Wizzo v0.25.0 Release Notes

Fixes

• Finalized Sprint 25 infrastructure hardening: dedicated Upstash Redis topology with documented load test, failover drill, and post-cutover soak evidence ahead of RC readiness.
• Activated the automated performance alerting pipeline with updated runbooks, CLI drill tooling, and PagerDuty/Slack/Jira artefacts so Ops can respond to mentor latency, voice accuracy, and ML confidence regressions.
• Approved the multi-region cache replication strategy, capturing EU replica telemetry, CDN fallback smoke tests, and Grafana dashboards to keep global performance within targets.
