+
+A new release of BDK is out: [`v0.8.0`] brings new APIs and other minor bugfixes and internal improvements.
+
+You can find the full [v0.8.0 changelog][changelog] on GitHub.
+
+## What's new in v0.8.0
+
+Below are some highlights of the new release:
+
+### Getting the Derivation Index
+
+The `Wallet::get_address()` method now returns an [`AddressInfo`] structure, rather than a simple `Address`. This new structure contains the address but also the derivation index, which can be useful in some contexts.
+
+Since the structure implements `Deref<Target=Address>` it can be used directly as a `&Address`, which simplifies migrating to this change a little bit.
+
+```rust
+let address_info = wallet.get_address(AddressInfo::New)?;
+
+// Print the address and derivation index
+println!("Address #{}: {}", address_info.index, address_info.address);
+
+// Use the `AddressInfo` structure directly like an `Address`
+let script_pubkey = address_info.script_pubkey();
+```
+
+### Explicitly Enable non-ALL Sighashes
+
+To mitigate potential attacks in multiparty protocols, this release includes a new [`SignOptions::allow_all_sighashes`][sign_option] option that must be explicitly enabled to let the signers produce signatures
+with any non-ALL sighash.
+
+```rust
+let mut psbt = ...;
+
+// Fails if the psbt uses non-ALL sighashes
+let finalized = wallet.sign(&mut psbt, SignOptions::default())?;
+
+// Produces a signature successfully
+let finalized = wallet.sign(&mut psbt, SignOptions { allow_all_sighashes: true, ..Default::default() })?;
+```
+
