ESPHome vs stochvol
A side-by-side editorial comparison of ESPHome and stochvol — release velocity, themes, recent moves, and the top alternatives to consider.
ESPHome vs stochvol: at a glance
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 stochvol?
A Bayesian volatility sampler in its maintenance decade, paying for its own speed
stochvol runs MCMC for stochastic volatility models, with a C++ sampler underneath an R interface. Five years of releases in this window contain no new models: the work is compiler and dependency compatibility, CRAN check notes, and a steady trickle of corrections to the sampler itself. Its methodological milestone, the Journal of Statistical Software paper, is recorded in a 2021 tag.

◆ 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.

A Bayesian volatility sampler in its maintenance decade, paying for its own speed
◆ Current state
stochvol runs MCMC for stochastic volatility models, with a C++ sampler underneath an R interface. Five years of releases in this window contain no new models: the work is compiler and dependency compatibility, CRAN check notes, and a steady trickle of corrections to the sampler itself. Its methodological milestone, the Journal of Statistical Software paper, is recorded in a 2021 tag.
◆ Where it's heading
This is what a finished computational package looks like. The formula interface arrived at 3.1.0 and nothing has been added since; what changes is the ground underneath — RcppArmadillo major versions, UBSan checks, error-handling conventions moving from Rf_error to Rcpp::stop for correct memory management. The recurring pattern worth watching is that several releases fix real errors in the sampler's proposal distributions, found by users and by CRAN's own instrumented checks rather than by the maintainer.
◆ Prediction
Nothing in these notes suggests new methodology. Expect the next release when RcppArmadillo or a CRAN check flavour forces one, and treat any bug report against the samplers as the more consequential event.
