Hello,
Today we'd like to announce the release of version 0.3.1 of libsecp256k1:
https://github.com/bitcoin-core/secp256k1/releases/tag/v0.3.1
This is a bugfix release after 0.3.0 (which was not announced on this list)=
. For the full release notes of 0.3.0 and 0.3.1 see:
https://github.com/bitcoin-core/secp256k1/blob/master/CHANGELOG.md
but the impetus for this release is the discovery that Clang 14 and later b=
ecame smart enough to optimize out a specific timing side-channel protectio=
n mechanism in the code that could leave applications vulnerable to a side-=
channel attack. This has been fixed in 0.3.1.
We strongly recommend any users of the library to upgrade if their code may=
end up being compiled with Clang 14+. Bitcoin Core release binaries are no=
t affected.
