The entry summarizes the merged v0.0.79 release train across inference,
diagnostics, runtime hardening, policies, onboarding recovery, and
release validation.

## Type of Change

- [ ] Code change (feature, bug fix, or refactor)
- [ ] Code change with doc updates
- [x] Doc only (prose changes, no code sample modifications)
- [ ] Doc only (includes code sample changes)

## Quality Gates
<!-- Check exactly one tests line and one docs line. Check other lines
when applicable. Add every requested justification or approval
reference. -->
- [ ] Tests added or updated for changed behavior
- [ ] Existing tests cover changed behavior — justification:
- [x] Tests not applicable — justification: Release-note prose only.
- [x] Docs updated for user-facing behavior changes
- [ ] Docs not applicable — justification:
- [ ] Sensitive paths changed (security, policy, credentials, preflight,
onboarding, inference, runner, sandbox, or messaging)
- [ ] Sensitive-path review completed or maintainer-approved waiver
recorded — reviewer/approval link/justification:
- [ ] Non-success, skipped, or missing CI check accepted by maintainer —
check name, approval link, and follow-up issue:

## Verification
<!-- Check each applicable item only when supported by the requested
evidence. Run targeted tests once per relevant change set and rerun
after later edits or hook autofixes that can affect the tested behavior.
Do not rerun hook-covered checks. -->
- [x] PR description includes the DCO sign-off declaration and every
commit appears as `Verified` in GitHub
- [x] Normal `pre-commit`, `commit-msg`, and `pre-push` hooks passed, or
`npm run check:diff` passed when hooks were skipped or unavailable
- [x] Targeted behavior tests pass for the current change set, or tests
are marked not applicable above — command/result or justification: Tests
not applicable, release-note prose only.
- [ ] Applicable broad gate passed — `npm test` for broad
runtime/test-harness changes; `npm run check` for repo-wide
validation/coverage changes — command/result:
- [x] Quality Gates section completed with required justifications or
waivers
- [x] No secrets, API keys, or credentials committed
- [ ] `npm run docs` builds without warnings (doc changes only)
- [x] Doc pages follow the [style
guide](https://github.com/NVIDIA/NemoClaw/blob/main/docs/CONTRIBUTING.md)
(doc changes only)
- [ ] New doc pages include SPDX header and frontmatter (new pages only)

Docs validation note: `npm run docs:check-agent-variants && npm run
docs:check-routes && git diff --check` passed. Full `npm run docs` is
currently blocked before Fern validation because the pinned
`fern-api@5.65.2` package is unavailable from npm (`ETARGET No matching
version found`).

