SMI Release

A release represents a Git tag in semver format, cut from the main branch of an SMI rrepository. Each API spec is adresable when refereced outside the SMI repo in the format: <smi-spec-repo>/blob/<semver>/apis/<kind>/<version>/<kind>.md e.g. https://github.com/servicemeshinterface/smi-spec/blob/v0.5.0/apis/traffic-split/v1alpha3/traffic-split.md

Changes to the spec are made by opening pull requests against the draft branch. Before a release, the desired changes, for the next version, are merged from draft into main.

SMI spec release steps:

• Open a pull request from draft into main
