 # Release notes
 
+## v0.187.1
+
+- **Date:** 2026-07-07
+- **Version:** 0.187.1
+
+### Summary
+
+This release improves Dijkstra block compatibility and restores correct validation for genesis staking pool metadata and VRF keys.
+
+### Breaking Changes
+
+* Updated Dijkstra block bodies to the new `Transactions`, `InvalidTransactions`, `LeiosCertificate`, and `PerasCertificate` layout, and applications that read or build Dijkstra blocks must now validate them with `blake2b256(block_body)`.
+
+### Bug Fixes
+
+* Fixed genesis staking pool parsing so Shelley `publicKey`, `vrf`, `owners`, and `metadata` aliases load correctly and pools validate with the expected VRF key hash.
+
+* Improved Dijkstra decoding and encoding so inline transactions, transaction offsets, and Plutus V4 witness script offsets match the reference CDDL.
