What is Clerk?

Clerk is building auth for machines: API keys, a CLI agents can drive, per-verification pricing.

Two threads dominate. The first is machine authentication: API keys reached general availability with usage-based billing at $0.001 per creation and $0.00001 per verification, and a new CLI is described as a tool for developers and their agents to manage auth and billing. The second is enterprise readiness — Directory Sync (SCIM) generally available with custom attribute mapping and IdP role assignment, plus an Application Logs event stream across auth, billing, and organizations. Dashboard polish and Expo theming fill in around them.

What is Jenkins?

Jenkins is shrinking its own war file and rebuilding its UI, one weekly release at a time

The weekly train is dominated by two long efforts: an incremental redesign of the experimental Manage Jenkins UI, and a deliberate campaign to unbundle plugins from jenkins.war. 2.577 drops bouncycastle, the Command Agent Launcher, JAXB, the SSH server and more, following 2.574's removal of JUnit, Mailer and the matrix plugins. Interleaved security releases ship with no detail beyond a one-line note.

Clerk is building auth for machines: API keys, a CLI agents can drive, per-verification pricing.

◆ Current state

Two threads dominate. The first is machine authentication: API keys reached general availability with usage-based billing at $0.001 per creation and $0.00001 per verification, and a new CLI is described as a tool for developers and their agents to manage auth and billing. The second is enterprise readiness — Directory Sync (SCIM) generally available with custom attribute mapping and IdP role assignment, plus an Application Logs event stream across auth, billing, and organizations. Dashboard polish and Expo theming fill in around them.

◆ Where it's heading

Clerk is extending from human sign-in toward credentials for software acting on a user's behalf, and pricing that surface by the call rather than by the seat. The CLI framing makes the direction explicit: the control plane should be operable by an agent, not only by a person in a dashboard. Meanwhile SCIM, logs, and billing controls are the enterprise checklist that lets it sell upmarket while that bet plays out.

◆ Prediction

Expect the machine authentication suite to deepen around delegated and scoped access for agents — finer-grained key permissions or short-lived credentials — with usage-based pricing extended to whatever ships next.

Jenkins is shrinking its own war file and rebuilding its UI, one weekly release at a time

◆ Current state

The weekly train is dominated by two long efforts: an incremental redesign of the experimental Manage Jenkins UI, and a deliberate campaign to unbundle plugins from jenkins.war. 2.577 drops bouncycastle, the Command Agent Launcher, JAXB, the SSH server and more, following 2.574's removal of JUnit, Mailer and the matrix plugins. Interleaved security releases ship with no detail beyond a one-line note.

◆ Where it's heading

Two releases cutting 20 MB each signal that unbundling is sustained policy, not a one-off — the core is being reduced toward a minimal server with plugins as an explicit choice. The UI work is methodical and unglamorous: scrollable side panels, sticky build bars, standardised dialogs and command palettes. Neither effort is close to finished.

◆ Prediction

More bundled plugins will be pulled in coming releases, and the experimental Manage Jenkins UI should keep absorbing pages until it can drop the experimental label.
