The 'powerpcspe' architecture is a binary-incompatible variant of
PowerPC/POWER designed and supported by FreeScale and IBM. It is also
known under the trade names "e500"/"MPC8500" and "e200"/"MPC5xx".
Additional information can be found at:
http://en.wikipedia.org/wiki/PowerPC_e500
http://en.wikipedia.org/wiki/PowerPC_e200
In particular, the 'powerpcspe' architecture lacks the classic FPU with
dedicated FPRs found on most other PowerPC systems. It is replaced with
a set of "SPE" instructions which perform floating-point operations on
the integer registers.
In an unfortunate choice of architecture design, the instructions used
for the "SPE" operations overlap with those for the AltiVec unit on most
other modern PowerPC cores.
The "e500v2"-series chips have 64-bit GPRs, where the high 32-bits are
accesible only via the special "SPE" instructions, allowing them to make
efficient use of the "double" datatype.
The relative rare "e500v1"-series chips have only 32-bit GPRs, and
require software traps and emulation to support native "double".
The "e200z3" and "e200z6" chips have no support for floating point at
all, but with software traps and emulation are binary-compatible with
the "e500"-series chips.
The Debian port to this architecture specifically chooses to optimize
for the higher-end chips (e500v2), as most of the others are targeted
at automotive applications or no longer in production.
The specific GNU triplet for this arch is "powerpc-linux-gnuspe". As a
result, we end up adding an extra "ostable" entry instead of one in
"cputable".

The "Flatulent Elm of West Ruislip" Release.
* Actions and package states are now logged by default in the
/var/log/dpkg.log file. This file is rotated monthly and can be
disabled by commenting the line in /etc/dpkg/dpkg.cfg.
* User decisions about conffiles are now logged.
* dpkg-source no longer complains about Enhances field. Closes: #159642,
#159745, #159746.
* preinst no longer relies on procps being installed. Closes: #311808.
* Architecture Support:
- Change DEB_*_GNU_CPU from i386 to i486, to reflect reality.
DEB_*_ARCH_CPU remains at i386, you should be checking against that.
Closes: #310394.
- Fixed order ostable is read to prevent Linux becoming the Hurd.
Closes: #309603.
* Updated Manpage Translations (Christian Perrier):
- Syntax error corrected in Swedish man page for dpkg-deb.
Closes: #300980.
- Syntax error corrected in Spanish man page for dpkg-scanpackages.
Closes: #300981

* md5sum has been removed, the coreutils or textutils version will be
diverted to /usr/bin/md5sum. Closes: #6633, #136110.
The following bugs are filed against the dpkg md5sum, so no longer apply.
Closes: #95755, #193877, #223381, #264195, #270241, #286632,
* Take Replaces into account when installing packages; don't issue a
"trying to overwrite" error if the file that already exists is in
a package that Replaces the one being installed.
Closes: #164595, #184635, #277890.
* Allow actions and status changes to be logged to a file. Disabled by
default, uncomment line in /etc/dpkg/dpkg.cfg to enable.
Closes: #957, #53376, #77109, #143882, #284499.
* Don't truncate output of 'dpkg -l' when stdout is not a tty.
Closes: #92263, #253860, #258608, #261822, #282790.
* Fix further compilation problems with gcc 4.0. Closes: #299699
* Handle tar files without trailing slash in directory names.
Closes: #287152.
* Output arguments to maintainer scripts with -D2. Closes: #237684,
#296030.
* Architecture Support:
- Added ppc64. Closes: #263743.
- Split archtable into cputable and ostable, archtable is retained
for compatibility with other packages that might use it only.
- dpkg-architecture no longer canonises -t argument. Closes: #173205.
- dpkg-architecture output includes new DEB_*_ARCH_OS and
DEB_*_ARCH_CPU variables that contain the Debian system and CPU
names respectively.
- dpkg-architecture outputs (mostly) correct GNU system names now,
in particular this means that it will output "linux-gnu" instead
of "linux". You should use the new _ARCH_OS variables instead.
* Documentation:
- Add examples to dpkg-divert(8). Closes: #291816.
- Correct typo in dpkg-architecture(1). Closes: #299090.
