## [Unreleased]
8+
## [0.6.0] - 2024-11-04
9+
10+
#### Added
11+
- New module `musig` implements the MuSig2 multisignature scheme according to the [BIP 327 specification](https://github.com/bitcoin/bips/blob/master/bip-0327.mediawiki). See:
12+
- Header file `include/secp256k1_musig.h` which defines the new API.
13+
- Document `doc/musig.md` for further notes on API usage.
14+
- Usage example `examples/musig.c`.
15+
- New CMake variable `SECP256K1_APPEND_LDFLAGS` for appending linker flags to the build command.
16+
17+
#### Changed
18+
- API functions now use a significantly more robust method to clear secrets from the stack before returning. However, secret clearing remains a best-effort security measure and cannot guarantee complete removal.
19+
- Any type `secp256k1_foo` can now be forward-declared using `typedef struct secp256k1_foo secp256k1_foo;` (or also `struct secp256k1_foo;` in C++).
20+
- Organized CMake build artifacts into dedicated directories (`bin/` for executables, `lib/` for libraries) to improve build output structure and Windows shared library compatibility.
21+
22+
#### Removed
23+
- Removed the `secp256k1_scratch_space` struct and its associated functions `secp256k1_scratch_space_create` and `secp256k1_scratch_space_destroy` because the scratch space was unused in the API.
24+
25+
#### ABI Compatibility
26+
The symbols `secp256k1_scratch_space_create` and `secp256k1_scratch_space_destroy` were removed.
27+
Otherwise, the library maintains backward compatibility with versions 0.3.x through 0.5.x.
