News, announcements, and updates from the Hop3 project.

2026¶

June¶

• June 24: Hop3 0.6.1 Released - Hop3 0.6.1 consolidates the deploy-target model into a single "context" noun, pins nixpkgs across every Nix recipe for reproducible builds, ships an experimental email/SMTP addon, and lands a broad stability pass across the test lab, CI, and app packaging.
• June 22: Hop3 0.6.0 Released - Hop3 0.6.0 adds per-app resource limits and volumes, a much richer addon-management surface, a signed app catalog, and publishes the full design record — the platform-capability layer on top of 0.5's consolidation.
• June 19: The Test Lab: Making the Nightly Suite Legible - The nightly Test Lab — a Hop3-hosted web app that provisions cloud servers, runs the whole suite, and turns every failure into a queryable, trend-aware report. (Part 5 of 5)
• June 19: The Test Runner: Why hop3-test Exists - Why Hop3 needed a bespoke test runner beyond pytest, what it takes to run it, and the one deploy-and-verify path it owns. (Part 4 of 5)
• June 19: Testable Docs: Tutorials That Run Themselves - How Hop3 keeps its tutorials correct — validoc runs the documentation's own commands against a real server and asserts the results. (Part 3 of 5)
• June 19: The Demos: One Artifact, Three Jobs - Why every Hop3 demo is three things at once — a tutorial, a screencast, and a regression test — and how the launcher runs them. (Part 2 of 5)
• June 19: How Hop3 is Tested - A map of how Hop3 tests itself — three runners, three layers, four speed tiers, and why each one exists. (Part 1 of 5)
• June 08: Hop3 0.5.0 Released - Hop3 0.5.0 is a consolidation release — a reworked CLI, reproducible Nix builds, four waves of security hardening, and deploy failures you can actually diagnose.
• June 03: Hop3 at OW2Con 2026 — NGI Zero Success Stories - Talk in the NGI Zero 'Success Stories' session at OW2Con 2026: what the Nix Integration for Hop3 grant delivered, and what comes next.
