What is ESPHome?

ESPHome ships on a calendar, and the August beta train is now five builds deep

The 2026.8.0 beta line has reached its fifth build in six days. Every one of them is a version-bump merge commit with no release notes — b5 is 70 characters, and that is the entire record. The last entries with readable content are the 2026.7 patch releases, which is where per-component fixes and contributor work actually become visible.

What is simDAG?

simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.

simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.

ESPHome ships on a calendar, and the August beta train is now five builds deep

◆ Current state

The 2026.8.0 beta line has reached its fifth build in six days. Every one of them is a version-bump merge commit with no release notes — b5 is 70 characters, and that is the entire record. The last entries with readable content are the 2026.7 patch releases, which is where per-component fixes and contributor work actually become visible.

◆ Where it's heading

The cadence is the product. Betas arrive every day or two as bump merges carrying no notes, the final release points at a changelog URL, and the real detail lands in the patch releases that follow it. Five betas in this cycle against four in the last suggests a slightly longer stabilization, but the feed gives no way to tell what is being stabilized. Anyone tracking ESPHome from this feed learns the release rhythm and nothing about the releases.

◆ Prediction

Expect 2026.8.0 final within days, followed by the 2026.8.x patch releases that will carry the first readable account of what the August cycle actually changed.

simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.

◆ Current state

simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.

◆ Where it's heading

The package has been widening what a simulation can represent rather than deepening any one node. Networks arrived in 0.4.0 so individuals could depend on each other, discrete-event simulation in continuous time arrived in 0.5.0 as an alternative to the discrete-time engine, and 1.0.0 connected the two by letting continuous hazards feed the event-driven path. Alongside that, node types keep accumulating for outcome families the framework could not previously generate.

◆ Prediction

Expect the node library to keep expanding into outcome types the discrete-event engine can now support, though the recent releases suggest upstream dependency churn will keep consuming release slots.
