Release 0.76.0

Release 0.76.0

Added

• Liquid(Singlesig): Add support for BIP-86 P2TR (Taproot) wallets.
• Liquid(AMP): Ensure watch-only AMP accounts do not run out of addresses.
• HWW: Add a new device JSON key "supports_liquid_p2tr" to indicate P2TR
  inputs can be signed by the device.

Changed

• Testnets: The PIN server for testnets has been changed to a testing instance.
  You will need to recreate PIN logins for test wallets with a PIN login enabled.

  Users that do not trust esplora to behave honesty should run their own electrum server
  rather than relying on SPV.

Release 0.75.2

Release 0.75.2 - 25-05-08

Note: Please also see the 0.75.1 and 0.75.0 release notes at https://github.com/Blockstream/gdk/releases/tag/release_0.75.1 and https://github.com/Blockstream/gdk/releases/tag/release_0.75.0 if you are upgrading from a pre-0.75.0 release.

Fixed

• GA_login_user: Fix singlesig descriptor watch-only re-login on an existing session.
• Liquid(testnet): Fix the Liquid testnet explorer URL in network parameters.

Changed

• Build: Update rust to 1.81.0, which is now the MSRV for building gdk.
• Python: Remove support for Python 3.8.
• Python: Update the Python wheel license classifiers for newer build tools.
• Dependencies: Update rust dependencies.

Release 0.75.1

Release 0.75.1 - 25-04-01

Note: Please also see the 0.75.0 release notes at https://github.com/Blockstream/gdk/releases/tag/release_0.75.0 if you are upgrading from a pre-0.75.0 release.

Fixed

• GA_create_transaction: Return an invalid amount error instead of an assertion failure if any output amount in a transaction is 0.

Release 0.75.0

Release 0.75.0 - 25-03-20

Note: As of this release, discounted fees are enabled by default for Liquid on all networks. No action is required by users or developers to enable this feature. Transactions will now pay about 1/10th of the fees before this update.

Added

• Bitcoin(Singlesig): Add support for BIP-86 P2TR (Taproot) wallets.
• HWW: Add a new device JSON key "supports_p2tr" to indicate P2TR inputs can be signed by the device.
• Liquid: Automatically enable fee discounting for Liquid environments.
• Add an AWS lambda docker build image and a Python wheel for Python 3.10 lambda containers.

Changed

• Multisig: The minimum supported gdk version is now 0.68.0. However, we strongly recommend all clients update to the latest released gdk version to ensure they have all available security updates, bug fixes and new features.
• Liquid: Allow callers to create dust (non-change) transaction outputs.
• Liquid: Lower the L-BTC dust threshold to 21 l-satoshi following ELIP 201.
• Build: Update rust to 1.71.1, which is now the MSRV for building gdk.
• Singlesig(Bitcoin): Outgoing wallet mempool transactions with invalid signatures (as might be expected from a malicious Electrum server) are no longer silently filtered. Attempting to bump an invalid transaction will raise an error as it does in multisig. Otherwise, any underlying valid transaction will confirm at some point and the invalid transaction will disappear.
• Signing: Allow signing of transactions with mixed segwit and pre-segwit inputs in all cases except for transactions involving AMP assets on Liquid.
• GA_get_unspent_outputs_for_private_key: Do not include wallet keys such as "subaccount" and "pointer" in the returned UTXOs (these were added mistakenly in release 0.68.0).
• Dependencies: Update rust dependencies, libwally, json, boost, autobahn-cpp, websocketpp.
• JSON: Improve error messages for developers when JSON values are passed as incorrect types (e.g. an array is expected but another type is given).
• Build: Various code quality and build-related cleanups.

Fixed

• PSBT: Ensure updating PSBT values overwrites existing values in all cases.
• PSBT: Do not attempt to add keypaths and other metadata for non-wallet inputs.
• Transactions: Fixed some edge cases in signing and verifying transactions containing non-wallet inputs.
• Watch-only(Singlesig): Prevent watch-only login with an empty descriptor array.
• GA_sign_message: Ensure an "error" element is always returned (empty if the call succeeded).
• Singlesig: Fix a deadlock that could cause singlesig sessions to hang.
• Python: Fix Python wrapper compilation with later Python SDK versions.
• JSON: Fix miscompilation of jSON handling code with older gcc versions.
