Release 0.74.1

Release 0.74.1 - 24-12-13

Note: Please also see the 0.74.0 release notes at https://github.com/Blockstream/gdk/releases/tag/release_0.74.0 if you are upgrading from a pre-0.74.0 release.

Added

• Added an example Dockerfile for building AWS lambda compatible gdk deployments.

Changed

• Singlesig: Allow some incorrect descriptors/xpubs returned by Ledger HWW.
• GA_create_transaction: Return the currently calculated transaction fee in the "fee" element when an insufficient fee error occurs.

Fixed

• Singlesig: Prevent the relay fee from falling below the network minimum.
• Liquid: Update the allowed maximum of transaction inputs to 256, not 255.

Release 0.74.0

Release 0.74.0 - 24-11-25

Added

Changed

• GA_psbt_sign: Now signs all required inputs and then attempts to finalize. If the PSBT is not fully signed, some inputs will remain unfinalized.
• GA_psbt_sign: Now adds any missing wallet inputs scripts when signing.
• OpenSSL: build with PSK support for better static linking compatibility.
• Python: Remove vestigial Python 2 support.
• Dependencies: Update libwally.
• Misc code cleanups and documentation fixes.

Fixed

• PSBT: When a user signature is present for an input, use it instead of asking the signer to re-sign.
• PSBT: Fix user-only signing of multisig inputs, by adding the user signature and leaving the input unfinalized for future Green signing.
• PSBT: Fix detection of expired multisig CSV inputs when finalizing v0 PSBTs.
• Python: Fix session cleanup to happen when a Session falls out of scope or is garbage collected. Previously sessions would generally be cleaned up only on program exit, which could lead to excessive resource use.

Release 0.73.4

Release 0.73.4 - 24-11-12

Note: Please also see the 0.73.3, 0.73.2, 0.73.1 and 0.73.0 release notes at https://github.com/Blockstream/gdk/releases/tag/release_0.73.3, https://github.com/Blockstream/gdk/releases/tag/release_0.73.2, https://github.com/Blockstream/gdk/releases/tag/release_0.73.1 and https://github.com/Blockstream/gdk/releases/tag/release_0.73.0 if you are upgrading from a pre-0.73.0 release.

Added

• Singlesig(Liquid): Add support for discounted Liquid fees. Discounted fees can now be used on the Liquid testnet networks.
• Crypto: Add GA_rsa_verify to verify an RSA challenge.
• Android: Release binaries now support devices with 16k page sizes.

Changed

• Transactions(Liquid): Use appropriate coin selection criteria when discounted Liquid fees are in use.
• GA_create_transaction: Return the error "Fee change below the dust threshold" when the change output left over from paying fees is below the dust threshold. Previously this case returned "Insufficient funds for fees" (which is still returned if there is not enough value in fee UTXOs to pay the transaction fee).
• SPV: Update built-in checkpoints.
• Liquid: Update built-in assets and icons.
• Dependencies: Update tor, rust-tempfile, libwally.

Fixed

• Transactions: Further fixes for Liquid weight calculations.
• Singlesig(MacOS): Fix occasional localhost proxy resolution issues.

Release 0.73.3

Release 0.73.3 - 24-10-25

Note: Please also see the 0.73.2, 0.73.1 and 0.73.0 release notes at https://github.com/Blockstream/gdk/releases/tag/release_0.73.2, https://github.com/Blockstream/gdk/releases/tag/release_0.73.1 and https://github.com/Blockstream/gdk/releases/tag/release_0.73.0 if you are upgrading from a pre-0.73.0 release.

Added

• GA_create_redeposit_transaction: Add support for "expired_at" to create re-deposit transactions for UTXOs that will expire in the future.
• GA_get_balance/GA_get_unspent_outputs/GA_create_redeposit_transaction: Add support for "expires_in" to support filtering for UTXOs that expire in the given number of blocks from the current block height.

Changed

• Transactions: Improve error messages when too many or duplicate inputs are used.

Fixed

• Transactions: Fix weight calculation for Liquid when all inputs to a transaction are non-segwit (i.e. p2sh, p2pkh). This fix prevents the actual fee rate from becoming lower than the desired fee rate.
• Singlesig (Liquid): Prevent returned fee rates from falling below the networks real relay fee rate of 0.1 sat/vbyte.

Added

• GA_create_redeposit_transaction: Added a new call to create transactions that re-deposit wallet funds. For Liquid this call handles multiple-asset re-deposits and adds L-BTC fee inputs as required to cover re-deposit fees.

Changed

Release 0.73.0 - 24-09-18

Added

• PSBT: Allow PSBT creation from singlesig descriptor watch-only sessions.

• GA_broadcast_transaction: Added support for broadcasting a PSBT/PSET directly. The PSBT is automatically finalized; callers no longer need to manually finalize and extract before sending a signed PSBT.

Changed

• GA_broadcast_transaction: This call has changed to run via an auth handler, in order to allow extending its functionality.
