What is CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

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.

6.3

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.

5.0

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.
