Bump secp256k1-sys version to 0.8.1
We are ready to release a new minor version of `secp256k1-sys`, in order
to do so we must make change the symbol names to reflect the new version
as well as the usual changelog and version bump.

In preparation for releasing `secp256k1-sys` v0.8.1 do:

- Rename symbols to from `0_8_0` -> `0_8_1`, done mechanically (search
  and replace)
- Add changes log notes (includes changelog entry for 0.8.0)
- Bump `secp256k1-sys` crate version 0.8.0 -> 0.8.1, justified because
  we have added a new public function.

secp256k1-sys

This crate provides Rust definitions for the FFI structures and methods.

Vendoring

The default build process is to build using the vendored libsecp256k1 sources in the depend folder. These sources are prefixed with a special rust-secp256k1-sys-specific prefix rustsecp256k1_v1_2_3_.

This prefix ensures that no symbol collision can happen:

  • when a Rust project has two different versions of rust-secp256k1 in its depepdency tree, or
  • when rust-secp256k1 is used for building a static library in a context where existing libsecp256k1 symbols are already linked.

To update the vendored sources, use the vendor-libsecp.sh script:

$ ./vendor-libsecp.sh depend <version-code> <rev>
  • Where <version-code> is the secp256k1-sys version number underscored: 0_1_2.
  • Where <rev> is the git revision of libsecp256k1 to checkout.

Linking to external symbols

If you want to compile this library without using the bundled symbols (which may be required for integration into other build systems), you can do so by adding --cfg=rust_secp_no_symbol_renaming' to your RUSTFLAGS variable.
