## 4.78.0

{{< release-date date="2026-06-15" >}}

{{< desktop-install-v2 all=true win_arm_release="Early Access" version="4.78.0" build_path="//" >}}

### Updates

- [Docker Agent v1.73.0](https://github.com/docker/docker-agent/releases/tag/v1.73.0)
- `docker pass` v0.1.4
- [Credential helpers v0.9.8](https://github.com/docker/docker-credential-helpers/releases/tag/v0.9.8)

### Bug fixes and enhancements

#### For all platforms

- Fixed an out-of-memory crash that could cause Docker Desktop to become unresponsive or crash while streaming logs in the Docker Desktop Dashboard.
- Improved Docker Desktop update reliability by retrying stalled and transient download failures and resuming from the partially downloaded file.
- Added live streaming output to the Gordon tool calls so long-running commands like `docker compose up` display STDOUT/STDERR in real time instead of waiting until completion.
- Added color-coded labels to the **Logs** view so each container and build source is visually distinguished by a unique color in both the log grid and the container-filter dropdown.
- Improved error message when the Docker Desktop VM fails to start. It now shows the underlying `VirtualizationFramework` / `libkrun` reason instead of the generic **Use of closed network connection**.
- Fixed a bug where Docker CLI error messages were shown as raw JSON instead of human-readable text while Docker Desktop was in Resource Saver mode.
- Fixed a crash that occurred in the **Logs** view when deselecting a container filter.
- Fixed an issue where the support page was replaced by the no-virtualization override screen when accessed from the troubleshooting popover.
- Fixed an issue where Docker Desktop failed to start on bare metal EC2 instances (e.g. `g4dn.metal`) with a **Nested virtualization not supported** error.
Comment thread
aevesdocker marked this conversation as resolved.
- Increased the retry delay to accommodate transient rename failures caused by antivirus software holding file locks.
- Gordon now shows clear network error messages with guidance to check VPN, proxy, or firewall settings when outbound HTTPS to Docker's services is blocked, instead of a generic agent errror.

[MEDIUM] Typo: 'errror' should be 'error'

The word errror has three r's. This typo appears in user-visible release notes prose: "instead of a generic agent errror." Correct to error.

- Fixed the Gordon AI model picker incorrectly showing an internal model identifier instead of 'Default' for sessions with no explicit model selection.

#### For Windows

- Fixed getting stuck on **Starting the Docker Engine…** after an in-place upgrade.
- Added [Synchronized File Shares](/manuals/desktop/features/synchronized-file-sharing.md) support for the WSL2 backend.
- Fixed a bug where Docker Desktop was not restarted after a failed update was reverted to the previous version.
- Fixed delta updates failing to prepare.
- Fixed an issue on Hyper-V where Docker commands (e.g. `docker login`) would fail on the first attempt after the engine had been idle-shut-down or paused.
- Fixed an issue on Windows where Docker Desktop showed a generic engine-start failure instead of a clear, actionable error message when WSL is not installed.
