+# SDK Release Notes
+
+This file is the canonical release notes ledger for Switchboard SDK releases.
+The newest release batch should stay at the top.
+
+## 2026-06-08 Release Prep
+
+### `@switchboard-xyz/on-demand@3.10.4`
+
+Status: prepared; dry-run verified.
+
+- Fixed Solana network resolution so official Switchboard program IDs resolve to the correct cluster defaults.
+- Fixed randomness oracle eligibility so healthy pull oracles are not rejected only because `enable_gateway = 0`; `enable_pull_oracle` remains the relevant eligibility gate.
+- Includes the merged `sbv3#1015` randomness eligibility fix and smoke-test coverage.
+
+### `switchboard-on-demand-client@0.6.0`
+
+Status: prepared; dry-run verified.
+
+- Updated the client crate for Solana 3.x crate compatibility.
+- Fixed release guardrail paths so crate packaging checks use the `solana/rust/switchboard-on-demand-client` mirror layout.
+
+### `switchboard-on-demand@0.12.2`
+
+Status: prepared; dry-run verified.
+
+- Preserved Crossbar feed simulation results when building update instructions.
+- Fixed Sui result deserialization and removed noisy client logs.
+- Kept the SBF-safe `libsecp256k1` feature split for Solana builds.
