CHANGELOG

[0.3.1] - 2025-10-24

poulpy-hal

• Add bivariate convolution (X, Y) / (X^{N} + 1) with Y = 2^-K

poulpy-core

• Fix typo in impl of GGLWEToRef for GLWEAutomorphismKey that required the data to be mutable.

[0.3.0] - 2025-10-23

• Fixed builds on MACOS

Breaking changes

• The changes to poulpy-core required to break some of the existing API. For example the API prepare_alloc has been removed and the trait Prepare<...> has been broken down for each different ciphertext type (e.g. GLWEPrepare). To achieve the same functionality, the user must allocated the prepared ciphertext, and then call prepare on it.

poulpy-hal

• Added cross-base2k normalization

poulpy-core

• Added functionality-based traits, which removes the need to import the low-levels traits of poulpy-hal and makes backend agnostic code much cleaner. For example instead of having to import each individual traits required for the encryption of a GLWE, only the trait GLWEEncryptSk is needed.

poulpy-schemes

• Added basic framework for binary decicion circuit (BDD) arithmetic along with some operations.

[0.2.0] - 2025-09-15

Breaking changes

• Updated the trait FillUniform to take log_bound.

poulpy-hal

• Added pure Rust reference code for vec_znx and fft64 backend.
• Added cross-backend generic test suite along with macros.
• Added benchmark generic test suite.

poulpy-backend

• Added FFTRef backend, which provides an implementation relying on the reference code of poulpy-hal.
• Added FFTAvx backend, which provides a pure Rust AVX/FMA accelerated implementation of FFTRef backend.
• Added cross-backend tests between FFTRef and FFTAvx.
• Added cross-backend tests between FFTRef and FFT64Spqlios.

poulpy-core

• Removed unsafe blocks.
• Added tests suite for FFTRef and FFTAvx backends.

Other

• Fixed a few minor bugs.

[0.1.0] - 2025-08-25

• Initial release.
