What is carrier?

carrier's 0.3.0 quietly rewrites how crated functions see each other — and breaks code that relied on the old rules.

carrier packages an R function together with the data it needs so it can be shipped to another process or machine. 0.3.0 changed the semantics of functions passed through ...: they are now re-crated inside the main crate environment instead of inheriting from wherever they were defined. That fixes helper functions failing to resolve each other remotely, and stops local environments dragging large objects into the payload.

What is ESPHome?

ESPHome ships on a calendar, and the August beta train is now five builds deep

The 2026.8.0 beta line has reached its fifth build in six days. Every one of them is a version-bump merge commit with no release notes — b5 is 70 characters, and that is the entire record. The last entries with readable content are the 2026.7 patch releases, which is where per-component fixes and contributor work actually become visible.

carrier's 0.3.0 quietly rewrites how crated functions see each other — and breaks code that relied on the old rules.

◆ Current state

carrier packages an R function together with the data it needs so it can be shipped to another process or machine. 0.3.0 changed the semantics of functions passed through ...: they are now re-crated inside the main crate environment instead of inheriting from wherever they were defined. That fixes helper functions failing to resolve each other remotely, and stops local environments dragging large objects into the payload.

◆ Where it's heading

Each release tightens the boundary between a crate and its surroundings. 0.2.0 introduced .parent_env defaulting to baseenv() to cut the crate off from the global search path and made unnamed ... arguments an error instead of a silent drop; 0.3.0 finishes the job by controlling the environment chain of the packed closures themselves. The package is trading backwards compatibility for predictable, self-contained payloads — a reasonable bet for something whose failures otherwise surface on a remote worker.

◆ Prediction

The 0.1.0 notes promised an automatic dependency-detection mode to replace explicit packing; nothing since has delivered it, and with the environment semantics now settled that is the obvious next move — though the entries give no date for it.

ESPHome ships on a calendar, and the August beta train is now five builds deep

◆ Current state

The 2026.8.0 beta line has reached its fifth build in six days. Every one of them is a version-bump merge commit with no release notes — b5 is 70 characters, and that is the entire record. The last entries with readable content are the 2026.7 patch releases, which is where per-component fixes and contributor work actually become visible.

◆ Where it's heading

The cadence is the product. Betas arrive every day or two as bump merges carrying no notes, the final release points at a changelog URL, and the real detail lands in the patch releases that follow it. Five betas in this cycle against four in the last suggests a slightly longer stabilization, but the feed gives no way to tell what is being stabilized. Anyone tracking ESPHome from this feed learns the release rhythm and nothing about the releases.

◆ Prediction

Expect 2026.8.0 final within days, followed by the 2026.8.x patch releases that will carry the first readable account of what the August cycle actually changed.
