 - The `podman machine init` command now supports a new VM type, `wsl`, available only on Windows; this uses WSL as a backend for `podman machine`, instead of creating a separate VM and managing it via QEMU ([#12503](https://github.com/containers/podman/pull/12503)).
 - The `podman machine init` command now supports a new option, `--now`, to start the VM immediately after creating it.
 - The `podman machine init` command now supports a new option, `--volume`, to mount contents from the host into the created virtual machine.
+- Virtual machines created by `podman machine` now automatically mount the Podman API socket to the host, so consumers of the Podman or Docker APIs can use them directly from the host machine ([#11462](https://github.com/containers/podman/issues/11462)).
 - Virtual machines created by `podman machine` now automatically mount certificates from the host's keychain into the virtual machine ([#11507](https://github.com/containers/podman/issues/11507)).
 - Virtual machines created by `podman machine` now automatically propagate standard proxy environment variables from the host into the virtual machine, including copying any required certificates from `SSL_FILE_CERT` into the VM.
 - The `podman machine ssh` command now supports a new option, `--username`, to specify the username to connect to the VM with.

 - Fixed a bug where the remote Podman client's `--secret` option to the `podman build` command was nonfunctional.
-- Fixed a bug where the remote Podman client's `podman build` command would error if given a relative path to a Containerfile ([#12841](https://github.com/containers/podman/issues/12841)).
