 ## Unreleased
 
+## v0.1.0-dev.6
+
+This is a development pre-release.
+
+# Added
+- Implement the `BLOCKHASH` opcode.
+- Implement delegate calls.
+- Implement the `GASPRICE` opcode. Currently hard-coded to return `1`.
+- The ELF shared object contract artifact is dumped into the debug output directory.
+- Initial support for emitting debug info (opt in via the `-g` flag)
+
+# Changed
+- resolc now emits 64bit PolkaVM blobs, reducing contract code size and execution time.
+- The RISC-V bit-manipulation target feature (`zbb`) is enabled.
+
+# Fixed
+- Compilation to Wasm (for usage in node and web browsers)
+
+
 ## v0.1.0-dev.5
 
 This is development pre-release.
