If the process boots cleanly on 2026.3.8, can operators assume the upgrade is healthy?

No. A clean boot only proves the service starts. Operators still need to verify the real traffic path, especially inbound channel delivery, the exact production model id, and one successful end-to-end agent run before treating the upgrade as healthy.

What is the single fastest way to catch a bad 2026.3.8 rollout before users feel it?

Run one symptom-based smoke path instead of generic status checks: send one real inbound message, make one production model request, and finish one critical agent task. That sequence surfaces the most damaging upgrade regressions faster than only checking logs or startup success.

When should operators stop debugging and reduce exposure first?

If your main inbound path, model routing, or tool callback flow is still failing after initial isolation, reduce exposure before continuing deep debugging. For a growth property, protecting high-intent traffic paths is more important than forcing the same rollout to succeed immediately.

OpenClaw 2026.3.8 Release: Changelog + Known Issues Guide (Maintained)

This is a maintained release index for 2026.3.8: it links to the official changelog and consolidates the most common post-upgrade issues into fast troubleshooting paths.

Official GitHub Release notes: https://github.com/openclaw/openclaw/releases/tag/v2026.3.8

Basic upgrade checklist

Back up your Gateway config/state first; if you have a staging Gateway, validate there before production.
Right after the upgrade, do a quick regression check: your primary inbound channel + one critical agent end-to-end.

Who should read this upgrade page first

This maintained page is especially useful for three groups:

operators jumping directly from an older build to 2026.3.8, because they need a “what do I check first after the upgrade” hub, not just raw release notes.
teams whose main paths depend on Discord or Google / Gemini, because the highest-frequency known issues for this release cluster around those lines.
people covering upgrade duty for a shared Gateway, because this page compresses “read the release notes, then branch into the right troubleshooting page” into one handoff point.

Fast symptom split after upgrading to 2026.3.8

If your first reaction after the upgrade is that “OpenClaw feels unstable everywhere”, do not keep every symptom bundled together. Split it fast:

DMs work, but server channel messages never arrive
- go straight to the Discord guild-message troubleshooting path.
Google / Gemini calls all start failing with 404s
- prioritize model-id mapping and version pin / rollback checks.
You do not have a clear error yet and only want to reduce rollout risk
- run one inbound-channel regression plus one critical agent regression before widening exposure.

That triage pattern helps teams avoid labeling 2026.3.8 as a blanket failure when the real problem may be a narrower post-upgrade regression.

Common issues after upgrading to 2026.3.8 (quick links)

1) Discord: DMs work, but guild/channel messages never reach the Gateway

If DMs are fine but messages sent in a server channel don’t show up in your Gateway logs / don’t trigger anything, follow this checklist (allowlist / requireMention / intents / practical mitigations):

“OpenClaw 2026.3.8: Discord Guild Messages Missing in Gateway (Symptoms, Checks, Workarounds)”
- /en/news/discord-guild-message-create-missing-2026-3-8

2) Google / Gemini: the OpenAI-compatible endpoint returns 404 NOT_FOUND

If your error includes models/google/gemini-* is not found, the usual unblocks are “ensure the model id sent to Google is unprefixed” or temporarily pin/downgrade until upstream fixes it:

FAQ: what operators usually ask after a 2026.3.8 upgrade

Is 2026.3.8 safe to deploy if I mainly use Discord?

Yes, but do not treat the release notes alone as your go-live checklist. If Discord is a primary inbound path, verify one real guild-channel message and one DM after the upgrade. That single split tells you whether the risk is broad or isolated to guild-message handling.

We only use Google or Gemini models. What should we validate first?

Run one live request against the exact production model ids you intend to keep. If you see a sudden 404 NOT_FOUND, do not keep testing random prompts. Check whether the outgoing model id is being sent with an unexpected prefix, then decide whether to pin, roll back, or apply the known workaround.

What is the fastest rollback trigger for an upgrade window?

If your main inbound channel fails its first end-to-end regression and you do not have a narrow fix within the same maintenance window, roll back. The goal is to protect the traffic path, not to prove the new build can eventually be stabilized under pressure.

