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 frontmatter and NetBox — release velocity, themes, recent moves, and the top alternatives to consider.
A small R parser quietly becoming format-agnostic about front matter.
frontmatter extracts and writes YAML or TOML front matter from text documents, with a C++ parser and pluggable YAML and TOML backends. Three releases across six months have taken it from read-only parsing to full roundtrip and then to inferring format automatically. Its scope is deliberately narrow: locating and delimiting the metadata block, and delegating the actual parsing to other packages.
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.

Three releases across six months have taken it from read-only parsing to full roundtrip and then to inferring format automatically. Its scope is deliberately narrow: locating and delimiting the metadata block, and delegating the actual parsing to other packages.
Each release widens the set of files it recognises without widening what it claims to do — standard YAML and TOML fences first, then comment-wrapped R and Python variants and PEP 723 inline script metadata, then shebang-prefixed scripts. The complementary thread is preserving what it found: format and fence type are attached as attributes so a document can be rewritten in the style it arrived in. The remaining rough edge is acknowledged in the notes, since comments and formatting inside the front matter do not survive a roundtrip.
Expect further delimiter styles as they appear in the wild, and likely work on making the roundtrip preserve comments and formatting, which the package currently flags as imperfect.

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.
