* Mon Oct 26 2020 Jan Engelhardt <jengelh@inai.de>
- Update to release 2.13.0
* New libpari functions: perm_sqr, perm_powu, perm_orderu, quodif.
* Added asymptotically fast quadunit.
* Faster intnumgaussinit and change default number of points
to B/4, suitable when b - a ~ distance to the nearest pole.
* In libpari, perm_pow now takes a t_INT exponent, permorder
and perm_order return a t_INT.
* sizebyte(objects containing t_LIST): would assign size 3 to all lists
* permorder returned incorrect results for large orders
* cure SIGSEGV on [Map(Mat([0, 0])), [0, 0, 1]]
* cure SIGSEGV on zeta(I+2^(-64))
* cure infinite loop on p=[4,54];lfunmf(mfinit(p,0), mftraceform(p,0))
* printf("%5.2f",M) transposed M
* bnfinit instability at low accuracy. E.g., at \p38
P=x^7+22*x^6+184*x^5+764*x^4+2020*x^3+3792*x^2+5712*x+4;
bnfinit(P,1).no -> 4 times too large
* Accuracy problems in bnfisunit after bnfinit(P,1). E.g.,
P=x^7-22*x^6+169*x^5-568*x^4+1263*x^3-1506*x^2+2295*x+2;
setrand(1); K=bnfinit(P,1); U=bnfunits(K,idealprimedec(K,2));
bnfisunit(K,4*(x^2-18*x+85)/x^2*Mod(1,K.pol),U) -> error
