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 Fission?

Fission's release feed carries only RC tags, and none of them say what shipped

Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.

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.

Fission's release feed carries only RC tags, and none of them say what shipped

◆ Current state

Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.

◆ Where it's heading

What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.

◆ Prediction

This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.
