The new release includes the following changes:
- Updates the lattice parameters tables to support the ring dimension of 216 and 217 for ternary and Gaussian secrets (#806)
- Adds application specifications validator for BGV, BFV, and CKKS (#710)
- Updates the parameter sets for CGGI/DM/LMKCDEY; adds low-probability-of-failure parameter sets (below 2−120) (#673)
- Adds several optimizations for BFV, including support for modulus switching during computation (#682, #715, #731)
- Fixes parameter estimation bugs for BGV, BFV, and CKKS (insecure configurations were possible for scenarios with hybrid key switching) (#785, #786)
- Includes several fixes related to handling the map of automorphism keys for various EvalSum*KeyGen operations (#756, #773, #783, #797)
- Adds support for selective serialization/deserialization of automorphism/rotation keys (#775)
- Updates the HRA-Secure BGV PRE implementation based on HRA-Secure Homomorphic Lattice-Based Proxy Re-Encryption with Tight Security (#767)
- Includes many other bug fixes
