- Fix bug (see issue #14) where some outbound TCP packets were never handled by the classify function and silently dropped. This can degrade outbound speed significantly, as it forces the Windows TCP/IP stack to re-send the missing data. Thanks to GhalemB who found the bug & fix.

- Refactor the WFP interface: * WinDivert sublayers are created and inserted when the driver is loaded. * All WinDivert callouts are installed at the same sublayer. - Clean-up the implementation of priorities. - Re-introduce deep copying for SNIFF mode. This avoids referencing the sniffed packets. - Fix-up the netfilter example: * Don't send RSTs to RST/FINs, this can start a RST war. * Don't inject ICMP outbound - this may not be a problem despite 1233 errors.

- Several changes to simplify the WinDivert Driver installation: 1) Remove the dependency on the WdfCoInstaller*.dll file. This file appears to be unnecessary for Windows 7 and up, and for patched Vista+2008. 2) Remove the WinDivert.inf file (only used by the co-installer). 3) 32/64-bit versions of the driver are now explicitly named, meaning that the two can co-exist in the same directory. 4) The 32-bit WinDivert.dll can now automatically load the 64-bit driver on 64-bit Windows. This means it is possible to write 32-bit WinDivert applications that automatically work on 64-bit windows. 5) WinDivert.dll now schedules the WinDivert service to be deleted right away. This should fix some cases where the service is never deleted, even during reboot. 6) Updated build scripts to reflect the changes.

- Simplify the WinDivert callout code: no longer handles multiple NET_BUFFERs in a single NET_BUFFER_LIST. Apparently this should only ever occur in the FORWARD layer in certain circumstances, and even then each fragment should be indicated individually anyway. This change removes a lot of needless complexity.

- WinDivert now queues copies of packets, rather than simply referencing the original packet. The former turns out to be problematic, since there is no guarantee that something else (e.g. another callout driver) modifies/overwrites the packet data whilst it is in the queue. Copying the data is not ideal either, but seems to be the only way to ensure the packet is not changed later.

- Towards WinDivert 1.1: * Re-brand "DIVERT" to "WINDIVERT" throughout the code-base. * New flags: > WINDIVERT_FLAG_PASSTHRU: Do not drop nor capture packets. Useful for injection-only handles. > WINDIVERT_FLAG_NO_CHECKSUM: Do not guarantee that diverted packets have a correct checksum. NOTE: Not yet tested! * New default values and limits for various WinDivert parameters, including WINDIVERT_PARAM_QUEUE_LEN, WINDIVERT_PARAM_QUEUE_TIME, and the maximum filter length. * New extended WinDivert functions that support asynchronous I/O: > WinDivertRecvEx(..) > WinDivertSendEx(..) NOTE: Not yet tested! * The WinDivert driver now services reads (receives) out-of-band. The motivation is because WFP callouts are run at DISPATCH_LEVEL, so we should not be doing expensive work in the ClassifyFn. This is also the same reason why the filter length has been restricted.

- Divert driver and library now fully support multi-threaded code. This includes making the driver handle I/O requests in parallel, and changing the library such that it uses overlapped I/O. Overall the package is now significantly faster. - The divert driver now only adds WFP callouts when a filter is set, instead of when a handle is created. - The divert driver now attempts to avoid adding WFP callouts that are superfluous with respect to the filter. - The divert driver now explicitly deletes filters and callouts during cleanup. This appears to resolve a bug where network connectivity is sometimes lost. - Added a new sample program: passthru.exe. This example doesn't do anything interesting but is useful for speed testing. - Rename build.sh to mingw-build.sh to avoid confusion.
