 # Upcoming Starknet versions
 
-## Starknet Alpha v0.12.2
+## Starknet Alpha v0.12.3
 
 [id="what_to_expect"]
 ### What to expect
-The focus of Starknet v0.12.2 is to enhance Starknet's reliability and performance.
+The focus of Starknet v0.12.3 is to deprecate the Starknet feeder gateway.
 
-### Notable changes
+The Starknet feeder gateway serves as a gateway for querying the centralized sequencer on the state of Starknet. It was meant to be used as a temporary solution until full nodes that support Starknet’s JSON-RPC mature and are able to meet the needs of the community.
 
-#### Enabling P2P Authentication
-To establish a secure peer-to-peer network, Starknet is adding an endpoint in the sequencer gateway to provide a signature on the state diff commitment and block hash. This allows nodes to check the integrity of peer’s data and avoid DoS attacks.
+Starknet now has three different full node implementations in production (xref:pathfinder_versions.adoc[Pathfinder], xref:juno_versions.adoc[Juno], and Papyrus). Consequently, it is time to deprecate the feeder gateway and migrate to RPC providers.
 
-#### Resolving Mismatches in Queries
-Starknet is introducing an extension to the `get_state_update` endpoint in the sequencer gateway that returns both the pending state diff and the pending block together. This simplifies the process for full nodes to address discrepancies between pending block and state diff queries.
+#### Key dates
+
+The feeder gateway will stop supporting most queries on the following dates:
