 ## [Unreleased]
 
+## [0.15.0] - 2025-03-13
+
+### Added
+
+- Restored support for snark workers.
+- **Archive**: Support for storing blocks to AWS, GCP and filesystem.
+- **Tooling**: WebRTC traffic sniffer.
+- **GraphQL**:
+  - `sendPayment` mutation.
+  - `sendDelegation` mutation.
+  - `pooledUserCommands` query.
+  - `pooledZkappCommands` query.
+  - Various other partially implemented queries expanded to ensure compatibility with the OCaml node.
+
+
+### Changed
+
+- **P2P**: Wait until full validation is complete before broadcasting transactions and completed works.
+- **Transition frontier**: Perform cheap consensus operation first, and then the more expensive proof verification.
+- **Transaction pool**: Unified libp2p and webrtc logic for the initial phase of handling transactions received from gossip network. As a result, processing of transactions received during bootstrap is delayed until the initial sync is complete.
+- **Transaction pool**: Suspend processing during block production.
+
+### Fixed
+
+- **Transition frontier**: Rare race condition in the case of forks during block production that could result in dropping staged ledgers too early.
+- **Webnode**: Replaced tokio channels which had a race condition that could crash the thread on WASM.
+- **Transaction pool**: Verify zkApp proofs in a dedicated thread to avoid blocking the state machine.
