Since ports 443 and 8443 are often https, VS Code will now default them to use https. This can be overridden with the "remote.portsAttributes" setting if the new behavior is not wanted.
DNS names can now be specified when forwarding a port. For example, if you have a MongoDB database available at db:1234 on your remote, you can enter "db:1234" in the Ports view and your remote db:1234 will be available locally at localhost:1234. For remotes with a devcontainer.json, you can also specify the DNS name in forwardPorts:
{
"forwardPorts": [ "db:5432" ]
}Forwarded ports that include a non-localhost DNS name show the name in the Ports view:
Many of the dev container definitions now support adding tools and languages as easy to drop-in features. The Dev Containers: Add Dev Container Configuration Files... command at the end shows the list of available features and the Dev Containers: Configure Container Features command allows you to update an existing configuration.
There is also support for IntelliSense to edit the new "features" property in the devcontainer.json directly.
On Windows, to support having Docker CE or Podman installed in Windows Subsystem for Linux (WSL), the new Execute in WSL (dev.containers.executeInWSL) user setting lets the Dev Containers extension run all CLI commands in WSL.
When not enabled, CLI commands are still run in WSL for workspace folders on a WSL filesystem.
