This release fixes a problem that should not have lasted this long: image generation was powerful in theory and too fiddly in practice.

As of April 24, 2026, OpenClaw can send openai/gpt-image-2 through Codex OAuth without making you also wire up an OPENAI_API_KEY. OpenRouter image models now work through the same image_generate path. Reference-image edits got repaired. And long image runs can ask for more time without you changing global settings.

If you use OpenClaw for media, design drafts, screenshots, or bot-generated images, this is a real upgrade. If you do not, there is still plenty here: Codex chats are less brittle, WebChat finally shows real provider errors, and several security fixes close off ugly edge cases.

🖼️ The biggest practical change: image generation is much easier to trust

The headline item is simple. If you already authenticated with OpenAI Codex, OpenClaw can now use gpt-image-2 without demanding a separate OpenAI API key just for image work.

That matters because a lot of setups were half-configured in a frustrating way. Text worked. Coding worked. Then the first image request fell over because image auth took a different path. This release closes that gap.

OpenRouter image generation also lands on the same tool path. If you prefer OpenRouter for model access or account management, you can now keep image work there instead of treating it as a special case.

Reference-image editing also got a real repair. OpenClaw now sends image edits as multipart uploads again, which means multi-reference edits stop breaking in the exact kind of workflow where you are already juggling enough moving pieces.

What users can do now

• Generate images with openai/gpt-image-2 after Codex login. No extra API-key detour.
• Use OpenRouter image models through image_generate. Same tool, less weirdness.
• Ask for output hints that actually matter. Quality, output format, and OpenAI-specific options like background and compression now pass through cleanly.
• Let a single long image or media job run longer. Per-call timeoutMs support means you do not have to loosen timeouts for everything just because one request is heavy.

🤖 Subagents get a more useful middle ground

sessions_spawn now supports optional forked context for native subagents. That is the right shape for this feature.

Clean isolated child sessions stay the default. Good. But when a child actually needs the parent transcript, you can pass it on deliberately instead of rebuilding context by hand or pretending the child should guess.

If you use subagents for coding, triage, or content work, this makes delegation less awkward without turning every child session into a full copy of the parent by accident.

💬 Codex chat flows stop dropping the ball as often

Several fixes in this release land in the same category: the model did something reasonable, but the surrounding plumbing made it look broken.

• Native Codex follow-up questions go back to the right chat. If Codex asks for input, that prompt now returns to the originating conversation instead of wandering off.
• Windows Codex setups get less stupid. codex.cmd shims are now resolved through PATHEXT, so Windows users are less likely to get stuck on a path detail.
• Codex model metadata is more stable. Manually added Codex models keep the right routing and auth behavior, and the missing openai-codex/gpt-5.5 row gets synthesized when discovery drops it.

None of that is flashy. All of it saves time.

📱 Chat surfaces got less embarrassing

The fix list here is better than it looks.

WebChat now shows hard provider failures like billing, auth, and rate-limit problems instead of leaving you staring at a blank UI. Telegram can turn markdown image syntax into actual outbound media again. Slack group DMs stop leaking internal “Working…” traces into rooms. WhatsApp media handling is more consistent. Assistant-generated images persist in Control UI history instead of vanishing on reload.

These are the kinds of bugs that make a system feel unreliable even when the model did its job. Fixing them matters because users judge the whole product, not the boundary between model and transport.

🔒 There is a lot of security work in here too

This release also tightens approvals, pairing, webhook secrets, Discord policy enforcement, MCP tool exposure, Android intent handling, Teams token checks, and several plugin setup paths.

You do not need to memorize that list. The practical point is simple: if your OpenClaw instance talks to outside networks, mobile clients, channels, or plugins, this is not a release to sit on for two weeks.

What got safer or less annoying

• Duplicate and missing reply cases keep shrinking. Block streaming no longer repeats final text after partial delivery aborts.
• Dreaming is no longer tied to heartbeat timing. Managed dreaming now runs as its own isolated lightweight turn, which is a cleaner design and less fragile in quiet setups.
• Image understanding respects explicit image-model config. Text-only primary models no longer quietly sabotage image inspection when you already told OpenClaw which image path to use.
• WebChat preserves image attachments for text-only models. That means tools can still inspect the original file instead of losing it on the floor.

What I would test right after updating

1. Run one image_generate job with your real setup. If you use Codex OAuth, test openai/gpt-image-2. If you use OpenRouter, test your preferred image model there.
2. Try one reference-image edit. Use the exact workflow that used to fail, especially if you pass more than one reference image.
3. If you use Codex regularly, trigger a follow-up prompt. Confirm the request for user input comes back to the same chat.
4. Open WebChat and force one known error. A missing key or bad model choice is enough. Make sure the UI shows a real error now.
5. If you run Slack, Telegram, or WhatsApp, send one live media test. Do not assume your normal path is fine just because text replies work.

Should you update now?

Yes if you use image generation, Codex, WebChat, or any channel where reply routing mistakes turn into user-facing confusion.

Also yes if your install is exposed to outside input. The security list is long enough that there is no good argument for waiting.

This release does not try to impress you with one giant showpiece. It fixes a bunch of places where OpenClaw was making users work too hard for things that should have just worked.

That is usually the kind of release you feel the next morning.
