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 Hotjar and NetBox — release velocity, themes, recent moves, and the top alternatives to consider.
Hotjar's update feed stops in April 2025 — the arc it captures ended mid-sentence.
Hotjar's public update feed carries nothing newer than April 2025, and the entries it does carry arrive in duplicate pairs — a short stub and the full post, a few hours apart. What the archive shows is a product that spent 2024 and early 2025 expanding from passive observation (heatmaps, recordings) into active research: unmoderated User Tests, AI tagging of survey responses, and finally prototype testing.
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.
Hotjar's public update feed carries nothing newer than April 2025, and the entries it does carry arrive in duplicate pairs — a short stub and the full post, a few hours apart. What the archive shows is a product that spent 2024 and early 2025 expanding from passive observation (heatmaps, recordings) into active research: unmoderated User Tests, AI tagging of survey responses, and finally prototype testing.
The direction visible in these entries is a move up the research stack — from watching what users did on a live site toward asking them questions and testing designs before they ship. User Tests removed the moderator, AI tagging removed the manual sorting of open-ended responses, and prototype testing removed the requirement that the thing being tested exist yet. Each step cut a person out of the research loop. Whether that arc continued past April 2025 is not something this feed can answer.
No prediction is supportable from these entries. The feed has published nothing for over a year, so any claim about Hotjar's current direction would be invented rather than observed — the only honest read is that this channel has been abandoned or moved elsewhere.

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.
