A. Older tag versions

Docker images for SDK releases prior to SDK 2.5.0 used a slightly different format for tags.

The main differences are:

• The OS version was indicated by name (for example, bionic) instead of the version number (18.04)

• The build date was the date of the Docker base image, not the date the image was built by Graphcore

• The latest tag did not exist

• The tags for SDK 2.3 include only the version (for example, bionic) and not the distribution name (ubuntu-bionic)

Examples of the tags are shown in Table 3.1.
