6- factor(x/y) -> error
7- factor(y/x) -> x^-1 [ instead of y^1 * x^-1 ]

Changed
1- polcoeff is deprecated and renamed polcoef: it now only applies
to scalars, polynomials, series and rational functions; no longer to
vector/matrices or quadratic forms (use [] or "component").
2- [libpari] rename polcoeff0 -> polcoef, polcoeff_i -> polcoef_i,
truecoeff -> truecoef
3- add optional argument to denominator/content/numerator to allow
better control over semantic. E.g.
No arg: denominator([1/2, 1/x, 1/y]) -> 2*y*x
denominator([1/2, 1/x, x/y]) -> 2*x
denominator([x/2, 1/x, 1/y]) -> y*x
With arg: denominator(,1) is 2 in all 3 cases
denominator(,x) is x in all 3 cases
denominator(,y) is y in all 3 cases
4- factor(t_RFRAC): sort factors by increasing degree
5- [libpari] rename constant LOG2 -> M_LN2 (from math.h if available)
6- ellweilcurve: allow input in ellisomat form
7- [libpari] rnf_get_nfzk / nf_nfzk / nfeltup interface (czknf was
useless, return and use nfzk)
8- the rnf struct from rnfinit has changed, the new format is not
compatible with pari-2.9
9- improved eta(x^k)
10- sinc(t_SER) more accurate
11- in prettymatrix format, no longer print all 0 x n matrices as [;]:
use [;] iff n = 0 and matrix(0,n) otherwise
12- bnrdisclist returned t_MATs whose columns were t_VECSMALL
13- mateigen(m): fall back to qfjacobi when m close to symmetric [#2059]

bnfisprincipal(K,P); \\ oo loop

subst(x+O(x^2),x,0*x) -> 1 + O(x) [ instead of 0 ]

70- factor(x^2 * (1+O(5^2))) -> domain error
71- for T in Q_p[X], factor (round then compute multiplicity)
and issquarefree (assume input is separable) did not agree. Now,
factor() repeats irreducible factors according to apparent
multiplicity (note that the multiplicity is not well defined for
inexact inputs, which are close to being inseparable, i.e.
v_p( disc(T) ) is large compared to the input accuracy). On the
other hand, factorpadic with exact input is able to compute
multiplicities reliably.

PB 79- nfinit(t_POL of deg 1, 3) => incorrect change of variable
80- subst(t_SER, x, x+O(x^N)) was slow [ e.g. ellj(x+O(x^10000)) ]
BA 81- setrand(2);polclass(-5032,27) -> wrong result
82- polredabs(non-monic t_POL, 1) => potentially wrong transformation map
83- if 'a < 'b < 'c, charpoly(Mod(a, a^2 + Mod(b,b^2+1)), c) => 1
[ now error: the result can't be repreѕented as a t_POL in 'c, only
as a t_POLMOD modulo b^2 whose coefficients are t_POL in 'c ]
84- mathouseholder: missing sanity checks (SEGV, didn't accept t_COL)
85- bestapprPade did not handle positive valuation correctly [#1945]
PB 86- subst(Mod(1/z, y), z, x) -> wrong answer [#1949]

102- mathnf([x;1]) -> SEGV [#1971]
BA 103- ispower((x^3+ffgen([2^127-1,3])*x+1)^2,2,&r);r was wrong [#1976]

BA 120- matsupplement(Mod(matrix(5,1),2)) --> SEGV [#1996]

+19278898978723566612544;bnfinit(p).cyc}
=> [60,2,2,2,2,2,2,2,2,2] instead of [6,2]
134- nffactor(y^8-y^6+y^4-y^2+1,x^4-1) -> concatenation error [#2009]
135- vecsort / vecsearch: comparison function was required to assume
integral values; allow t_INT, t_FRAC or t_REAL
136- mathess was very unstable, and so was charpoly(,,2) [#2010]

