What is ESPHome?

ESPHome's July line is all maintenance: bot bumps, build fixes, one breaking ethernet change.

ESPHome is four patches into the 2026.7 cycle, and the patch content is dominated by bundled esphome-device-builder bumps, dependabot updates, and toolchain fixes on the ESP-IDF and Zephyr build paths. The user-visible fixes are narrow and hardware-specific: sensor readings on emc2101, haier and as3935, epaper init defaults, and device adoption failing on first attempt because the git clone cache was unlocked. 2026.7.3 carried an explicitly flagged breaking change to ENC28J60 SPI chip-select hold time.

What is werf?

Three release channels at once as werf 3 takes shape beside a still-shipping 2.75.

werf publishes into parallel channels simultaneously — v2.75.3 tagged beta, ea and stable landed the same minute as v2.75.4 for alpha, while the v3 line runs separately through 3.0.2, a 3.0.0 alpha and a 3.1.0 dev build. The 2.x entries are corrective: buildah pull retries and serialisation, a stapel service script made executable regardless of umask, host cleanup no longer wiping other werf versions' git cache. The v3 entries carry the actual features.

ESPHome's July line is all maintenance: bot bumps, build fixes, one breaking ethernet change.

◆ Current state

ESPHome is four patches into the 2026.7 cycle, and the patch content is dominated by bundled esphome-device-builder bumps, dependabot updates, and toolchain fixes on the ESP-IDF and Zephyr build paths. The user-visible fixes are narrow and hardware-specific: sensor readings on emc2101, haier and as3935, epaper init defaults, and device adoption failing on first attempt because the git clone cache was unlocked. 2026.7.3 carried an explicitly flagged breaking change to ENC28J60 SPI chip-select hold time.

◆ Where it's heading

The July line is stabilisation rather than expansion — the feature content lives in the 2026.7.0 release the beta tags led up to, and everything since has been build-system and per-component correction. Automated bumps now make up a large share of each patch note, which makes the changelog a poor read on what actually changed for users. The through-line is a build toolchain ESPHome increasingly owns end to end, via the bundled device-builder it keeps rev-ing.

◆ Prediction

Expect the 2026.8.0 betas to open shortly and reset the cycle, with one or two more bump-heavy patches closing out the 2026.7 line first.

5.0

Three release channels at once as werf 3 takes shape beside a still-shipping 2.75.

◆ Current state

werf publishes into parallel channels simultaneously — v2.75.3 tagged beta, ea and stable landed the same minute as v2.75.4 for alpha, while the v3 line runs separately through 3.0.2, a 3.0.0 alpha and a 3.1.0 dev build. The 2.x entries are corrective: buildah pull retries and serialisation, a stapel service script made executable regardless of umask, host cleanup no longer wiping other werf versions' git cache. The v3 entries carry the actual features.

◆ Where it's heading

The v3 work is about making builds predictable and inspectable: embedded kubeconform schemas, a per-project meta-repo safeguard with a migration path, additional patches files with the defaults disableable, and repo-built scratch images made readable by dive. Meanwhile v3 alphas are restoring flags that v3 had dropped, which suggests the major is being trimmed and then walked back based on review. Dockerfile fidelity — COPY --parents, COPY/ADD --exclude in staged builds — is a recurring thread across both lines.

◆ Prediction

Expect the 2.75 line to keep taking build-backend fixes while v3 stabilises, with more v2 flags restored in v3 alphas as review findings land before the major reaches a stable channel.
