## BDK

The next BDK 1.0 alpha release `1.0.0-alpha.1` is nearly ready. The marquee change for this milestone is the introduction of the `ChainOracle` type and related refactoring. The new `ChainOracle` makes it possible for BDK 1.0 based wallets to directly access key blockchain data from sources such as a Compact Block Filter client (BIP-157/158) or via the Bitcoin Core RPC interface (coming in future releases). Other notable 1.0 alpha changes are improved `no_std` support for our WASM using friends, and fixing Rust 1.48 version support to keep the corporate hats happy. For good measure a couple new features were also added to get `sat_per_kwu` for `FeeRate` and a new descriptor template to make it easier to create P2TR (BIP-086) wallets.

Notable BDK sub-project releases: `rust-esplora-client` with version `0.6.0` and `rust-electrum` version `0.16.0` both supporting the latest and greatest `rust-bitcoin` version `0.30.0`.

In other news the team has started doing discord [#review-club-meeting](https://discord.gg/5EKbGVXBN8) chats starting with a two part series by [Evan Linjin](https://twitter.com/evanlinjin/) for linked-list data structure internal improvements to his above mentioned `ChainOracle` work. Keep an eye on Discord for announcements for future sessions.

## BDK Language Bindings

[Thunderbiscuit's BDK-FFI Update]

A new release of the BDK language bindings is out (0.29.0). In this release we added support for Windows on Kotlin/JVM as well as some new Python targets, and by user request, exposed the `Wallet.is_mine()` and `Script.to_bytes()` methods. The bdk-flutter and bdk-rn projects also releases new versions this past quarter.

We are starting to build examples and documentation on our approach to building bindings for BDK; check out the [blog post](https://bitcoindevkit.org/blog/bindings-scope/). We're happy to say we're seeing a lot of new faces on the Discord server and builders using the bindings!
