- Support multiple versions of .NET Core (ASP .NET and Console apps)
### Fixed
* Some private registries returning 404 error [#471](https://github.com/Microsoft/vscode-docker/issues/471)
* You shouldn't have to reload vscode in order for changes to docker.attachShellCommand.{linux,windows}Container to take effect [#463](https://github.com/microsoft/vscode-docker/issues/463)
* Add preview support for connecting to private registries
* Improved workflow for Tag Image:
- User will be asked on the first usage of Tag Image with a registry to save it to the `docker.defaultRegistryPath` setting
- User will be prompted to tag an image if attempting to push an image with no registry or username
- New `Set as Default Registry Path` menu on registries
- When default registry path is prefixed to the image name, it is selected for easy removal or editing
* Improved workflow for Build Image:
- Previous image name will be remembered
* Azure container registries can now be browsed without having "Admin user" turned on. However, deploying to Azure app service currently still requires it, and you still need to log in to Azure in docker [#359](https://github.com/Microsoft/vscode-docker/issues/359)
* A new [API](docs\api.md) has been added for other extensions to be able to control the "Add Docker Files to Workspace" functionality.
* You can now create and delete Azure (ACR) registries and delete Azure repositories and images directly from the extension.
### Fixed
* Images list does not refresh after tagging an image [#371](https://github.com/Microsoft/vscode-docker/issues/371)
* Don't prompt for Dockerfile if only one in project (command palette->Build Image) [#377](https://github.com/Microsoft/vscode-docker/issues/377)
* Docker Hub repos are not alphabetized consistently [#410](https://github.com/Microsoft/vscode-docker/issues/410)
* Obsolete usage of `go-wrapper` removed from Go Dockerfile (thanks @korservick)
* Error when listing Azure Registries when some of the accounts do not have appropriate permissions (thanks @estebanreyl) [#336](https://github.com/Microsoft/vscode-docker/issues/336)
* UDP exposed ports not launching correctly [#284](https://github.com/Microsoft/vscode-docker/issues/284)
* Adopt version 0.0.19 of the language server (thanks @rcjsuen) [#392](https://github.com/Microsoft/vscode-docker/pull/392). This fix includes:
- Folding support for comments
- Fix for [#338 Multi-line LABEL directives highlight as errors](https://github.com/Microsoft/vscode-docker/issues/338)
- Support for handling SCTP ports in EXPOSE instructions per Docker CE 18.03
- Optional warning/error for WORKDIR instructions that are not absolute paths (to try to enforce good practices per the official guidelines and recommendations document for Dockerfiles
- New `docker.languageserver.diagnostics.instructionWorkdirRelative` configuration setting
* Output title corrected [#428](https://github.com/Microsoft/vscode-docker/pull/428)
### Changed
* The `docker.defaultRegistry` setting is now obsolete. Instead of using a combination of `docker.defaultRegistry` and `docker.defaultRegistryPath`, now simply use `docker.defaultRegistryPath`. This will be suggested automatically the first time the extension is run.
* Update to version 0.0.18 of the language server (thanks @rcjsuen) [#291](https://github.com/Microsoft/vscode-docker/pull/291). This includes fixes for:
* Auto-complete/intellisense types too much - it repeats what's already written [#277](https://github.com/Microsoft/vscode-docker/issues/277)
* Dockerfile linting error in FROM [#269](https://github.com/Microsoft/vscode-docker/issues/269), [#280](https://github.com/Microsoft/vscode-docker/issues/280), [#288](https://github.com/Microsoft/vscode-docker/issues/288), and others
* Update Linux post-install link in README.md (thanks @gregvanl) [#275](https://github.com/Microsoft/vscode-docker/pull/275)
* Add docker.host setting as alternative for setting DOCKER_HOST environment variable (thanks @tfenster) [#304](https://github.com/Microsoft/vscode-docker/pull/304)
* Basic Dockerfile for Ruby (thanks @MiguelSavignano) [#276](https://github.com/Microsoft/vscode-docker/pull/276)
* Add link to extension docs and Azure publish tutorial to readme
* Fix [#295](https://github.com/Microsoft/vscode-docker/issues/295) to provide proper error handling if project file can't be found adding Dockerfile to project
* Fix [#302](https://github.com/Microsoft/vscode-docker/issues/302) so that Compose Up/Down work correctly from the text editor context menu
* Clarify README documentation on DOCKER_HOST to note that DOCKER_CER_PATH may be required for TLS (thanks @mikepatrick) [#324](https://github.com/Microsoft/vscode-docker/pull/324)
* Support for multi-select of `docker-compose` files and then issuing the `compose up` or `compose down` commands.
* Changed the default of `promptOnSystemPrune` setting to `true`, meaning you will get a confirmation when running the `System Prune` prune command by default. You can change this by setting `docker.promptOnSystemPrune: false` in your `settings.json`. Thanks to [@driskell](https://github.com/driskell) for [PR #213](https://github.com/Microsoft/vscode-docker/pull/213).
* Right click commands on `dockerfile` and `docker-compose.yml` files are now enabled based on a regular expression over the file name rather than being hard coded.
* Fixes [#200](https://github.com/Microsoft/vscode-docker/issues/200) to provide two new options `dockerComposeBuild` and `dockerComposeDetached` control how `docker-compose` is launched
* Fixes [#208](https://github.com/Microsoft/vscode-docker/issues/208) where an incorrect repository name was being passed to Azure App Services
* Update to `v0.0.13` of the Docker Language Server (thanks @rcjsuen) [#198](https://github.com/Microsoft/vscode-docker/pull/198)
* Add `compose up` and `compose down` context menus for files explicitly named `docker-compose.yml` or `docker-compose.debug.yml`
* Browse to the Azure portal context menu, fixes [#151](https://github.com/Microsoft/vscode-docker/issues/151)
* Add `docker.truncateLongRegistryPaths` and `docker.truncateMaxLength` configuration options enable truncation of long image and container names in the Explorer, fixes [#180](https://github.com/Microsoft/vscode-docker/issues/180)
* Images in the Explorer now show age (e.g. '22 days ago')
* Update `docker-compose.debug.yml` command to include full the URI to the debug port (fix for [vscode: 36192](https://github.com/Microsoft/vscode/issues/36192))
* Filter the subscriptions presented when deploying to Azure based on the Azure Account subscription filter
* Support for `.yaml` file extension on `docker-compose` files.
* Updated Azure CLI image name, map .azure folder from host file system, fix block running on Windows containers, fix Windows path issues (this didn't make it into `0.0.12`)
* Added telemetry to understand which commands developers find useful. This will help us refine which commands we add in the future. We track whether the following commands are executed:
*`open shell` on running container and whether or not it is a Windows or Linux based container
*`push image` (we don't track the image name or the location)
*`remove image`
*`show logs`
*`start container`, `start container interactive`
*`start Azure CLI` container
*`stop container`
*`system prune`
*`tag` (we don't track tag name)
* Configure workspace along with the type (e.g. Node or Other)
> Please note, you can turn off telemetry reporting for VS Code and all extensions through the ["telemetry.enableTelemetry": false setting](https://code.visualstudio.com/docs/supporting/faq#_how-to-disable-telemetry-reporting).
* Removed `MAINTAINER` from templates and linting warnings by upgrading the `dockerfile_lint` module (Docker has deprecated `MAINTAINER` in favor of `LABEL`).
* Added command to run `docker system prune`, note we use the `-f` (force) flag to ignore the confirmation prompt.
*`Docker: Attach Shell` command now supports Windows containers [#58](https://github.com/microsoft/vscode-docker/pull/58).
