| Changes in fplll-5.0: | |
| - switched to C++11 | |
| - switched to more open development model on GitHub, cf. CONTRIBUTING.md | |
| - support for computing optimal pruning parameters for a given lattice | |
| dimension/shape/radius | |
| - BKZ 2.0: recursive BKZ preprocessing, extreme pruning, gaussian | |
| heuristic bound | |
| - precomputed BKZ (2.0) reduction strategies up to block size 90, cf. | |
| https://github.com/fplll/strategizer | |
| - Self-Dual BKZ and Slide reduction | |
| - faster, recursive enumeration implementation | |
| - Gaussian lattice sieving | |
| - Python interface at https://github.com/fplll/fpylll | |
| - optional dumping Gram-Schmidt vectors during execution of algorithm | |
| - q-ary lattice generator | |
| - instructions on how to cite | |
| - optional support for doubledouble and quaddouble | |
| - pkg-config support | |
| - API documentation at https://fplll.github.io/fplll/ | |
| - revised build system supporting parallel build | |
| - copyright headers | |
| - dropped fplllv3 compatibility layer | |
| - greatly increased test coverage, tests are run on every commit or | |
| pull request | |
| - coding/naming convention | |
| - FP API improved to allow for more readable/natural code | |
| Changes in fplll-4.0.4: | |
| - compatibility for packages that still expect to build against | |
| libfplll version 3. | |
| - updates of config.sub and config.guess | |
| - better check that MPFR and GMP are installed | |
| - compilation issue with NaN's | |
| Changes in fplll-4.0.3: | |
| - Compiler issues with Cygwin | |
| Changes in fplll-4.0.2: | |
| - Changed formulation for the license, in README.html | |
| Main changes in fplll-4.0.1: | |
| - Compiler warnings about unused parameters fixed | |
| Main changes in fplll-4.0.0: | |
| - BKZ reduction, available with 'fplll -a bkz -b block_size' | |
| ******************************************************************* | |
| Changes in fplll-3.1.3: | |
| - Fixed build process when DESTDIR is defined | |
| Changes in fplll-3.1.2: | |
| - Memory leak fixed in the wrapper. | |
| Main changes in fplll-3.1.1: | |
| - Some code is no longer included in the header files but is compiled in | |
| libfplll instead. The -lfplll option will now be required for apps which could | |
| be compiled without it. | |
| - 'make install' puts all header files but fplll.h in a subdirectory named fplll | |
| - New programming interface for the library (documented in README.html). | |
| - 'generate' renamed to 'latticegen'. | |
| - Removal of fplll_verbose. Use the '-v' option instead. | |
| - Minor bugs fixed in all versions of LLL. | |
| - More important bugs fixed in the SVP solver. | |
| - Optimization of the SVP solver. | |
| - By default, 'fplll -a svp' now gives the coordinates of a shortest vector in | |
| the _standard_ basis. | |
| ******************************************************************* | |
| The main differences between fplll-2.1 and fplll-3.0 are the following: | |
| - short lattice vector enumeration algorithm (by Xavier Pujol). | |
| - GPL -> LGPLv2 | |
| - no more need to specify the number of rows and columns in the input | |
| of the fplll binary. | |
| - new version of dpe.h [Patrick Pelissier and Paul Zimmermann] | |
| ******************************************************************* | |
| The main differences between fplll-2.1 and fplll-2.0 are the following: | |
| - "configure/make/make install" packaging (thanks to Martin Albrecht) | |
| - few minor changes to make fplll portable to SAGE (thanks to Martin | |
| Albrecht) | |
| - conversion scripts between MAGMA and fplll formats. | |
| - a bug fixed in fast_early (discovered by Martin Albrecht) | |
| ******************************************************************* | |
| fplll-2.0 is an improved version of fplll-1.3. Parts of it resemble | |
| Magma's LLL (Allan Steel, Damien Stehle) and/or NTL's LLL (Victor | |
| Shoup). | |
| The improvements from fplll-1.3 to fplll-2.0 were mostly performed | |
| by David Cade. Here is a brief summary of the changes: | |
| - the major algorithmic improvement is the so-called wrapper, which | |
| chooses for the user a guess of the right sequence of heuristic/proved | |
| variants to use, in order to finish as quick as possible, but in a | |
| reliable way. | |
| - the early-reduction strategy of Allan Steel has been integrated. It | |
| consists in size-reducing vectors earlier than what would have been | |
| done in the standard LLL. This is not integrated into the wrapper yet. | |
| - we switched from C to C++, to simplify our lives with the wrapper. | |
| It is extremely convenient for the use of the underlying arrithmetics | |
| (integers and floating-point numbers). | |
| - we translated the matrix indices by 1: the first matrix entry is | |
| B[0][0] instead of B[1][1]. | |
| - automatised triangular option: the code looks at the matrix and | |
| decides how close to upper-triangular it is. |
