What is Dokku?
Dokku is quietly turning into a k3s front-end with a JSON-first CLI.
The 0.38 patch line keeps shipping small releases with real features in them. v0.38.27 drops the local-image requirement for k3s deploys, reports Traefik DNS-provider variables as global keys, adds storage directory mode and removal flags, and introduces a vector-cron-sink so scheduled cron output has somewhere to go. It follows v0.38.26, which brought wildcard domains, custom cert issuers, and kernel sysctls to the k3s scheduler.
What is Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.

Dokku

Dokku is quietly turning into a k3s front-end with a JSON-first CLI.
◆ Current state
The 0.38 patch line keeps shipping small releases with real features in them. v0.38.27 drops the local-image requirement for k3s deploys, reports Traefik DNS-provider variables as global keys, adds storage directory mode and removal flags, and introduces a vector-cron-sink so scheduled cron output has somewhere to go. It follows v0.38.26, which brought wildcard domains, custom cert issuers, and kernel sysctls to the k3s scheduler.
◆ Where it's heading
Two threads run through almost every release: closing the gap between the k3s scheduler and the classic single-host path, and making every command machine-readable. The k3s work has moved from basic scheduling to the operational details — certificates, DNS, sysctls, and now deploys that no longer assume a local Docker image — which is the sequence a project follows when it expects the Kubernetes path to become the default rather than the alternative.
◆ Prediction
Expect the remaining k3s parity gaps to keep closing one release at a time, and expect the logging work started with vector-cron-sink to extend to other task types that currently have no sink.
Merge
6.3INFRA · APIS
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
