cFosSpeed 8.00 build 1946 -- 07-May-2012

! cFosSpeed will now automatically expand Windows' TCP RWIN as needed!
With our new "Automatic RWIN expansion" cFosSpeed will expand the RWIN (and
the matching window scaling) to a value that allows a download with full
speed and a delay of 100 msec.
This makes system-wide settings of "GlobalMaxTcpWindowSize" or
"TcpWindowSize" (under XP) superfluous and will keep your downloads fast even
if Windows 7 "auto-tuning" feature doesn't work for you.
As an added goodie it will provide fast download even for programs that
can not achieve full download speed because they provide too small buffers to
the Windows TCP/IP interface, like Cygwin SCP.
You can change the maximum delay (i.e. TCP round trip time), but that affects
memory consumption: cFosSpeed needs (delay in seconds) * (downloadspeed in
bytes/sec) bytes, i.e. for a DSL line with 25 mbits/s (about 3000 kbytes/s)
the memory requirement is 0.1 sec * 3000000 bytes/sec = 300 kbytes. To
change this time use the "spd gset expand_rwin_dest_time "
command.

* Added WMI support. cFosSpeed creates a WMI class 'cfosspeed_perf_data'
in the namespace \root\cfos which has all known skin variables as
properties (see www.cfos.de/en/skin/skin-reference.htm for details).
This allows WMI utilities to display the same information as in the
cFosSpeed status window. There is a little demo of how to access the
cFosSpeed WMI data: wmi_demo.hta in the cFosSpeed dialog folder.

* To help cFosSpeed work with mobile connections it now dynamically tries ping
TTL values until someone answers, max with TTL 24. This should help some
users, where the first 10 or so hops would not answer.

+ Skin section now have an optional parameter 'print_allowed'. You can set
it to 0 to disable this section when not rendered as normal window on
screen.

+ Added Slovenian language. That makes a total of 33 languages supported.
Even more languages are downloadable from our web site, here:
http://www.cfos.de/speed/documentation/lang.htm

+ cFosSpeed now checks every 2 days for program news. If there are any,
it displays the mail symbol in the status window and opens a url when
clicked. This feature is on by default. If you are not interested in
program news, you can turn it off in the context menu under "Options".

x Fixed a bug with negation of -s-iplist, -d-iplist, -r-iplist, -l-iplist
rules. Thanks to Oliver Niebur for the report.

x Added work-around for a Windows XP bug which prevented opening of web
sites.

x Fixed a bug in the XL skins, where Mbytes per seconds were not displayed
correctly. Thanks to Cody.

x cFosSpeed now installs on Windows 8 Consumer Preview. Thanks for all
feedback!

x Fixed a bug which prevented connections to be displayed by the keyboard
LED script. Thanks to yashpalshah for the report.

x On some machines spd.exe consumed a lot of CPU power and accessed the
registry heavily. Fixed. Thanks to Empyter.

x On some machines the status window is not always displayed after sleep.
Fixed.

x The on-the-fly prioritization dialog did not allow you to permanently
prioritise programs, which weren't already permanently prioritised.
Fixed.

- Integrated keyboard LED support into cFosSpeed.exe. It no longer uses
the scripting host.
- Program news will not be displayed immediately after first installation.
- Changed COM initialisation.
- Improved setupapi log file support.
- Added memory debugging.
- OEM versions no longer notify the user about updates.
