OpenClaw v2026.6.35: Safer provider and channel boundaries, upgrade notes

v2026.6.35 arrived on 2026-09-10 with a change that matters during maintenance: safer provider and channel boundaries. The page is a researched reading note from the official release record, with a test path for a real Gateway.

The tag is stable, but the direct notes still define its migrations, corrections, and package-specific limits. Support still depends on the provider, channel, platform, and account behind the installation, so check those boundaries before extrapolating from the tag.

Before the package changes

Safer provider and channel boundaries

What changed. bundled providers and channel adapters now bound untrusted response bodies, reject oversized inputs before expensive work, and preserve safe recovery when transports fail.

Check it with. The useful evidence for Safer provider and channel boundaries is the refusal path as well as the success path. Use synthetic credentials and record the policy that made each decision.

More reliable long-running delivery

What changed. agent, gateway, retry, and channel paths now handle cancellation, retries, partial sends, and process-stream failures without losing work or replaying unsafe operations.

Check it with. For More reliable long-running delivery, delivery is only proven when identity survives an interruption. Keep a disposable channel, send one request, and check for a single reply in the intended thread.

Stronger bundled-plugin resilience

What changed. local-model, browser, media, and collaboration plugins recover cleanly from malformed payloads, timeouts, and transient upstream failures.

Check it with. The safe reading of Stronger bundled-plugin resilience is operational: prove the model can answer the intended task, then force a bounded failure and verify that no side effect is repeated.

Safer tool and workspace use

What changed. browser automation, local tools, workspace reads, and plugin metadata handling now reject malformed or oversized inputs before they can interrupt an active agent run.

Check it with. A successful click does not establish Safer tool and workspace use. Compare the state before and after a reload, then verify that a user can tell what happened without reading internal logs.

Details behind the headline

More dependable local integrations

local-model discovery, speech, meeting, and collaboration integrations now make bounded requests and surface failures without destabilizing the gateway.

More dependable local integrations changes a capability choice, not automatically a billing or privacy agreement. Record provider, model id, context setting, and fallback behavior before changing a default.

Extended-stable maintenance

this release carries the audited reliability and security backports selected for the extended-stable line, without introducing a new release-line feature.

The useful evidence for Extended-stable maintenance is the refusal path as well as the success path. Use synthetic credentials and record the policy that made each decision.

Response and memory safety

provider, search, embedding, media, and channel integrations cap successful and error response reads before hostile payloads can exhaust process memory.

The operator question around Response and memory safety is where the reply lands after a restart. Record the conversation identifiers before testing and compare them after the channel is healthy again.

Test this release without widening the boundary

1. Note the current version, host, provider, and workspace before exercising Safer provider and channel boundaries.
2. Keep a tested backup beside the release record if the update can touch configuration, sessions, or a database.
3. Send one harmless message through the named account and save the account, thread, and sender identifiers.
4. Compare the transcript before and after reconnect, including delivery state and any visible error.
5. Stop if the observed behavior falls outside the official note, and link the log or screenshot to the version record.

Record what the release actually changed

Keep the version, source URL, test identity, and rollback decision together. If this tag is pre-release, leave it isolated; if it is stable, record the migration and rollback result before reconnecting every channel.

Corrections worth replaying

Response and memory safety. provider, search, embedding, media, and channel integrations cap successful and error response reads before hostile payloads can exhaust process memory. Keep the reproduction and the post-fix result together in the acceptance record.

Delivery and runtime recovery. outbound retry timing, channel lifecycle, abort handling, process I/O, and persisted state recovery now retain the correct operation outcome across expected failures. Record the failure that this correction addresses before declaring the upgrade complete.
