11/15/2019: PALISADE v1.7.a is released

* Adds an optimized implementation of the CKKS scheme for approximate (real-number) homomorphic encryption. The implementation features automated rescaling/modswitching and hybrid key switching.
* Adds an optimized implementation of the FHEW scheme for Boolean-circuit homomorphic encryption, supporting standard HE parameters. Performs bootstrapping for each binary gate, and hence supports the evaluation of arbitrary Boolean circuits.
* Adds the ring dimension as an option when generating crypto contexts for BFV variants.
* Improves the noise growth of the BEHZ variant of BFV (referred to as the BFVrnsB scheme in PALISADE).
* Fixes several bugs.

* Serialization/deserialization is now much faster (by 3x to 10x). Both binary and JSON formats are supported.
* By default, PALISADE compiles w/o external dependencies in Linux and Windows, i.e., NTL/GMP is now optional for these OSes.

* Fixes the vulnerability found in https://eprint.iacr.org/2017/785 (PKC'19) for the PRE schemes based on BGV/BFV 
* Adds PRE modes for BGV/BFV that are secure under honest re-reencryption attacks (recommended security for practical use)
* Adds support for splitting lattice trapdoor sampling into offline and online phases (used by digital signatures, IBE, and ABE constructions)
* Fixes bugs related to the multi-threaded mode of operation

02/11/2018: PALISADE v1.4.1 is released

Fixes a bug affecting the IBE and CP-ABE implementations (some unit tests for IBE/CP-ABE were entering in an infinite loop in about 10% of the runs).

6/15/2018: PALISADE v1.2 is released

PALISADE v1.2 provides several important advancements and improvements to the library.  Most notably, we provide:

* The Bajard-Eynard-Hasan-Zucca RNS variant of the BFV scheme is added to the library
* The implementation of the Halevi-Polyakov-Shoup RNS variant of the BFV scheme is significantly improved
* Large multiplicative depths (up to 100 and higher) for both RNS variants are now supported.
* Several low-level optimizations, e.g., in Number Theoretic Transform and NTL multiprecision math backend, are implemented.
* Multiple improvements in plaintext encodings.
* Software engineering improvements: extended batteries of unit tests, cleaner design of the matrix class, better CryptoContext wrapper, etc.
* Fixes for bugs which have been brought to our attention.
