I don't see any new optimisations.
Agreed, source shows no commits after Testz's, perhaps a malicious binary? Use caution.
Edit: certainly not definitive but... virustotal reports it already scanned cpuminer.exe a little over a week ago and cpuminer-v2.exe when scanned doesnt report the usual bitcoinminer and instead reports malware.gen and dropper.gen https://www.virustotal.com/en/file/2da15bfaffbf018fc5775816b3e0055ec288e2e810790acbaa2f3f2635252a57/analysis/1454168831/
