CRI-O vs Robusta: at a glance
What is CRI-O?
CRI-O ships patch releases across three branches with empty change notes
CRI-O's changelog is patch releases across supported branches, now including v1.35.x alongside v1.34.x. The three newest notes, v1.35.10, v1.34.15 and v1.34.14, list empty Dependencies and Feature sections with no items. Earlier 1.34 patches carried dependency updates and regression fixes.
What is Robusta?
Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.
After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.

◆ Current state
CRI-O's changelog is patch releases across supported branches, now including v1.35.x alongside v1.34.x. The three newest notes, v1.35.10, v1.34.15 and v1.34.14, list empty Dependencies and Feature sections with no items. Earlier 1.34 patches carried dependency updates and regression fixes.
◆ Where it's heading
The project is in steady maintenance on several Kubernetes-aligned branches. The published notes have stopped describing changes, so users cannot see what a patch contains from the feed.
◆ Prediction
More patch releases on 1.34 and 1.35 are likely at the same cadence; whether notes will return is unclear.
Robusta
5.0INFRA · APIS
Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.
◆ Current state
After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.
◆ Where it's heading
The release mixes multi-tenant Prometheus support, Holmes AI assistant reliability and fewer SaaS dependencies for self-hosted installs. CVE patching remains a constant in every tag.
◆ Prediction
Further Holmes integration work and multi-tenant monitoring changes are the likeliest next items, alongside the usual CVE bumps.
