Public release notes for Stack. Use this page to understand what changed, what may break, and which release channel a change belongs to. Every other Stack doc page links here via `stackVersion` frontmatter — see **Documentation index** below. The repository changelog is the canonical technical source: [`stack/CHANGELOG.md`](https://github.com/synth-laboratories/stack/blob/main/CHANGELOG.md). Private launch gates, dogfood evidence, internal waivers, and operator-only incident notes live outside the public docs. ## Channels | Channel | What to expect | | ----------------- | -------------------------------------------------------------------------------------------------------------------- | | `dev` / nightly | Latest usable Stack from main. Good for dogfood and early feedback. May carry known limitations with rollback notes. | | release candidate | Short freeze before stable. Fixes, docs, packaging, and evidence only. | | stable | Supported public release with documented install, update, support, and rollback or migration posture. | ## Public Entry Format Each public entry should include: * version or nightly id; * release channel; * install or update instructions when they changed; * user-visible additions, changes, fixes, and removed behavior; * breaking changes with migration steps; * known limitations that affect first-run or hosted-feature use; * links to docs, GitHub Release, or issue threads when public. Do not include private Linear ids, private eval data, secret names, internal waiver details, customer-specific incidents, or raw proof transcripts here. ## Documentation index Each Stack doc page declares `stackVersion` (and `stackIntroduced` when new) in frontmatter and links here. Use this table to find which release first documented a page or last updated it. | Page | Slug | Introduced | Current as of | | --------------------------------------- | ---------------------- | ---------------------- | ---------------------- | | [Overview](/stack) | `/stack` | `0.1.0` | `0.2.0-dev.20260703.2` | | [Quickstart](/stack/quickstart) | `/stack/quickstart` | `0.1.0` | `0.2.0-dev.20260703.2` | | [Local-only mode](/stack/local-only) | `/stack/local-only` | `0.2.0-dev.20260702.1` | `0.2.0-dev.20260702.3` | | [Connect Synth](/stack/connect-synth) | `/stack/connect-synth` | `0.2.0-dev.20260702.1` | `0.2.0-dev.20260702.3` | | [Hosted ops](/stack/hosted-ops) | `/stack/hosted-ops` | `0.2.0-dev.20260702.1` | `0.2.0-dev.20260702.3` | | [Cockpit](/stack/cockpit) | `/stack/cockpit` | `0.1.0` | `0.2.0-dev.20260703.2` | | [Goal mode & monitor](/stack/goal-mode) | `/stack/goal-mode` | `0.2.0-dev.20260701.1` | `0.2.0-dev.20260703.2` | | [stackd](/stack/stackd) | `/stack/stackd` | `0.1.0` | `0.2.0-dev.20260701.1` | | [Stack MCP](/stack/mcp) | `/stack/mcp` | `0.1.0` | `0.2.0-dev.20260703.2` | | [Configuration](/stack/configuration) | `/stack/configuration` | `0.1.0` | `0.2.0-dev.20260701.1` | | [Hosted inference](/stack/inference) | `/stack/inference` | `0.1.0` | `0.2.0-dev.20260702.3` | | [Optimizers (GEPA)](/stack/optimizers) | `/stack/optimizers` | `0.1.0` | `0.1.0` | ## Entries **Stack nightly `0.2.0-dev.20260703.2`** — Monitor Gardener Goal release on the nightly channel. * **Lights panel:** `/lights on` opens a right-panel cockpit with scrollable and filterable threads, gardener status, actor status, cloud state, local runtime, and usage. `/lights off` closes it without changing the active worker or gardener view. * **Slash commands:** the slash menu now documents `/help`, `/exit`, `/goal`, `/gardener`/`/g`, `/monitor`/`/m`, `/lights`, `/threads`/`/p`, `/mode`/`/work_mode`, `/provider`/`/harness`, `/profile`, `/model`, `/effort`, `/efforts`, `/subagents`, `/usage`, `/experimental`, `/ops`, `/actors`, `/agent`, `/agent-view`/`/a`, `/permissions`/`/perm`, `/settings telemetry`, `/config`, `/details`/`/d`, `/rails`/`/b`, and `/clear`/`/c`. * **Gardener workflow:** `/gardener` opens