+---
+
+Three releases shipped in [github/gh-aw](https://github.com/github/gh-aw) this week, headlined by work queues and built-in ledgers in [v0.90.3](https://github.com/github/gh-aw/releases/tag/v0.90.3). Here's what's new.
+
+## Release Highlights
+
+### [v0.90.3](https://github.com/github/gh-aw/releases/tag/v0.90.3)
+
+This release introduces **work queues and ledgers**, tightens safe-output guardrails, and broadens Copilot model support.
+
+- **Work queue & ledgers**: built-in log, set, map, table, and counter ledgers, plus Git-backed `work-queue` operator commands. See the [ledger compaction docs](https://github.github.com/gh-aw/experimental/ledger-compaction/). Related PRs: [#65494](https://github.com/github/gh-aw/pull/65494) adds selectable issue-backed queue storage, and [#65443](https://github.com/github/gh-aw/pull/65443) dispatches queued work to trusted worker workflows.
+- **Copilot engine**: AWF task-level model routing, `none` and `max` reasoning efforts, GPT-6.1 Sol support, Claude 5.5 and GPT-6 pricing, and a run-wide tool-call budget for Copilot SDK agents.
+- **Safe outputs**: `add-labels` supports separate call and per-call label limits, and several hardening fixes landed. [#65612](https://github.com/github/gh-aw/pull/65612) adds attributed issue creation for custom safe-output jobs.
+- **Docs**: a redesigned site with a new landing page, warm palette, and Mona Sans.
+
+Heads-up on behavior changes: GitHub App tokens now require explicit scopes at compile time, Claude defaults to strict MCP configuration, and `add-comment` fails when the triggering target can't be resolved.
+
+### [v0.90.1](https://github.com/github/gh-aw/releases/tag/v0.90.1)
+
+Standalone safe-output-backed ledgers arrived ([#64354](https://github.com/github/gh-aw/pull/64354)), along with richer audit artifacts covering ledger transactions and threat-detection outcomes ([#64509](https://github.com/github/gh-aw/pull/64509), [#64506](https://github.com/github/gh-aw/pull/64506)), and compile-time self-hosted runner enforcement ([#64173](https://github.com/github/gh-aw/pull/64173)).
+
+### [v0.90.0](https://github.com/github/gh-aw/releases/tag/v0.90.0)
+
+Step summaries now render friction cost, agents may emit two `noop` calls by default ([#64031](https://github.com/github/gh-aw/pull/64031)), and five new trajectory graders were added.
+
+## Other Notable Pull Requests
+
+- [#65423](https://github.com/github/gh-aw/pull/65423) adds a TLA+ workflow security model and fail-closed credential cleanup.
+- [#65564](https://github.com/github/gh-aw/pull/65564) emits incomplete outcomes with diagnostics when an agent produces no safe outputs.
+- [#65650](https://github.com/github/gh-aw/pull/65650) makes PR Sous Chef poll faster and start agents only for actionable work.

+## 🤖 Agent of the Week: daily-arxiv-researcher
+
+A daily scout that reads the latest arXiv papers and looks for ideas that could improve GitHub Agentic Workflows.
+
+Its recent runs have all succeeded in about five to six minutes. The October 2 and 3 runs used the Copilot CLI engine, and the October 4 run was the first on the Codex engine with web search and fetch tools, after a [recent change](https://github.com/github/gh-aw/pull/65383) moved it there. That run used roughly 84K tokens, versus 7K and 13K for the earlier runs.
+
+The new engine is evidently more curious: it read about six times as many tokens as its predecessor on the same morning schedule.
+
+💡 **Usage tip**: Pair a research workflow with a dedup cache, as this one does with `cache-memory`, so it never reports the same paper twice.
