What is Knock?

Notification infrastructure grows a memory: workflows can now wait on the real world.

Knock sells notification infrastructure — workflows, broadcasts, in-app guides, and multi-channel delivery that product teams wire up instead of building themselves. July was dense and unusually broad: a rebuilt Notion-style template editor, saved views and tags, schema management for how properties surface across the dashboard, passkey login, branch rebasing, and sandbox test runs that skip delay steps. Underneath the polish, two structural additions landed — message events syncing into the data warehouse, and a workflow step that pauses until an event arrives.

What is MinIO?

MinIO narrows its open build to a storage engine and points paying users at AiStor

MinIO is a Go S3-compatible object store, and its open-source distribution is being deliberately narrowed. One release in this window deprecates the embedded UI console into a separate object-browser project, removes external IDP login via LDAP and OIDC outright, and drops boringcrypto in favour of the GOFIPS environment variable — with paying customers told to migrate to the commercial AiStor product. Everything around it is engine work: ILM and decommissioning correctness, a Go 1.24 toolchain move, a CVE patch, and a new endpoint to revoke STS tokens.

Notification infrastructure grows a memory: workflows can now wait on the real world.

◆ Current state

Knock sells notification infrastructure — workflows, broadcasts, in-app guides, and multi-channel delivery that product teams wire up instead of building themselves. July was dense and unusually broad: a rebuilt Notion-style template editor, saved views and tags, schema management for how properties surface across the dashboard, passkey login, branch rebasing, and sandbox test runs that skip delay steps. Underneath the polish, two structural additions landed — message events syncing into the data warehouse, and a workflow step that pauses until an event arrives.

◆ Where it's heading

The developer-workflow half of the product is being treated like a codebase: branches that rebase onto main, tests that run in sandbox without delivering, tags and saved views for navigating a growing workspace. The engine half is moving in a different direction — toward workflows that hold state over time. A wait-for-event step, combined with the Clay data source triggering messaging as rows finish enriching, describes journeys rather than notifications. The analytics work is arriving twice over: raw events into the warehouse for teams with their own stack, and natural-language questions to the Knock agent for teams without one.

◆ Prediction

Wait-for-event is the primitive that makes journey-shaped use cases possible, so expect the next releases to address what it exposes — timeouts, observability into workflows sitting paused, and limits on how long one can wait before it becomes a support problem.

MinIO narrows its open build to a storage engine and points paying users at AiStor

◆ Current state

MinIO is a Go S3-compatible object store, and its open-source distribution is being deliberately narrowed. One release in this window deprecates the embedded UI console into a separate object-browser project, removes external IDP login via LDAP and OIDC outright, and drops boringcrypto in favour of the GOFIPS environment variable — with paying customers told to migrate to the commercial AiStor product. Everything around it is engine work: ILM and decommissioning correctness, a Go 1.24 toolchain move, a CVE patch, and a new endpoint to revoke STS tokens.

◆ Where it's heading

The direction is an open-core line hardening its boundary. The features that made the free binary a finished product — a bundled console, enterprise identity integration, FIPS support — are being unbundled, while what stays open is the storage engine plus enough API surface (STS revocation, replication metrics labels, checksum preservation on CopyObject) for operators to build their own front end. The bugfix releases surrounding the break all sit below that line, which is consistent rather than coincidental.

◆ Prediction

Expect the open distribution to keep converging on a headless, API-only server, with any remaining operator-facing convenience features candidates for relocation to AiStor.
