- attest: Add a new enclave, with support for v4 of the DCAP PCS API
Android + Server
- Support for Android KitKat has been dropped
- Testing on Windows should now work
iOS
Use as a CocoaPod now depends on prebuilt Rust binaries that can be fetched from build-artifacts.signal.org. This requires adding
ENV['LIBSIGNAL_FFI_PREBUILD_CHECKSUM'] = '...'
to the consuming Podfile. The referenced archives are downloaded to ~/Library/Caches/org.signal.libsignal, and are unarchived as part of the build.
- ScannableFingerprint.compare now correctly takes an opaque collection of bytes to compare against rather than another fingerprint object (which could only be created on the current device)
- APIs for AES-256-CTR and AES-256-GCM have been added
- The API for AES-256-GCM-SIV is now more idiomatic
Desktop
- Building for 32-bit ARM Linux should work again
