What is Resend?

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

What is Strimzi?

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

◆ Current state

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

◆ Where it's heading

Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.

◆ Prediction

Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

◆ Current state

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

◆ Where it's heading

Post-1.0 Strimzi is spending its cycles on how the operator manages Kubernetes resources rather than on new Kafka surface. ServerSideApplyPhase1 has gone alpha to GA and is now always on, and 1.2.0 changes install-time defaults toward Restricted Pod Security Standard security contexts and volume-mounted Service Account tokens. A second candidate carrying one logging fix says the cycle is converging rather than still absorbing change — the CRD v1-only requirement from 1.0.0 remains the loudest thing in every release body.

◆ Prediction

Expect 1.2.0 final shortly with no further candidates, and the next cycle to advance one of the open feature gates — UseBackgroundPodDeletion is the likeliest to move from alpha to beta.
