CHANGELOG: - Update of `PrecisionStats` in `ckks/precision.go`: - precision/error stats computed as log2 of min/max/average/... - fields renamed (`MinPrecision` -> `MINLog2Prec`, `MaxPrecision` -> `MAXLog2Prec`, ...) - `rlwe.Scale` has a `.Log2()` method - Update of `mod1.Parameters` fields (made public, some removed) - Improvement of the relinearization key-generation protocol (reduce the degree of the shares) - Serialisation of bootstrapping keys - Lower noise incurred by `ModUp` - Evaluation keys can be compressed (public element `a` can be generated from a seed) - More doc formatting - Fix various bugs: - `ShallowCopy` of the CKKS bootstrapping evaluator and BFV evaluator not deep enough. - PSI example failing - Incorrect reset of pointer in uniform sampler - Error when doing inverse NTT with small degree - Mod1Evaluator changes the input ciphertext Co-authored-by: Andrea Caforio <andrea.caforio@protonmail.com> Co-authored-by: Jean-Philippe Bossuat <jean-philippe@tuneinsight.com>
