Resend
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
A side-by-side editorial comparison of Dokku and NetBox — release velocity, themes, recent moves, and the top alternatives to consider.
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.
NetBox adds a cooling data model — the first new infrastructure domain since power
After a 4.6 patch cycle spent almost entirely on GraphQL query cost and permission correctness, NetBox has opened its 4.7 line with a beta that is the opposite kind of release. It introduces cooling infrastructure as a first-class modeling domain, migrates nested group models off django-mptt onto a PostgreSQL ltree column, replaces the Service protocol/ports fields with a unified port_mappings structure, and raises the floor to PostgreSQL 15 and Redis 6. The breaking-change list runs longer than most NetBox releases run in total.

It follows v0.38.26, which brought wildcard domains, custom cert issuers, and kernel sysctls to the k3s scheduler.
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.
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.

The cooling model is deliberately shaped as a mirror of the existing power model — CoolingSource and CoolingFeed parallel PowerPanel and PowerFeed, CoolingIntake and CoolingOutflow parallel PowerPort and PowerOutlet, with CDUs and manifolds modeled as ordinary devices carrying those components. That symmetry says NetBox intends liquid cooling to be documented with the same rigor as power distribution, not bolted on as attributes. Underneath it, the ltree migration and the deferred search-index rebuild continue the performance thread of 4.6 by other means: instead of trimming queries inside the ORM, 4.7 is changing what the ORM sits on.
Expect at least one more 4.7 beta or release candidate before general availability, with the deprecated NestedGroupModel base class and the retained protocol/ports API fields the most likely sources of follow-up fixes as plugins migrate.