Upgrade-window fast decision tree

Use this when you need to decide in minutes whether 2026.3.8 is healthy enough to keep exposed:

Inbound channel broken for real traffic
- Treat that as a rollout risk first, not as a documentation problem.
- Verify whether the failure is limited to Discord guild messages or affects all inbound paths.
Model calls fail but inbound still works
- Check the exact production model id before changing prompts or API keys.
- If the break is isolated to Google / Gemini 404s, route straight to the model-specific troubleshooting page.
Inbound and model calls both look healthy
- Run one real agent task before calling the upgrade stable.
- If the agent path also passes, you can usually widen exposure with lower risk.

What to verify before calling the upgrade stable

Before you close the maintenance window, confirm all three are true:

one real inbound message reached the Gateway through the production path;
one real production model request completed with the intended provider and model id;
one critical agent task finished end to end without tool-return or session continuity regressions.

That closing check is usually faster and safer than treating process startup as proof that the release is healthy.

Search-intent takeaway for operators evaluating OpenClaw 2026.3.8

If users land here from search, they are usually trying to answer a practical rollout question, not browse a generic changelog. They want to know whether 2026.3.8 is safe enough to upgrade, whether their current symptom is more likely tied to Discord guild ingress, Google or Gemini model routing, or broader rollout validation, and which check should happen first before they widen exposure.

FAQ: upgrade checks operators most often skip

If 2026.3.8 looks fine at a glance, do I still need extra checks?

Yes. Run at least one real inbound regression and one real agent execution. “No obvious error” is not the same as “the traffic path is healthy”, especially when regressions only surface on guild inbound, model routing, or tool callback flows.

What is the single best reminder to put at the top of an internal upgrade SOP?

Put symptom-based branching first. Decide whether you are looking at Discord guild ingress failure, Google / Gemini 404s, or only general rollout uncertainty, then jump to the matching troubleshooting page. That reduces wasted search time during an upgrade window.

When should I stop debugging and reduce exposure first?

If your main inbound path is failing reproducibly and you still cannot narrow the failure surface to one component within roughly 15 to 30 minutes, reduce traffic or pause the rollout first. For a growth site, protecting high-intent entry paths matters more than forcing a fix during the same window.

Fast upgrade-window checklist

If you want to use this page as an operator handoff hub, run through this order:

Open the official release notes and confirm the exact version you are about to roll out.
Send one real test message through each critical channel and confirm inbound delivery.
Run one minimal request with the exact production model id to catch Google / Gemini 404s early.
Let one critical agent finish a real run so tool calls and returns are verified.
If any step fails, record the symptom and branch into the matching troubleshooting page instead of continuing a blind rollout.

FAQ: if 2026.3.8 seems healthy, what is still worth validating?

If Discord guild messages and DMs both work, can I close the upgrade window?

Not yet. A safer closeout is to run one real execution of your most business-critical agent. On 2026.3.8-style regressions, inbound recovery does not guarantee model routing, tool callbacks, or session continuity are also healthy.

When should I treat 2026.3.8 as a localized regression instead of a whole-site failure?

Treat it as localized when the problem narrows cleanly to one path, for example only Discord guild ingress fails, or only Google / Gemini requests return 404 while home page traffic, DMs, and other providers still work. That is the point where faster isolation beats broad rollback language.

What are the three most useful handoff notes for the next operator?

Write down these three items first:

Which primary traffic path is affected, for example guild ingress, Google model calls, or agent execution.
One minimal reproduction path, instead of a vague note like “the upgrade feels unstable”.
Which paths you have already verified still work, so the next operator does not restart from zero.

Those three notes cut duplicated debugging and help protect high-intent entry points during the same maintenance window.

Operator incident note template for 2026.3.8

When this release page is used during a live upgrade, copy a short note before handing off: version promoted, channels tested, provider and model id tested, agent task tested, failing symptom, rollback decision, and the next owner. That gives the next operator enough context to decide whether the page should branch into Discord ingress, Google / Gemini 404s, or general agent troubleshooting.

A useful note is only five lines long: current version, affected entry path, exact reproduction, last known good config, and current mitigation. Anything longer tends to hide the decision that protects the traffic path.
