 ## [Unreleased]
 
+### Added
+- Added optional `bitcoin` feature flag that implements `Deref<Target = bitcoin::Script>` for `ScriptPubkey` and `ScriptPubkeyRef`, giving kernel script types the full `bitcoin::Script` API transparently.
+
 ### Changed
 - The `verify` function's `flags` parameter now uses `ScriptVerificationFlags` instead of `u32`, making the type explicit in the public API.