in the core panel; Stack MCP now gives gardeners owner-route tools for durable worker/meta-thread creation and goal assignment. * **Effort evidence capture:** `stack effort capture` and `stack_effort_record_capture` preserve terminal, browser, screenshot, monitor, benchmark, optimizer, and other ad hoc evidence with capture-oriented receipt metadata. * **Optimizer candidate evidence:** `stack effort optimizer-candidate` and `stack_effort_record_optimizer_candidate` preserve candidate id, score, split, optimizer run id, and artifact provenance for GEPA or hosted optimizer candidates; task-classifier audits verify the typed optimizer-candidate activity receipt and source sidecar. * **Engineering Effort packets:** `stack effort engineering-packet` and `stack_effort_write_engineering_packet` create change summaries with changed files, diff stat, validation, skipped gates, risks, and next action. * **Effort acceptance receipts:** `stack effort acceptance` and `stack_effort_record_acceptance` update one A-level section in `findings/results/acceptance-summary.md`, append typed acceptance activity, and let generated handoffs derive open risk bullets from remaining acceptance work and the latest blocker. * **Effort blocker receipts:** `stack effort resolve-blocker` and `stack_effort_resolve_blocker` preserve resolution evidence for cleared or superseded blockers while keeping Efforts out of a blocked lifecycle state. * **Efforts panel controls:** `/efforts` supports `j/k` selection, `n` new Effort drafting, `h` handoff refresh, `a` archive/activate, `b` current-thread binding, and `r` refresh; `/efforts new`, `/efforts archive`, and `/efforts activate` expose the same lifecycle actions from slash input. * **Goal mode:** worker chat and slash commands stay available while the monitor sidecar is visible. * **Fixes:** repaired transcript blackspace/input placement, blank resumed goal first-paint, terminal exit cleanup, and Lights panel focus stealing. * **Distribution packet:** nightly `aarch64-apple-darwin` artifact prepared with SHA256 `b8a86789405831809683747f85083511e982678c1aadb92d4e3e3fff0c31d526`; hosted release-site contract proof installed the generated manifest and verified version, doctor, demo receipt, and update-check behavior. Known limitation: this is a nightly packet. Stable release signing and attestation remain outside this dev-channel ship. See the repository [`CHANGELOG.md`](https://github.com/synth-laboratories/stack/blob/main/CHANGELOG.md) for the full nightly technical entry. **Stack nightly `0.2.0-dev.20260703.1`** — artifact round-trip, hosted-run watching, per-task preflight, and papercut capture on the nightly channel. * **Round-trip verbs:** `stack pull`, `stack apply`, and `stack push` move optimizer artifacts between hosted runs and the local workspace, recording a typed receipt (sha256 digest, git SHA, backend target) for every transfer. A `stack_list_hosted_artifacts` MCP tool enumerates what a hosted run produced. * **Hosted run watch:** `stack watch` follows a hosted optimizer run from the CLI, and the TUI gains a hosted-watch panel; both support `--once` snapshots and `--replay` over finished runs. * **Per-task doctor:** `stack doctor --task ` preflights a single task pack and classifies failures as auth, quota, config, or transient. * **Papercut capture:** `ctrl+f` (or `/papercut`) records a papercut into the ledger without leaving the session. * **Fixed:** `/profile` now cycles through all four seeded profiles. * **Backfill:** the repository changelog now carries the previously missing `0.2.0-dev.20260702.4` hotfix section (hosted optimizer artifact-name projection fix). See the repository [`CHANGELOG.md`](https://github.com/synth-laboratories/stack/blob/main/CHANGELOG.md) for the full nightly technical entry. **Stack nightly `0.2.0-dev.20260702.3`** — local-only, hosted ops, remote sync, and Synth inference