Docker 4.86.0
OK so Docker Desktop 4.86.0 just dropped (August 10, 2026) and I spent the morning poking at it so you don't have to. TL;DR: it's a "boring" release in the best way — no giant new logo, no forced sign-in wall, just a bunch of fixes that make the thing stop doing that thing where it randomly falls over. Let's dig in.
What's Inside the Box
Version 4.86.0 rolls in fresh versions of the usual suspects:
- Docker Engine v29.7.2 — the daemon gets its monthly odds-and-ends update.
- Docker Buildx v0.36.0 — new buildx, new build speeds (allegedly).
- Docker Scout CLI v1.24.0 — because you should be scanning your images, and now the CLI keeps up.
- Docker Agent v1.119.0 — the agent that does agent things.
The Fixes That Actually Matter
Here's where it gets real. I've personally been bitten by two of these:
- Container stop timeouts were being ignored during engine shutdown, and
unless-stoppedrestart policies were straight-up not honored when Docker went down. That's the "why is my container gone after a reboot" bug — and it's fixed. - Docker Offload failed to enable from the Dashboard if your proxy was set by the OS rather than by environment variables. So if you set your proxy in system settings like a normal person, this release finally stops pretending you don't exist.
- Crash on startup after upgrading — for users whose settings file was written by a very old version of Docker Desktop. You know who you are. You can finally upgrade without the ritual.
- Port forwarding for Swarm services that use automatically assigned published ports — fixed, because Swarm users exist and deserve nice things.
The Cool Kid Feature Nobody's Talking About
The Docker VMM Beta — Docker's own container-optimized hypervisor — gets performance improvements on Mac and Windows. It's still beta, so don't bet your production machine on it yet, but the trajectory is good. If you're on Apple silicon and you've been eyeing that VMM toggle in settings, this is a decent time to try it again.
Gordon Got a Braincell
Docker's AI sidekick Gordon now shows specific error messages for tool failures, policy-blocked actions, and loop detection, instead of the generic "Agent error" that told you absolutely nothing. Progress.
Verdict
Update now, especially if you've hit the restart-policy or proxy issues — those two alone are worth the download. Everything else is the usual monthly polish. 8/10, would restart daemon again.
