+
+A new release of BDK is out: [`v0.6.0`] brings some new API calls, renamed types and some bugfixes.
+
+You can find the full [v0.6.0 changelog][changelog] on GitHub.
+
+## What's new in v0.6.0
+
+Below are some highlights of the new release:
+
+### A new way to generate addresses
+
+The old `get_new_address()` method has been upgraded into a more generic `get_address()`, which takes a [`AddressIndex`] argument. `AddressIndex` is defined as an enum with the following variants:
+- `AddressIndex::New` increments the derivation index stored in the database and returns a new address. It's equivalent to the old `get_new_address()`.
+- `AddressIndex::LastUnused` returns the address for the current derivation index if no usage has been detected. `sync()` should be called to ensure the internal database is up to date.
+- `AddressIndex::Peek(index)` returns the address at a given derivation index, without updating the database.
+- `AddressIndex::Reset(index)` returns the address at a given derivation index, and stores that value in the database.
+
+```rust
+// Prints the first ten addresses without updating the derivation index
+for index in 0..10 {
+    println!("Address #{}: {}", index, wallet.get_address(AddressIndex::Peek(index)?));
+}
+```
+
+### Easier multiparty transaction creation
+
+A new method called [`get_psbt_input()`] has been added to the `Wallet` structure, and it makes it very easy to get a complete PSBT input with all the required metadata for a given UTXO. This can be very convenient
+when working with `add_foreign_utxo()`, which was added in the previous release:
+
+```rust
+// On Alice's wallet
+let alice_utxo = LocalUtxo { ... };
+let alice_psbt_input = wallet_alice.get_psbt_input(alice_utxo.clone())?;
+send_input_to_bob(alice_utxo.outpoint, alice_psbt_input)?;
+
+// On Bob's wallet
+let mut builder = wallet_bob.build_tx();
+builder
+    .add_recipient(addr.script_pubkey(), 60_000)
+    .add_foreign_utxo(alice_outpoint, alice_psbt_input, satisfaction_weight)?
+    ....
+```
+
+### Renamed types
+
+To keep our coding style in line with the best practices defined by the Rust language, we've renamed some of our types and enum variants to avoid using [upper case acronyms](https://rust-lang.github.io/rust-clippy/master/index.html#upper_case_acronyms).
+
+Some examples are:
+- `UTXO` -> `Utxo`
+- `RBFValue` -> `RbfValue`
+- `BIP69Lexicographic` -> `Bip69Lexicographic`
+- `P2PKH` -> `P2Pkh`
+- `BIP44Public` -> `Bip44Public`
+
+### New MSRV
+
+Due to some changes in one of our dependency, our MSRV has been bumped up from `1.45` to `1.46`, which was released in August 2020. The last release fully supporting `1.45` is `v0.5.1`.
+