guidance shipped on the nightly channel. * **Added docs:** [Local-only mode](/stack/local-only), [Connect Synth](/stack/connect-synth), and [Hosted ops](/stack/hosted-ops). * **Updated docs:** [Hosted inference](/stack/inference) now distinguishes free aux (`nemotron-3-ultra`) from billed GLM (`glm-5.2`) and states the worker opt-in invariant. * **Updated docs:** [Overview](/stack) and [Quickstart](/stack/quickstart) now point to local-only and hosted-connect flows instead of treating auth as an install prerequisite. * **Nightly refresh:** `0.2.0-dev.20260702.3` carries the Stack telemetry flush endpoint fix used by the activation funnel usage-stage proof. * **Known limitation:** this is a nightly, not a stable `0.3.0` cut. Stable promotion remains a separate operator decision. See the repository [`CHANGELOG.md`](https://github.com/synth-laboratories/stack/blob/dev/CHANGELOG.md) for the full nightly technical entry. **Stack sidecar monitor** (`0.2.0-dev.20260701.1`, `dev` / nightly) — goal mode now runs a monitor agent that gives you a separate, higher-level stream for long runs. * **Added:** `/goal` mode defaults to a **Sidecar events** feed instead of the worker's raw tool tape. Press `a` for the agent tape, `t` for the monitor's own thread, `e` for events. * **Added:** a **monitor agent** paired 1:1 with the worker narrates meaningful progress, steers the worker when it stalls, and posts typed updates via `stack_monitor_goal_status` (headline, note, metric) rendered as a headline strip and milestone timeline. * **Added:** **completion audit** — the monitor flips a goal to done with `goal_met` only after it checks the worker's claim against cited proof; an unproven claim is surfaced as `blocked` or `goal_failed`, not accepted. * **Added:** quiet monitor passes leave a dim **check-in** row (`no change · reviewed N events`) so the feed shows the monitor is watching without inventing progress. * **Scope:** this covers one goal run. Multi-goal portfolio rollups, ETA / progress-per-hour, and pause-before-irreversible are not yet wired. See [Stack Overview](/stack) and the repository [`CHANGELOG.md`](https://github.com/synth-laboratories/stack/blob/main/CHANGELOG.md). **Stack nightly channel planning** — release lifecycle, local-first activation, terminal auth, and handoff launch bar. * **Planned:** Stack will use separate `dev/nightly`, release-candidate, and stable channels. * **Added planning surface:** `stack doctor`, `stack demo`, and read-only `stack update --check` are the first local support, receipt, and manifest proof commands for Nightly 1. * **Planned:** local Stack should run without Synth signup; Synth sign-in will unlock hosted features. * **Planned:** public changelog entries will stay user-facing, while private evidence and launch gates remain in internal release ledgers. * **Docs (planning):** [Overview](/stack), [Quickstart](/stack/quickstart). * **Current status:** Stack is still internal alpha. Public package-manager installation and stable support expectations will be added when those channels are live. See [Stack Overview](/stack) and the repository [`CHANGELOG.md`](https://github.com/synth-laboratories/stack/blob/main/CHANGELOG.md). **Stack `0.1.0` internal alpha** — first distributable Stack release for Synth operators. * **Added:** OpenTUI cockpit with Codex agent pane, session history, transcript tooling, and environment-aware Synth operations. * **Added:** `stack-mcp` for local agent access to configured Synth operations. * **Added:** local GEPA and dev-slot setup helpers for internal Synth research engineering workflows. * **Added:** bundled Codex skills for Stack setup, Synth workflows, and Stack agent bridge usage. * **Docs:** [Overview](/stack), [Hosted inference](/stack/inference), [Optimizers (GEPA)](/stack/optimizers). * **Status:** internal alpha only. Public GitHub Release and Homebrew install paths are not live yet.
