit file formats;
+    use new option '--lzma' to enable
+  * new format: BSD/elf386 supporting FreeBSD, NetBSD and OpenBSD
+    via auto-detection of PT_NOTE or EI_OSABI
+  * arm/pe: all the NRV compression methods are now supported
+    (only NRV2D is missing in thumb mode)
+  * linux/elf386, linux/ElfAMD remember /proc/self/exe in environment
+  * vmlinuz/386: fixed zlib uncompression problem on dos
+  * major source code change: the runtime decompression stubs are now
+    built from internal ELF objects
+
+Changes in 2.02 (13 Aug 2006):
+  * linux/386: work around Linux kernel bug (".bss" requires PF_W)
+  * linux/ppc32, mach/ppc32: compressed programs now work on a 405 CPU
+  * vmlinuz/386: fixed zlib uncompression problem on dos
+
+Changes in 2.01 (06 Jun 2006):
+  * arm/pe: better DLL support
+  * dos/exe: device driver support added
+  * linux/386: Fix --force-execve for PaX, grSecurity, and strict SELinux.
+    /tmp must support execve(); therefore /tmp cannot be mounted 'noexec'.
+  * win32/pe & arm/pe: added new option '--keep-resource=' for
+    excluding selected resources from compression
+
+Changes in 2.00 (27 Apr 2006):
+  * linux/386: the stub now prints an error message if some strict
+    SELinux mode does prevent runtime decompression and execution
+    (for a fully SELinux-compatible but otherwise inferior compression
+    format you can use the '--force-execve' option)
+  * linux/386: worked around a problem where certain Linux kernels
+    clobber the %ebx register during a syscall
+  * win32/pe: disable filters for files with broken PE headers
+
+Changes in 1.96 beta (13 Apr 2006):
+  * arm/pe: added filter support
+  * win32/pe: removed an unnecessary check so that Delphi 2006 and

+  * arm/pe: added thumb mode stub support
+  * arm/pe: added unpacking support
+  * win32/pe: really worked around R6002 runtime errors
+
+Changes in 1.94 beta (11 Mar 2006):

+  * new format: added support for linux elf/amd64
+  * new format: added support for linux elf/ppc32
+  * new format: added support for mach/ppc32 (Apple Mac OS X)

-   will NOT be recognized (but you can use a macro called `jmps' for it

- - at the end of the file you need something like this

-            section .data

+                        UPX and SELinux
+                        March 6, 2006
+
+
+When a program that has been compressed by UPX is run, the decompressor
+must create and write new memory pages of executable instructions.
+SELinux (Security Enhanced Linux) directly controls the conditions
+under which generating and/or executing new instructions is allowed,
+so the configuration settings of SELinux affect the running of programs
+that have been compressed by UPX.
+
+In SELinux "strict enforcing" mode (the most restrictive), generating
+new instructions at runtime is not allowed at all: any page with
+PROT_EXEC permission must be mapped from a file in a mounted filesystem
+that has 'x' [eXecute] permission, and the generation of such files is
+also tightly controlled.  A program that was compressed by UPX will not
+run in SELinux strict enforcing mode.  Attempts will fail with exit
+code 127, and a record will be added to the history file
+/var/log/audit/audit.log.
+
+In "targeted enforcing" mode, SELinux pays close attention mostly to
+designated processes that run with elevated privileges: web server,
+print server, login server, etc.  Ordinary user excutables receive
+much less scrutiny.  However, one of the eventual goals of SELinux is to
+eradicate runtime generation of instructions because of the possibility
+for exploitation by malware (virus, trojan, key logger, privilege
+elevation exploit, etc.)  Thus targeted enforcing mode notices and
+logs the use of "execmem" capability that is used by a program which
+was compressed by UPX.  In keeping with the goal of eventual prohibition,
+SELinux ordinarily would deny execmem.  However, most current SELinux
+systems, including Fedora Core 5 [set for release March 15, 2006],
+override this with "allow_exemem=1" in /etc/selinux/targeted/booleans.
+Thus a program compressed by UPX will run in the default installed
+configuration (targeted enforcing, allow_execmem=1) of SELinux under
+Fedora Core 5.  Each invocation will add a few lines to the log file
+/var/log/audit/audit.log, one line for each use of execmem.  If the
+SELinux policy becomes more restrictive in the future, then a special
+SELinux class or other mechanism must be created for compressed programs,
+or else UPX-compressed executables will not run then.
+
+In its "permissive" modes, SELinux just logs the potential problems,
+but otherwise does not interfere.  A program compressed by UPX will run
+in any permissive mode.

-The GNU bfd binary file descriptor package, part of the GNU binutils package,
-contains code to recognize an Elf file by looking at fields in the file header.
-Many programs (such as gdb, size, objdump, objcopy, strip and others) use bfd.
-Unfortunately, bfd has been overly strict.  In releases
-   binutils-2.9.1.0.4, binutils-2.9.1.0.23, binutils-2.9.5.0.0,
-   binutils-2.10.1,
-   gdb-4.17, gdb-5.0,
-and probably others,
-bfd does not recognize a file with zero in Elf32_Ehdr.e_shoff, .e_shentsize,
-or .e_shnum, even though the operating system kernel does not care, and many
-bfd clients would work just fine in these cases.
-
-Because of its desire to create small size compressed executables, UPX
-generates and uses Elf files with zero in .e_shoff, .e_shentsizes, and .e_shnum.
-As a result, many widely-distributed instances of gdb, size, objdump, etc.,
-refuse to work on UPX-packed executables.
-
-Here is a patch to bfd/elfcode.h which enables many bfd clients to work
-with UPX-packed executables.  The last two lines of the patch are
