+## Supported Versions
+
+We follow a versioning strategy as defined by [RSpec Rails versioning strategy][] the
+TL;DR of which is that we support currently supported versions of Rails, and will
+issue a major version change when removing older versions from support.
+
+**Note** Rails 7.1 is supported by the Rails team until October 2025, and thus `rspec-rails`
+will support bug fixes for this version in the `7-2-maintenance` branch until that time.
+
+Accordingly you should use:
+
 * **[`rspec-rails` 8.x][]** for Rails 8.0 or 7.2.
 * **[`rspec-rails` 7.x][]** for Rails 7.x.
 * **[`rspec-rails` 6.x][]** for Rails 6.1, 7.0 or 7.1.
