Ubuntu Security Update Metrics
This is a collection of metrics on security updates published in Ubuntu, summarized from several perspectives. These metrics are regularly calculated from the Ubuntu Security Notices list.
Summary
USNs published per month  |
CVE fixes per month  |
Source packages fixed per month  |
Regressions per month  |
Supported releases
Graphs with raw data ('r') and plot commands ('p'). 'n/a' used when not enough data is available (eg, first month of release or zeros for each month).
