 * With xref:security:authorization/gbac/gbac.adoc[GBAC in the control plane], you can manage access to organization-level resources using OIDC groups from your identity provider. Assign OIDC groups to roles so that users inherit access based on their group membership.

 === Increased Serverless limits for Redpanda Connect pipelines and MCP servers
 
 Serverless clusters now support up to 100 Redpanda Connect pipelines and 100 MCP servers. See xref:get-started:cluster-types/serverless.adoc#_serverless_usage_limits[Serverless usage limits].
 
 === Redpanda Connect updates
 
+* The Redpanda Connect pipeline creation and editing workflow has been simplified. The new UI replaces the previous multi-page wizard with a visual pipeline diagram, an IDE-like configuration editor, slash commands for inserting variables, and inline links to component documentation. See the xref:develop:connect/connect-quickstart.adoc[Redpanda Connect quickstart] to try it out.
