cFosSpeed 4.50 build 1456 -- 10-Feb-2009
+ Added new skin: "LC History"; it's like our well-known Liquid Crystal skin,
but with a history that scrolls to the left.
+ Added Layer-7 detection for large HTTP downloads (client & server).
HTTP transfers which take more than 1 sec. at full speed are now
classified as HTTP_C_BULK / HTTP_S_BULK and have low priority as
default. You can change the priority in the Layer-7 Protocol prioritization
dialog. Warning: This will only work, if the current HTTP connection
is not reused by the browser. Otherwise the first classification
will be used. The next version will remove this limitation.
+ Speeded memory allocation.
+ Improved detection of packets that NDIS sends erroneously to cFosSpeed.
x Added better handling of multiple but different SYN segments and improved
recovery after ACK for unsent data. Thanks to khashayar zayyani for help.
x Fixed a crash with Cisco Systems VPN Client. Thanks to Hardi Trenkel for
crash dump file.
x Adapters were sometimes unbound too fast, which caused Windows problems.
x It seems some networks trash the Ping IP packet when they return it to the
sender and cFosSpeed couln't find the replies in its lists. Thus, we
relaxed the check a bit. Thanks to Deepak for bug report.
x Tried to fix problem with socket error sending pings that caused ping
balloons. Thanks to yen linh for report.
x Fixed a bug where cFosSpeed would not properly reset the 'bridged'
setting when the router resets while cFosSpeed is running. Thanks to 4wd
for bug report and testing.
x Sometimes HTTP, SSL and SSH non-BULK l7-protocols would stay on default
priority even if the l7-protocol priority was set to high. Fixed. Thanks
to mumia for bug report.
x Fixed a crash under Vista that would close spd.exe. Thanks to SyntaX.
x Fixed x64 installer: now it pops up UAC dialog under Vista to make you full
Admin. This bug was introduced in build 1433.
x Fixed some Windows object security problems.
x L7 protocols SSL_C, SSL_S and SSH sometimes switched between _BULK and
regular versions periodically. This has been amended.
