On average, the FreeBSD security team releases about 2 security advisories per month. AI has changed this.
In April, the project released 8 advisories, with 6 powered by AI. In May, the count decreased slightly to 7.
Today I took a look at the FreeBSD Security Advisory page to check the latest advisory count.
June saw the most number of advisories ever published in project history: 25.

About
I was a captain in the United States Air Force who formally trained as an intelligence officer. I later worked in information warfare. I promoted the concept that "prevention eventually fails" in my first book (2004) and developed tactics, operations, and strategy to detect and respond to nation-state and criminal computer intrusions. I created the GE-CIRT and was Mandiant's first CISO. I currently advocate #NetworkSecurityMonitoring for @corelight. My latest books are here #ad https://amzn.to/3B2AcMc