+## v0.0.79
+
+NemoClaw v0.0.79 expands hosted and local inference options, improves operator diagnostics and shell integration, and hardens sandbox recovery, Deep Agents runtime limits, policy boundaries, and release validation.
+The release also refreshes quickstarts and variant rendering so OpenClaw, Hermes, and LangChain Deep Agents Code readers see only the agent-specific setup paths that apply to them.
+
+- OpenRouter is now a first-class onboarding provider for OpenClaw, Hermes, and LangChain Deep Agents Code.
+  NemoClaw validates `sk-or-` credentials, uses OpenRouter's OpenAI-compatible route through `https://inference.local/v1`, and keeps the OpenRouter catalog independent from NVIDIA Endpoints filtering.
+  For more information, refer to [NemoClaw Inference Options](../inference/inference-options), [Switch Inference Providers](../inference/switch-inference-providers), and [Platform Support and Launch Claims](../reference/platform-support).
+- Local and compatible inference setup is more resilient.
+  Managed vLLM starts with argv-safe Docker arguments, DGX Spark uses the Qwen3.6 `qwen3_coder` tool parser, OpenClaw bounds managed inference compaction, and onboarding uses calibrated provider-validation and gateway-readiness deadlines to avoid hanging or failing too early on slower hosts.
+  For more information, refer to [NemoClaw Inference Options](../inference/inference-options), [Use a Local Inference Server](../inference/use-local-inference), and [Troubleshooting](../reference/troubleshooting).
+- CLI and installer diagnostics are easier to act on.
+  The new `$$nemoclaw completion` command generates Bash, Zsh, and Fish completions, structured logging now supports `--debug` and `NEMOCLAW_LOG_LEVEL`, `status` warns when the live gateway route drifts from the recorded sandbox route, and gateway teardown now recommends and runs `openshell gateway remove` consistently across platforms.
+  Installer and uninstall flows also report preserved orphaned sandboxes more honestly, and DGX Spark express installs use the expected `my-assistant` sandbox name.
+  For more information, refer to [NemoClaw CLI Commands Reference](../reference/commands), [Switch Inference Providers](../inference/switch-inference-providers), and [Host Files and State](../reference/host-files-and-state).
+- Runtime and configuration boundaries are tighter.
+  Managed LangChain Deep Agents Code enforces process and file-descriptor limits, accepted OTLP endpoint URLs no longer trip the secret guard, proxy environment exports stay POSIX-compatible, nested OpenShell PID namespaces are recognized by config guards, and TOML config reads and parsing fail closed instead of accepting ambiguous content.
+  Re-onboarding also removes stale registered extra providers so the sandbox state matches the selected provider set.
+  For more information, refer to [Security Best Practices](../security/best-practices), [Credential Storage](../security/credential-storage), [NemoClaw CLI Commands Reference](../reference/commands), and [Quickstart with LangChain Deep Agents Code](/user-guide/deepagents/get-started/quickstart).
+- Network policy and messaging behavior now preserve narrower boundaries.
+  Homebrew Git operations require the GitHub policy preset for Git egress, Gmail has a documented policy preset and integration example, custom URL-based MCP server allowlists are documented, WhatsApp post-pair gateway restarts no longer require `operator.admin`, and the overview hides messaging-channel guidance from Deep Agents pages where the channel flow is not supported.
+  For more information, refer to [Network Policies](../reference/network-policies), [Common Integration Policy Examples](../network-policy/integration-policy-examples), [Customize the Network Policy](../network-policy/customize-network-policy), and [Messaging Channels](/user-guide/openclaw/manage-sandboxes/messaging-channels).
+- Onboarding and recovery paths preserve intent across more interrupted flows.
+  Resume recovery now follows one explicit finite-state path, pending route reservations survive resume, sandbox create-failure reporting is separated from create-step handling, BuildKit progress no longer forces plain output, and null-name resume sessions are covered so canceled or malformed session state does not send users down the wrong recovery path.
+  For more information, refer to [NemoClaw Quickstart with OpenClaw](../get-started/quickstart), [NemoClaw CLI Commands Reference](../reference/commands), [Manage Sandbox Lifecycle](../manage-sandboxes/lifecycle), and [Troubleshooting](../reference/troubleshooting).
+- Documentation and release validation are more deterministic.
+  The docs define extension taxonomy and SDK readiness gates, streamline the agent quickstarts, clarify legacy k3s sandbox resources, preserve list spacing in generated agent-variant pages, and add release-train risk planning with post-merge E2E shadow signals, queued Jetson dispatch guards, TUI idle regression coverage, and reusable live-readiness polling primitives.
+  For more information, refer to [Extension Taxonomy and SDK Readiness](../reference/extension-taxonomy-sdk-readiness), [NemoClaw Quickstart with OpenClaw](../get-started/quickstart), [Architecture Details](../reference/architecture), and the [NemoClaw E2E README](https://github.com/NVIDIA/NemoClaw/blob/main/test/e2e/README.md).
+
 ## v0.0.78
 
 NemoClaw v0.0.78 adds opt-in thread-scoped auto-approval and policy-routed repository reads for managed LangChain Deep Agents Code, authoritative agent-visible inference health, round-trippable policy export, and stronger recovery for local inference, custom images, managed MCP, remote dashboards, and credential capture.
