patchletter vs. alternatives
The market splits in two: release trackers watch forges and registries but carry no security data; CVE services alert on vulnerabilities but never on new versions. patchletter combines vendor releases, actively exploited CVEs (CISA KEV) and end-of-life dates for the infrastructure sysadmins run. The rows where the others come out ahead are in the table too.
