Two major bug fixes:

• Fixing a performance regression with the addCodeAddrCB (#42): Since 0.6, this API would trigger a complete cache flush forcing the engine to regenerate all the instrumented code after each call. Since this API is used inside VM:run(), this had the effect of completely canceling precaching optimization where used.
• Fixing support for AVX host without AVX2 support (#19): Context switching was wrongly using AVX2 instructions instead of AVX instructions causing segfaults under hosts supporting AVX but not AVX2.

Mostly a maintenance update:

• Important performance improvement in the core engine (#30) This slightly changes the behavior of VMEvents.
• Fix the addCodeAddrCB API (#37)
• atexit and getCurrentProcessMap in python bindings (#35)
• Fix getInstAnalysis on BASIC_BLOCK_ENTRY (#28)
• Various documentation improvements (#34, #37, #38, #40) and an API uniformisation (#29)

This is the first public release of QBDI. This is not perfect, there are areas of improvement, but it is a first step in the right direction :-)
