## Known Issues
* (Java) Current version of protobuf has a
[bug](https://github.com/protocolbuffers/protobuf/issues/20599) leading to
incompatibilities with clients using older versions of Protobuf ([example
issue](https://github.com/GoogleCloudPlatform/DataflowTemplates/issues/2191)).
This issue has been seen in SpannerIO in particular. Tracked in
[#34452](https://github.com/GoogleCloudPlatform/DataflowTemplates/issues/34452).
+* (Java) Coders that extend CustomCoder (excluding SchemaCoder and RowCoder)
are update incompatible with previous versions of the same transform (Java) on
some runners. This includes PubSubIO's read
([#34933](https://github.com/apache/beam/issues/34933)).
