This page is maintained and updated periodically to reflect our roadmap and any decisions around feature deprecation.

## Impact
@ -24,3 +25,7 @@ At 2.9, a new plugin catalog home should be available, decoupled from pilot.
Starting on 2.8 the `namespace` option of Consul and Consul Catalog providers is deprecated,
please use the `namespaces` options instead.
### TLS 1.0 and 1.1
Starting on 2.8 the default TLS options will use the minimum version of TLS 1.2. Of course, it can still be overridden with custom configuration.
