What is Knock?
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
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.

Knock

Knock is hardening for enterprise buyers while its agent takes over the analysis work.
◆ Current state
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
◆ Where it's heading
Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
◆ Prediction
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.

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.