Changed
1- rewrite bnfnarrow
2- the bid struct from idealstar has been changed, the new format is
not compatible with pari-2.9
3- bnrdisclist output is now an ordinary vector (not a vector of vectors)
4- made nfsign() / nfsign_arch() reliable [ use algebraic method
besides floating point approximation to real embeddings ]
5- support ??refcard-ell (or mf/nf/lfun)
6- [libpari internals] bnrinit(,,1) [with generators] is no longer
necessary for bnrsurjection()
7- bnrinit(,,1) is no longer necessary for bnrL1, bnrconductor,
bnrrootnumber, bnrstark, rnfkummer, galoissubcyclo
8- msfromell: use a (much faster) modular algorithm, allow a vector
of isogenous curves
9- mseval(W,s,p): allow 2x2 matrix for the path 'p' argument
10- allow mseval(W, t_MAT, p) to evaluate many symbols simultaneously
11- allow polrootsreal() and polsturm() with non-rational real polynomials
(input is rounded first)
BA 12- FlxX_shift did not support negative (left) shift.
BA 13- [libpari] rename FpX_fromdigits -> FpXV_FpX_fromdigits,
FpXQX_fromdigits -> FpXQXV_FpXQX_fromdigits
14- made lngamma(t_COMPLEX) faster
15- made sumnummonieninit(,1) faster
HC 16- sumnummonieninit(a) for [a,a] did not conform to documentation.
Change to sumnummonieninit(b) for [1,b]
17- improve prime() and primepi() by adding more checkpoints [#1878]
18- lfun(Dirichlet character): switch automatically to lfunchiquad
(Kronecker) if char has order <= 2
19- nfchecksigns: replace by rigorous algorithm
20- asympnum: better tunings => usually finds more terms
21- extended help: make ?? op work for ALL operators (=> GP operators@2)
22- idealstar(,N) : always include generators, for all values of flag
[ this is cheap, allowing not to compute it doesn't make much sense;
and G.gen is now always defined. ]
23- let ellsea call the generic algorithm when q <= 523 to avoid an oo-loop
24- sqrtnr algorithm (Newton iteration instead of exp(log(x)/n)
BA 25- quadgen/quadunit: allow to specify the variable name instead of w.
26- [libpari] rename vecbinome -> vecbinomial
27- [libpari] rename padic_lindep -> lindep_padic, Xadic_lindep ->
lindep_Xadic
28- x^(t_FRAC) use sqrtnr if possible
BA 29- keri replaced by ZM_ker (use modular algorithm)
30- lfuncreate() change of format for (p,d)->Lp closure:
- Lp here and in bad primes [p,Lp] must now use the actual local
factor and not its inverse
- d is now the exact number of terms needed (was 1 less), i.e.
one need only return Lp + O(x^d)
- bad primes are given as a separate 2nd component:
[Lp, [[p1,L1],...[pk,Lk]]], not as [Lp, [p1,L1],...[pk,Lk]]
31- faster nfgaloismatrix / nfgaloisapply(nf,s, ideal)
32- nf struct: nf[7] now stores nf.zk / content(nf.zk). Old format is
still supported (to read in data involving old-style nf generated by
gp version < 2.10) but incurs a small speed penalty.
JD 33- move plotport.c to libpari
34- default window size for hi-res plots using --graphic=X
35- component(t_POL T, n) used to return polcoeff(T, n-1) for all n >= 1
[ undocumented compatibility behaviour, deprecated since the
introduction of polcoeff ], and raised an exception for n <= 0.
Now returns a true GEN component whenever it exists and raises an
exception when it does not [ n <= 0 or n > polcoeff(T)+1 ].
BA 36- Fl_addmul_pre: change arguments order to follow Fp_addmul convention
37- issquarefree / isfundamental with integer argument: allow factored form
38- change polred-type algorithm to return 'x' (no longer 'x-1') for
the field of rational numbers (make it consistent with polredabs)
BA 39- ellisomat(E,{fl}) is now ellisomat(E,{p},{fl}) (p degree of isogenies)
40- the definition used in polred / polredbest / polredabs to decide
what is the "best" polynomial to return
41- removed resultant_all, use RgX_resultant_all
42- polresultant: no longer compute the content of arguments
(potentially very expensive for a generically small gain)
43- support Q(i) in Q_denom / Q_remove_denom
BA 44-[libpari] rename {FpXQXQ,FlxqXQ,F2xqXQ}V_aut{sum,trace,pow} to
{FpXQXQ,FlxqXQ,F2xqXQ}_aut{sum,trace,pow}
BA 45-[libpari] FpXQXQ_auttrace now identical to FpXQ_auttrace
BA 46-[libpari] RgX_type now only handles polynomials.
47-log: change threshold between Taylor / AGM when x close to a power
