Docker Desktop 4.5 makes the installed environment easier to identify

An engine version does not fully describe a Docker Desktop installation. Desktop includes host integration and a dashboard as well as the tools used to run containers. Docker Desktop 4.5 makes that distinction more visible by including the installed Desktop version in docker version output. The February 10 release notes pair that change with a consistent application menu across operating systems.

Those changes belong together. One makes the product easier to operate through its graphical controls. The other makes it easier to identify from a terminal. Neither changes the contents of an application image, but both affect how an engineer understands the environment around it. I care about Docker's repeatable build definitions, so I also care about identifying the machinery that interprets and runs them.

A common menu around different hosts

Docker's release announcement explains that the redesigned menu preserves its previous appearance and operation. The implementation aims to provide a consistent experience across operating systems. Docker also reports faster dashboard opening from the menu. The announcement supplies no benchmark methodology, so the useful claim is the intended reduction in the delay between selecting a menu action and reaching its destination.

Preserving familiar controls limits the amount of retraining a menu change requires. A developer trying to reach settings does not need a different conceptual model merely because the implementation behind the menu changed. That is a reasonable design constraint for infrastructure software. Its controls often interrupt another task, such as starting a dependency or investigating a container that failed to launch.

The announcement provides a way to disable the redesign through a features-overrides.json file. After quitting Desktop, the file can contain the following configuration.

{
  "WhaleMenuRedesign": {
    "enabled": false
  }
}

Docker gives the Mac location as ~/Library/Group Containers/group.com.docker/features-overrides.json and the Windows location as %APPDATA%\Docker\features-overrides.json. This is a specific fallback for the menu change. It should not be interpreted as a general configuration interface for the other fixes in the release.

Version reporting gives support a better starting point

The CLI addition makes a routine diagnostic command more useful. An engineer can request version information without opening a separate About window.

docker version

The notes say the output now includes the installed Desktop version. That addition matters because a report about Desktop behavior needs to identify the Desktop package. Reporting only the container engine leaves out the version of the surrounding application. A problem in host integration or the dashboard may depend on that surrounding code.

Version identity also helps distinguish a reproducible application build from a reproducible workstation environment. An image can remain the same while the software connecting it to the host changes. Treating the Desktop version as part of a problem report gives those changes an explicit place in the evidence. It does not prove that Desktop caused the problem, but it removes an ambiguity that otherwise survives an engine-only report.

My preference is for this information to be available where the diagnostic work already happens. A terminal command that identifies the installed package reduces the need to reconstruct the environment from memory or screenshots. It is a small addition with a clear purpose.

Update information stays with the installed application

The dashboard's Software Updates section now contains release highlights. Docker's announcement says it also displays the latest version number and build numbers for the installed and available versions. Manual update checks still show a separate highlights popup in this release. The announcement describes consolidating that interaction as future work, so the present change is the information available inside the dashboard.

This gives a developer a way to connect an update notice with the installed build. Release highlights are more useful when the user can compare them with an identified starting point. An update dialog that describes only the destination leaves the current environment implicit. Including both build identities makes the proposed transition easier to discuss in a support report.

The same announcement lengthens the interval between feedback prompts. A new installation receives its first prompt after 30 days, replacing 14 days. Subsequent rating prompts wait 180 days instead of 90. These are interaction changes rather than container capabilities, but they affect how often Desktop interrupts development. Less frequent prompts also give users longer exposure to the installed product before asking for an assessment.

The package remains an integration problem

The release notes also fix dashboard control of Compose applications when the application was started with a different Compose version. Their example is an application started with V1 and subsequently managed after switching to V2. The dashboard previously failed to stop it. This is a concrete example of why the version of the desktop application matters alongside the version of an individual command.

A container workflow can cross several interfaces during a single session. Starting an application through a CLI and stopping it through the dashboard should refer to the same application. The Compose fix addresses a failure in that coordination. It gives the version-reporting addition a practical context beyond update bookkeeping.

Docker's earlier description of Desktop explains the scope of the package, including its virtual machine and host integration. The February changes make that package easier to identify and control. For engineers who mainly work through build files and terminal commands, the resulting benefit is more precise information about the local environment and fewer inconsistencies when another interface manages the same application.
