What is HAProxy Kubernetes Ingress Controller?
Nine months into the 3.2 line, HAProxy Ingress is still repairing ssl-passthrough and ingress merge order.
The controller ships a steady patch cadence on the 3.2 branch, roughly one release every two to four weeks. Content is almost entirely correctness work: ssl-passthrough handling and the rules that decide which Ingress object owns a shared backend. Feature additions are absent from the last ten releases; dependency bumps to k8s.io and golang.org/x packages appear in most of them.

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.

HAProxy Kubernetes Ingress Controller
2.5INFRA · APIS
Nine months into the 3.2 line, HAProxy Ingress is still repairing ssl-passthrough and ingress merge order.
◆ Current state
The controller ships a steady patch cadence on the 3.2 branch, roughly one release every two to four weeks. Content is almost entirely correctness work: ssl-passthrough handling and the rules that decide which Ingress object owns a shared backend. Feature additions are absent from the last ten releases; dependency bumps to k8s.io and golang.org/x packages appear in most of them.
◆ Where it's heading
v3.2.13 is the largest release in the window and marks a shift from patching individual ssl-passthrough bugs to defining the semantics properly: backends are now reconciled rather than recreated, the invariant is applied before anything that can fail, and controller-owned backend state survives a failed transaction. Alongside it, ingress merge order became deterministic — oldest ingress first — and the first Ingress to constitute a backend now owns it, with the annotations a losing Ingress forfeits named explicitly. That pairing suggests the team traced a class of flapping and non-reproducible config bugs back to undefined ordering.
◆ Prediction
Expect the next few releases to stay on the 3.2 patch line, adding tests around the new ownership and passthrough invariants rather than new annotations.
Knock
6.3INFRA · APIS
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.
