Description
The following are release dates and EOL / end of support dates for languages / OS's with pre-built images. After runtime or OS support for a given image has ended, we will stop building images for that version. We also typically only release images for "LTS" or "stable" releases of runtimes/OS's. Others can be built from the Dockerfiles available for each image in the source code in this repository.
Releases typically happen monthly, in the final week of one month or first week of the next, and include the most recent changes from the upstream base image or runtime version, including security updates (e.g. the latest OS updates and the latest point release of a runtime or platform). We may update earlier if a critical issue or bug is discovered.
Dev container images are also versioned independent of the runtime. To avoid unexpected breaks, we recommend pinning to the latest major version of an image release to pick up security and feature updates without breaking changes. This image version number is a prefix to the variant or runtime version, e.g. mcr.microsoft.com/devcontainers/typescript-node:0-14 where 0 is the major version number of the dev container image.
To make pinning to a version easier if you wish to do so, recent versions of images include a devcontainer-info command that will output information about the image in use including version information and a link to a file with additional information on contents.
Note: In some cases, we may have to end support earlier than the stated date below if there are fundamental OS requirements that force it or if the primary extension(s) supporting it have dropped support. Our expectation is that this should be rare given typical GA to EOL timelines and is something we strive to avoid.
