+== {DTProductName} 2.8.0 Technology Preview
+
+This release introduces support for {TempoName} as a Technology Preview feature for {DTProductName}.
+The feature uses version 0.1.0 of {TempoName} and version 2.0.1 of the upstream {TempoShortName} components.
+
+You can use {TempoName} to replace Jaeger so that you can use S3-compatible storage instead of ElasticSearch.
+Most users who use {TempoName} instead of Jaeger will not notice any difference in functionality because {TempoShortName} supports the same ingestion and query protocols as Jaeger and uses the same user interface.
+
+If you enable this Technology Preview feature, note the following limitations of the current implementation:
+
+* {TempoName} currently does not support disconnected installations. (link:https://issues.redhat.com/browse/TRACING-3145[TRACING-3145])
+
+* When you use the Jaeger user interface (UI) with {TempoName}, the Jaeger UI lists only services that have sent traces within the last 15 minutes.
+For services that have not sent traces within the last 15 minutes, those traces are still stored even though they are not visible in the Jaeger UI. (link:https://issues.redhat.com/browse/TRACING-3139[TRACING-3139])
+
+Expanded support for the Tempo Operator is planned for future releases of {DTProductName}.
+Possible additional features might include support for TLS authentication, multitenancy, and multiple clusters.
+For more information about the Tempo Operator, see link:https://tempo-operator.netlify.app[the Tempo community documentation].
