Overview

OpenSpec is a project developed by Fission AI, tracked as one of three monitored repositories in the AI Digest. The project has maintained version stability with v1.2.0 since early March 2026, indicating either feature completion or a maintenance-focused period.

Timeline

  • 2026-05-03-AI-Digest — No new release; v1.3.1 from April 21 remains latest, now twelve days old. Sub-1.5-week cadence is normal; quiet patch continues.

  • 2026-05-02-AI-Digest — No new release; v1.3.1 from April 21 remains latest, now eleven days old. Sub-1.5-week cadence is the running baseline; release gap is unremarkable.

  • 2026-03-08-AI-Digest - OpenSpec v1.2.0 tracking begins

  • 2026-03-12-AI-Digest - Version remains at v1.2.0 (no updates since initial tracking)

  • 2026-03-17-AI-Digest - Version stability maintained

  • 2026-03-22-AI-Digest - No updates reported

  • 2026-03-27-AI-Digest - No updates reported

  • 2026-03-31-AI-Digest - No updates reported

  • 2026-04-06-AI-Digest — v1.2.0 remains latest; no new release since February.

  • 2026-04-07-AI-Digest — No new release; v1.2.0 current with profiles system and Pi/Kiro IDE support

  • 2026-04-07-AI-Digest — No new release; v1.2.0 from February remains latest with support for 21 AI tools.

  • 2026-04-08-AI-Digest — No new release; v1.2.0 still current. Issue activity continues through early April but no new tagged releases.

  • 2026-04-22-AI-Digest — v1.3.1 (April 21, 2026) lands with path and telemetry fixes: canonical artifact path resolution through realpath, glob artifact output corrections, cleaner --json output (preventing spinner progress from contaminating stderr when agents parse combined output), and telemetry reliability in firewalled networks. v1.3.1 is the second April release after v1.3.0’s April 11 feature drop (Junie/Lingma/ForgeCode/IBM Bob tool integrations) — confirming OpenSpec is running a point-release pattern where minor fixes land within two weeks of feature drops, rather than the “monthly cadence” assumption tracked through early April.

  • 2026-04-30-AI-Digest — No new release; v1.3.1 (April 21) remains latest as nine days have elapsed since the last release.

  • 2026-05-29-AI-Digest — Still unchanged on v1.3.1 (2026-04-21, now ~38 days old) — no new release this week. The cadence read has now firmly crossed from “normal envelope” into cooling: at ~38 days the gap is past the historical v1.2→v1.3 spacing, so the next tag is overdue rather than merely awaited.

  • 2026-06-02-AI-Digest — v1.4.0 “Kimi CLI, Mistral Vibe” ships 2026-06-01 ~21:27 UTC — the cadence-break recovery that prior digests had been flagging lands ~41 days after v1.3.1, closing the “firmly stale” gap. Two new agent integrations are skills-only: Kimi CLI (skills under .kimi/skills/) and Mistral Vibe (skills under .vibe/skills/). Sync skills are enabled by default in new installs — a behaviour change worth knowing before the next bootstrap. Requirement headers now parse case-insensitively (real footgun), and oh-my-zsh completion is fixed. The skills-only agent-integration pattern is now four integrations in two releases — the through-line.

  • 2026-06-04-AI-Digest — v1.4.1 “Update Fix” ships 2026-06-03 — a single-issue patch on the v1.4.0 release from June 1. Projects carrying their own workspace.yaml can run openspec update again — the v1.4.0 path broke this for Dagster-style workspace configs. Small patch, but it unblocks a real user-visible regression that hit anyone trying to update inside an existing monorepo workspace.

  • 2026-06-05-AI-Digest — Unchanged today; v1.4.1 “Update Fix” (2026-06-03) remains latest, the single-issue patch on v1.4.0 covered in 2026-06-04-AI-Digest. No new release in the last 24 hours.

  • 2026-06-06-AI-Digest — No new release. v1.4.1 “Update Fix” (2026-06-03), the workspace.yaml regression fix covered in 2026-06-05-AI-Digest, remains the current tag. Within the 7-day window but nothing new to add — cadence-watch only.

  • 2026-06-07-AI-Digest — No new release. v1.4.1 (2026-06-03) — the single-issue “Update Fix” patch that restored openspec update for projects carrying their own workspace.yaml (e.g. Dagster) — remains the latest. Quiet four days; nothing new to report against 2026-06-04-AI-Digest‘s coverage.

Version Status

  • Current version - v1.4.1 (June 3, 2026)
  • Previous versions - v1.4.0 (June 1, 2026), v1.3.1 (April 21, 2026), v1.3.0 (April 11, 2026), v1.2.0 (February 2026)
  • Status - Active point-release cadence after cadence-break recovery

Development Pattern

OpenSpec demonstrates a different development pattern compared to Beads:

  • Stability-focused - No rapid iteration or minor version bumps
  • Feature-complete - Suggests v1.2.0 meets project goals
  • Maintenance mode - Possible transition to maintenance after completion

Project Context

OpenSpec is maintained by Fission AI and serves as one of three primary repositories monitored for developments in the AI/developer tools ecosystem alongside Beads and other tracked projects.

Repository Status

OpenSpec remains available as an open-source project with development tracking through the AI Digest monitoring system.
