Quick answer: The CompTIA CySA+ v4 (CS0-004) release date is on or around June 23, 2026. That same day, the current CS0-003 (v3) exam retires - there is no extended overlap. Your exam registration date decides which version you sit: schedule and pass before June 23, 2026 to take CS0-003, or plan for CS0-004 if your test date is on or after that day. The exam format does not change, and any CySA+ you have already earned stays valid.
This is the definitive transition timeline: the key dates, why the change is happening, what it means for your existing certification, and exactly what to do now.
