Docker 4.87.0

Docker has shipped Docker Desktop 4.87.0, the latest release of its developer platform, rolled out on August 17, 2026. The update lands roughly a week after 4.86.0 and focuses on stability, cross-platform bug fixes, and refreshed bundled tooling rather than headline feature additions.

What Changed

The bulk of this release is a set of targeted fixes across macOS, Windows, and Linux. A recurring theme is the update and diagnostic pipeline, which had several edge cases where upgrades failed or produced misleading errors. On the tooling side, Docker Desktop 4.87.0 ships Docker Agent v1.122.0, Docker Buildx v0.36.1, Docker Offload v0.6.10, Docker Compose v5.4.0, and a Linux kernel bump to v7.0.12.

Why It Matters

For developers, the most visible improvements are around reliability. The in-app update no longer fails with a confusing "Source and destination path must have identical roots" error when Docker Desktop lives on a custom drive, and a stale "file exists" failure after an earlier botched update is now resolved. Proxy errors now name the actual unreachable upstream instead of the destination server, and diagnostics include machine-wide proxy configuration.

Mac users with the libkrun engine should no longer see a false "Docker Desktop encountered an unexpected error" dialog during VM shutdown, and a rare crash with the Apple Virtualization Framework VM right after opening a connection has been fixed. On Windows, WSL error recovery now surfaces specific, actionable messages, and per-user installs write their settings and diagnostics to the correct locations.

What's Next

Docker continues its weekly cadence, and 4.87.0 is available for macOS, Windows, and Linux through the standard in-app update or direct download. As always with Docker Desktop releases, the update rolls out gradually, so it may take up to a week before every machine receives the notification.
