Add release notes for 0.4.3
# Release Notes
+## Changes in Transact 0.4.3
+
+* Alter column type for `merkle_radix_leaf.address` in SQLite. This fixes a bug
+ where address that were valid numeric values would have their leading 0s
+ removed (as expressed in the hex string of the address).
+* Move `CommandTransactionBuilder` from `transact::families::command::workload`
+ to `transact::families::command`. The original version remains and is now
+ deprecated.
+* Update rustdoc for transact::state::merkle module with more detail
+* Update rustdoc for transact::state::Prune trait for clarity
