Added
- Python: Add Python 3.12 wheels to the binary releases/PyPI.
- tx: expose `wally_tx_input_clone`/`wally_tx_input_clone_alloc` for input cloning.
- Build: Add new static analysis CI runs.
Changed
- Javascript: The npm build now uses nodejs 20, as nodejs 16 is end-of-life.
- Android: Update android NDK to version 26b.
- libsecp256k1-zkp: The library has been updated to include the latest
changes to its cmake infrastructure.
- cmake: Now takes advantage of the new libsecp256k1-zkp cmake files to build
experimental modules and export the project in cmake style. cmake now also
builds test and collects coverage data.
Fixed
- Build: Don't use `which` on Debian as it is now deprecated.
- Various bug fixes from static analysis.
- Various build and documentation fixes.
release_1.1.0
Added
- PSBT: Allow extracting partially finalized transactions in `wally_psbt_extract` by passing a new `WALLY_PSBT_EXTRACT_OPT_FINAL` flag.
- tx: Allow getting the number of items in a transactions input witness via `wally_tx_input_get_witness_num_items` / `wally_tx_get_input_witness_num_items`.
Fixed
- tx: `tx_input_get_witness` now correctly returns 0 bytes written if passed a `NULL` input.
release_1.0.0
This release contains ABI changes; it is not ABI compatible with prior versions.
Added
- The library version number is now available as compile time constants (`WALLY_MAJOR_VER`, `WALLY_MINOR_VER`, `WALLY_PATCH_VER`, `WALLY_BUILD_VER`), and at runtime via `wally_get_build_version`.
- Added support for wallet policies (https://github.com/bitcoin/bips/pull/1389).
- Added support for iterating and querying keys in descriptor/policy expressions, including support for key origin information such as fingerprint and path.
- The library allocation functions (which may be overridden by the caller at runtime) are now exposed as wally_[malloc|calloc|free|strdup|strdump_n]. Libraries using wally that wish to respect the callers allocation strategy can use these to avoid having to expose their own customizable allocator.
- Added support for encrypted request/response protocols using ephemeral keys via `wally_aes_cbc_with_ecdh_key`.
- The PyPI wheel uploads now include an `sdist` source distribution, allowing install on otherwise-unsupported architectures.
Changed
- The library now follows semantic versioning as per https://semver.org/.
- Elements support is now enabled by default, reflecting the common library usage. Please see the `configure --help` entries for `--disable-elements` and `--disable-elements-abi` for details.
- The ABI of the library is now consistent by default regardless of whether it is built with or without Elements support.
- The constant EC_SIGNATURE_DER_MAX_LOW_R_LEN has been changed from 71 to 70, to reflect that wally always produced low-R, low-S signatures when grinding.
- When configured to build as a static library, linking to libwallycore.a requires additionally linking to libsecp256k1.a.
- Wally can now be configured to build against a system-wide libsecp256k1 by passing `--with-system-secp256k1` to configure.
- The Python wheel can now be built with standard Python tooling such as `build`, and can be built from an uploaded source distribution.
- The Python wheel can now be built with dynamic linking to libwallycore and libsecp256k1-zkp/libsecp256k1.
- libsecp256k1-zkp has been updated to the latest master version as at the time of release.
- Some functions in the c++ header wally.hpp have changed interface slightly. Note that this header is deprecated and will be replaced in an upcoming release with higher level wrappers in the same manner as Python and JS.
- The docker-based builds have been streamlined and simplified. NPM builds in particular are now much faster.
Fixed
- Fixed a bug affecting signing PSBT taproot inputs.
- Fixed extern libsecp256k1-zkp linkage for windows static builds.
- Several build fixes/improvements and CI updates have been made.
