- Update to pqcrypto-kyber 0.7.9
- Rust: Allow mixed comparisons (PartialEq) between ServiceId and
Aci/Pni. This is convenient but is also a breaking change: call
sites that compared `service_id == aci.into()` will now be
ambiguous; the fix is to remove the `.into()`.
- Rust: Expose ServiceId::kind as pub
- Restore compatibility with Rust 1.72 (and possibly earlier if you
only use certain crates), and clarifies that updating this minimum
version counts as a "breaking change" (i.e. v0.39.0 rather than
v0.38.x).
- Belatedly note that git is a compilation dependency (via boring-sys)
- Start of libsignal-message-backup crate, which validates the backup
files generated by the apps. Not ready for general use.
- Continued work on SVR3
