A monthly release train where the substance hides in the patch releases

esp32firmwarebuild-toolchainmemory-safetyrelease-trainhome-automation
◆Current state
ESPHome runs a strict calendar train — a 2026.7.0 feature release preceded by four betas, then a steady run of .1/.2/.3 patches. The patch releases carry most of the visible work: per-component fixes across BLE, WiFi, Ethernet, display and audio drivers, plus repeated bumps of the bundled esphome-device-builder. The 2026.7.0 entry itself links out to a changelog rather than listing anything.
◆Where it's heading
Two threads run through the window. The first is multi-platform build hardening — honoring compile process limits in native ESP-IDF builds, widening the app source glob to .cc/.cxx/.c++, fixing submodule cloning on the esp-idf toolchain, and Zephyr/nRF52 SDK discovery. The second is memory and input safety: escaping SSIDs in captive portal JSON, locking scan results shared with the web task, dropping oversized ESP-NOW frames, and fixing a use-after-return in the IDF HTTP backend.
◆Prediction
The cadence points to a 2026.8.0 beta series opening within weeks, with the bundled device-builder continuing to move on its own faster track. What lands in that feature release is not visible from these entries, since the feature-release notes are published off-site.

◆Recent moves

  1. 5d ago

    Captive portal escaping, WiFi scan locking, ENC28J60 timing fix

    The largest patch of the cycle, sitting squarely in the safety thread: SSIDs are escaped when building captive portal config JSON and WiFi scan results shared with the web task are now locked. It also carries a breaking change to SPI chip-select hold time on the ENC28J60 Ethernet controller, so affected boards need re-verification.

    Dependency bumps with a sen5x model override

    Mostly version bumps — aioesphomeapi, sendspin-cpp, and the bundled device-builder — alongside a mipi_spi partial-update fix. The one user-facing addition is a sen5x option to override sensor autodetection, too narrow to shift the release out of maintenance territory.

    Sensor accuracy fixes and IDF/Zephyr build repairs

    A broad correctness pass across the driver layer: emc2101 no longer reports negative temperatures as large positives, haier stops publishing the coil temperature as outdoor defrost, and as3935_i2c uses repeated start when reading registers. The build-hardening thread continues with framework mirror selection, Zephyr digital_write, and nRF52 SDK discovery.

    ESPHome 2026.7.0 monthly feature release

    The feature release the July betas were building toward, and the anchor for the three patches that followed. The entry body is only a link to the hosted changelog, so what actually shipped is not visible in the feed itself.

    2026.7.0 beta 4

    The last beta before 2026.7.0, published as a bare version-bump merge with no release notes. It marks a point on the release train rather than a change users would notice.

    2026.7.0 beta 3

    Another version-bump merge in the July beta sequence, carrying no described changes. These beta tags inflate the apparent release cadence without adding user-visible surface.
