What is ESPHome?

ESPHome closes the 2026.8 cycle, but the release body is a bare link to the real notes.

The 2026.8.0 cycle closes out: six beta tags across a week, then the stable release. Only the beta 6 entry carries readable content, and it is mostly build work, with noise-c bumps, ccache and apt fixes in CI, a bootloop fix for ESP32-P4 rev3 chips, and restored defaults and files support for image platform entries. The stable release body is a single link to the off-site changelog.

What is rsofun?

An ecosystem model starts tracking carbon isotopes and land-use change.

rsofun wraps the P-model and BiomeE vegetation models in R with Fortran cores, covering photosynthesis, water balance and forest demography, plus Bayesian calibration. The 5.1.0 release is the first in the window to widen what the models simulate rather than reorganise them. Before it, the history is renaming, cost-function rewrites and output-format consistency work.

5.0

ESPHome closes the 2026.8 cycle, but the release body is a bare link to the real notes.

◆ Current state

The 2026.8.0 cycle closes out: six beta tags across a week, then the stable release. Only the beta 6 entry carries readable content, and it is mostly build work, with noise-c bumps, ccache and apt fixes in CI, a bootloop fix for ESP32-P4 rev3 chips, and restored defaults and files support for image platform entries. The stable release body is a single link to the off-site changelog.

◆ Where it's heading

The cadence is unchanged: a monthly train with betas tagged every day or two, most of them empty in this feed. What content does surface skews toward build infrastructure and per-chip fixes rather than new components, which fits a project whose surface area is dominated by breadth of hardware support. Scope for the month is not readable here, and has not been for several cycles.

◆ Prediction

Expect the 2026.9 cycle to open with the same beta cadence within days, and the stable release body to stay a bare changelog link.

An ecosystem model starts tracking carbon isotopes and land-use change.

◆ Current state

rsofun wraps the P-model and BiomeE vegetation models in R with Fortran cores, covering photosynthesis, water balance and forest demography, plus Bayesian calibration. The 5.1.0 release is the first in the window to widen what the models simulate rather than reorganise them. Before it, the history is renaming, cost-function rewrites and output-format consistency work.

◆ Where it's heading

The direction is from a calibration harness toward a model that can answer different questions: isotope fractionation now comes out of the P-model, BiomeE handles land use and land-use change, and forcing can be recycled when a simulation outruns its data. Version stamps are unreliable here, with a v5.0 tag carrying only a build fix and predating v4.4, so the arc reads better through content than through numbering.

◆ Prediction

The isotope work is explicitly unfinished, with a constant atmospheric signature standing in for daily d13c forcing, so the next likely step is accepting that as model input.