of 2 [#1934]
48-[libpari] ZM_inv and QM_inv interface
49- K.tu[2]: make it a t_INT if possible, else a t_POLMOD
50- removed warning "Mod(a,b)^n with n >> b : wasteful"
51- ellpadicmatrix now returns a pair of matrices (instead of a matrix
whose entries are pairs of values)
52- ellpadicheight and ellpadicmatrix no longer accept [p,[a,b]]
arguments; use * [a,b]~
53- ellpadics2: allow curves with multiplicative reduction
54- E/Qp now allowed in ellcard, ellap, ellgroup, ellissupersingular,
ellpadicfrobenius, ellpadics2, ellintegralmodel, elllocalred
55- E/Qp convert coefficient to exact form using centered residues
56- msissymbol now returns a GEN (gen_0/gen_1) instead of a long, allow
t_MAT arguments and return a vector of 0/1 in this case.
57- allow mseval(M, t_MAT)
58- change 'debugmem' default value to 1;
no memory-related message at value 0 (not recommended under gp).
BA 59- V=galoisfixedfield(,,2): return V[1] in the same variable as the
coeffs of V[3] instead of P.
60- numtoperm now returns a t_VECSMALL (so that results can be
multiplied as permutations, etc.), no longer a ZV
61- improve Fp_sqrt for p = 5 (mod 8) [Atkin's formula]
62- improved matrixqz(,‐1 or -2) by using matkermod
63- The functions psdraw, psploth and psplothraw and the default psfile
are obsolete. Use one of plotexport, plothexport or plothrawexport
with format "ps" and write the result to file.
AP 64- new implementation of matsolvemod; old matsolvemod0 is deprecated
65- plotcolor(w,c) now returns the [R,G,B] value attached to c
66- allow plotdraw(w) for plotdraw([w,0,0])
67- allow isprime(n) to use ECPP
68- isprime(n,1) no longer outputs a certificate, use primecert(n)
69- isprime(n,1) no longer uses APRCL for large prime divisors of n-1
(pure Pocklington-Lehmer-Selfridge); use primecert(n).
70- getrand() encoded results in a way that depended on 32bit/64bit arch
71- thue(p, rhs) is much easier when p has no real roots; don't insist
on computing bnfinit(p) in this case [#2003]
72- use Newton in expm1
73- change rnfpolredabs so that it outputs a canonical polynomial. As a
result, the function is no longer Obsolete.
74- allow polrecip(scalar x) -> x
75- extend factormod(f, D) for general finite fields: D = p prime
[over Fp], D = [T,p] (over Fp[x]/(T)), or omited [over field of
definition of f]. Same for polrootsmod.
76- factorff and polrootsff are now obsolete. Use factormod/polrootsmod
77- Ser(s, 'x, d) now always return a series with d significant terms.
It used to return a t_SER s in 'x verbatim and to use all given
coefficients for a t_VEC/t_COL. Only if d is explicitly given,
no change for Ser(s,'x)
78- elllocalred, ellap, ellcard, ellissupersingular, ellgroup(,0):
allow models which are not p-integral
79- ellgroup: allow E over number field
80- factorback([;]) is now invalid [ [;] is not the empty factorization,
factor(1) = matrix(0,2) is ]
81- cmpiu / cmpiu, equaliu / equalui : no longer assume that t_INT argument
is non-negative
82- rename diviu_rem -> absdiviu_rem, udiviu_rem -> uabsdiviu_rem,
udivui_rem -> uabsdivui_rem
83- allow E.omega, E.eta, E.area for E over number field
84- ellpointtoz for E over number field
AP 85- algnorm, algtrace and algcharpoly now have an optional flag to get the
absolute version over an alginit algebra
AP 86- renamed algsplittingmatrix -> algtomatrix
AP 87- algleftmultable now always returns the multiplication table on the
integral basis
AP 88- merge algdecomposition + algsimpledec -> algsimpledec
AP 89- algpoleval: new syntax for matrix argument algpoleval(al,pol,[x,mx])
BA 90- ellmoddegree: return only the modular degree, do not depend on current
precision.
91- polsturm: allow non-squarefree polynomials (count distinct roots)
AP 92- merge algdim + algdim -> algdim(,{abs=0})
AP 93- merge algleftmultable + algtomatrix -> algtomatrix(,{abs=0})
Removed
1- file 'MACHINES' (no longer maintained)
2- useless argument nf in ZC_nfval, ZC_nfvalrem, pr_equal, ZC_prdvd
3- useless flag argument in polrootsmod
4- [libpari] useless function Flx_roots_naive; rootmod and rootmod2
are now an alias for polrootsmod (both have been deprecated for years)
rootmod0 is just as obsolete.
