Fix8 version 0.8.0 released

This is a big release. Here are the highlights:


1. Performance: 2x faster than Quickfix

We've had some fantastic improvements in encode/decode performanceFor the same message, Fix8 encodes 2.8 times faster and decodes 1.6 times faster averaging 2 times over Quickfix. In other words, reduces encode latency by 64% and reduces decode latency by36%See Performance to see how we substantiate this shameless bragging.


2. Unit testing

The first phase of our unit testing framework is complete. We have incorporated the following test catagories with a total of 31 individual tests. We will continually add more....
message, filelogger, filePersister, sessionId, sessionTest
We have also improved the supplied harness.cpp test application. This can be used to script load and replay FIX messages to in a session. This mechanism can be used to automate testing.
