FluentDocker 3.1.0 builds on the v3 rewrite with a batch of fluent-API additions, a couple of correctness fixes, and expanded engine support. All changes ship with unit tests.

✨ Added

• Container Kill — IContainerService.KillAsync(signal = "SIGKILL") for fast, forceful teardown of disposable containers without a graceful stop. (#267)
• Compose Restart — IComposeService.RestartAsync() and RestartAsync(services) to restart a whole project or specific services. (#318)
• Interactive / TTY / entrypoint — WithInteractive(), WithTty() and WithEntrypoint(...) on the container builder, so short-lived images (e.g. SDK images) can be kept alive for ExecuteAsync. (#264)
• In-place image builds — DockerfileBuilder.WithBuildContext(...) builds an existing Dockerfile in place via the engine's --file, so no generated Dockerfile is left in your working directory. (#280)
• Attach to an existing compose project — IComposeBuilder.ConnectToExisting() returns a service bound to a running project without docker compose up, plus IComposeService.RefreshStateAsync() to read its live state. (#305)
• Custom docker-compatible CLI — IDockerCliDriverBuilder.WithBinary("finch" / "nerdctl", ...) drives compatible engines without aliasing them to docker (best-effort). (#315)
• Log source tagging — IStreamDriver.StreamLogEntriesAsync(...) yields LogEntry values tagged with LogStreamSource (stdout/stderr); the Docker Engine API driver reports the real source from the multiplexed stream. (#326)

🔧 Changed

• ExecuteOnRunning / ExecuteOnDisposing now execute each string argument as a separate command (restoring the v2 contract). Running commands fire after wait conditions, exactly once, and command failures surface instead of being silently swallowed. (#283)

🐞 Fixed

• GetConfiguration inspect parsing — the engine returns NetworkSettings.LinkLocalIPv6PrefixLen, GlobalIPv6PrefixLen and IPPrefixLen as JSON numbers; a tolerant string converter prevents the DriverException: Failed to inspect container regression introduced by the move to System.Text.Json. (#335)

📖 Documentation

• Added an "Inspecting Container Info" guide: created date, image config, environment, exposed ports, labels, and the mapped host port. (#197)
