================================================================== User visible changes for UPX ================================================================== 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 - which is really noticeable on old machines. * dos/exe: fixed a rarely occuring bug in relocation handling * win32/pe & arm/pe: better icon compression handling Changes in 2.92 beta (23 Jan 2007): * new option '--ultra-brute' which tries even more variants * slightly improved compression ratio for some files when using '--brute' or '--ultra-brute' * bug fixes Changes in 2.91 beta (29 Nov 2006): * assorted bug fixes * arm/pe: fix "missing" icon & version info resource problem for wince 5 * win32/pe & arm/pe: added option --compress-icons=3 to compress all icons Changes in 2.90 beta (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 * major source code changes: the runtime decompression stubs are now built from internal ELF objects ================================================================== Changes in 2.03 (07 Nov 2006): * bvmlinuz/386: fix for kernels not at 0x100000; also allow x86_64 * linux/elf386: work around Linux kernel bug (0-length .bss needs PF_W) 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 Reproducible: Always Steps to Reproduce:
Also note that the upstream developers have now changed to .tar.bz2

Bleh.
Imho it's useless to have 2 versions of upx in portage. app-arch/upx-ucl is compiled by source, app-arch/upx uses binary.
there's a difference i believe: * source code (you also need UCL) * UPX uses the NRV compression library for compression services. A compatible but somewhat less efficient OpenSource implementation is available through the UCL compression library. I'd take it to say the source code doesn't use the NRV compression library where as the binary does.
in cvs. thanks.
