* Thu Oct 27 2022 Andrea Manzini - Update to release 2.15.0
* The GP language:
* Notion of DebugLevel \"domains\" that allow to finely control diagnostics.
* The syntax setdebug(dom, val) and default(def, val) are now recognized in the GPRC file.
* Linear Algebra:
* qflll() now implements most LLL modes in fplll (fast, dpe and heuristic), allowing large speedups. Directly and in the many functions that use the LLL algorithm.
* New GP function snfrank(), a utility function returning q-ranks from Smith Normal Forms
* Elementary Number Theory:
* New GP function: harmonic(), to compute generalized harmonic numbers
* Reworked Euler numbers, analogously to Benoulli\'s: eulervec() is now faster and caches computed values, and a new GP function eulerreal() computes floating point approximations.
* Elliptic Curves: New module to compute the Mordell-Weil group of rational elliptic curves
* See https://pari.math.u-bordeaux.fr/pub/pari/unix/pari-2.15.0.changelog for details.
