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 OctoPrint?

OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.

The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

5.0

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.

2.5

OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.

◆ Current state

The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

◆ Where it's heading

Serial is being demoted from the way OctoPrint talks to a printer to one implementation of a connector interface, which is the structural precondition for supporting printers that speak something else. The cost is deliberate: rc1 removes deprecated APIs, warns that plugins will break, and points users at a recovery page to restart in safe mode. A maintainer running a long public RC cycle on a single-maintainer project is managing that breakage rather than rushing past it.

◆ Prediction

Expect further RCs until the connector migration stops producing reports, with the plugin ecosystem's readiness — not the core code — deciding when 2.0.0 goes stable.
