How this is made. Compiled automatically from GitHub releases API, Hacker News (Algolia search API), CISA Known Exploited Vulnerabilities catalog. Releases cover about 60 widely used projects and include minor/major versions and any release mentioning a security fix. It is a digest, not a complete list: it can miss things. Always check the linked source before acting.
