+### System Monitoring
+
+A new local system monitoring feature has been added, allowing to monitor numerous vital server metrics.
+
+Most important metrics will be displayed when doing a pm2 ls:
+
+```bash
+┌─────┬─────────────────┬─────────────┬─────────┬─────────┬──────────┬────────┬──────┬───────────┬──────────┬──────────┬──────────┬──────────┐
+│ id  │ name            │ namespace   │ version │ mode    │ pid      │ uptime │ ↺    │ status    │ cpu      │ mem      │ user     │ watching │

+
+All server metrics will be available to pm2.io:

+#### Disabling system monitoring
+
+```
+# Disable system monitoring
+pm2 set pm2:sysmonit false
+# Enable system monitoring
+pm2 set pm2:sysmonit true
+```
+
+### PM2.io bandwidth reduction
+
+Data quantity sent from PM2 to PM2.io has been reduced by 80%, thanks for a json patch differential system. Much more data can now be exposed (metrics, actions) to PM2.io
+
+### Other fixes
+
+- feat: added args and full script path to monitoring data
+- fix: regular local ip check
+- fix: pm2 agent watchdog has been consolidated and fixes freezing issues
+- fix: modules bumped
+
 ## 4.5.6
 
 - all submodules version bumped
