12- division by 0 in Fl_ellcard_Shanks [2.6.1, #1474]
13- ellwp([1,I]) -> stack overflow [2.6.0]
14- sumdedekind(h < 0, k < 0) wrong result; if gcd(h,k) > 0 as well
15- galoisexport(G, 1) -> SEGV
16- ??default(log) no longer worked
17- rnfalgtobasis, rnfbasistoalg, rnfeltup, rnfeltdown, rnfeltabstorel,
rnfeltreltoabs were not treating their inputs consistently, and
accepted (or crashed on) too many incorrect inputs.
18- rnfideal* did not handle correctly the 0 ideal
19- rnfidealtwoelt(non integral ideal) => crash
20- nfeltreducemodpr(K, non invertible elt mod pr,...) => wrong result
(now an e_INV error)
21- rnfbasis: wrong result due to a mistake in gen_if_principal
[2.6.0, revert d62f0de01]
22- nfsolvemodpr(nf,a,b,P): a must be invertible, as in matsolve
(was not documented, used to SEGV). Raise an error if not.
23- various bnrdisclist crashes
24- bnrclassno(bnf, prime ideal) -> SEGV
25- forpart(x=k,) raised an exception if k < 0 [ now empty loop ]
26- deriv(constant) now returns 0 in the base ring (not gen_0).
27- inconsistencies and mistakes in deriv / intformal of t_POLMOD: forbid
integration wrt the main variable of x.mod, deriv(Mod(x, x^2),x) was
Mod(1,x^2) and deriv(Mod(y,x^2),y) was 0 instead of respectively 0 and
Mod(1,x^2)
28- idealchinese with t_POLMOD inputs -> input error
29- idealchinese with denominators -> SEGV
30- qflll(Mat(0)) returned Mat(1)

33- relative error in eint1 was larger than expected
34- select(t_LIST,,1) [ indirect select ] didn't work
35- vecsort(List(),,4) -> SEGV
36- factorpadic / polrootspadic lost accuracy when converting output from
integers to t_PADICs (factorpadic(t^2 + 3^5, 3, 5) -> irreducible factor
(1 + O(3^5))*t^2 + O(3^5)*t + O(3^0)
37- Mod(0,0) is no longer valid => division by 0 (as Mod(x,0) for x != 0)
38- RgX_to_RgV no longer accepts other types than t_POL. Use Rg_to_RgV for
a more permissive function
39- broken Fq_sqrt when T != NULL and t_INT input
40- ispower(1009^11) -> 0 [2.6.0]
41- ellinit([0,1,1,0,1],2).group -> SEGV

46- randomprime(2) -> SEGV [#1493, 2.6.0]
47- forqfvec(v,[;],0,) -> SEGV [#1495]
48- poliscyclo(x^0) -> 2
49- truncation (precision) errors in bnfnarrow [#1491]
50- matadjoint assumed that n! is invertible. If this is not the case, now
use a safe algorithm
51- leading coefficient of elldivpol ignored the characteristic,e.g.
E=ellinit([a1,a2,a3,a4,a6*Mod(1,2)]); elldivpol(E,2)
52- gcd involving a t_FFELT -> SEGV
53- oo loop in ispower for huge arguments / oo loop in prime iterator
in congruence classes [#1498, 2.6.0]
54- L=[1,2,3]; apply(x->L=x,L) -> SEGV ( idem select and [|x<-] operators )
55- (k+1.)/k - (2*k+1.)/k -> incorrect object
56- gcd(x,0.) -> 1 but gcd(x,Pol(0.)) -> x [ the former is correct, since 0.
is inexact and may represent an arbitrary small non-zero real number ]
57- eint1 misbehaved at large precision [#1499]
58- polredbest(T,1) incorrect if T non-monic or degree 1
59- nfcertify might miss a factor to be certified, e.g.
P=polcompositum(x^4+437*x+19,x^5-571*x+27)[1];
nfcertify(nfinit(P, [2,3,5])) was empty
60- polresultantext(t_POL in y, t_POL in y,y) -> U/V as t_POL in x [#1509]
61- inconsistent handling of t_POL "divided by" scalar among the variants
of Euclidean division (%, divrem, \, ...). E.g. x % 2 is OK, but
x % Mod(2,3) was not. We now follow the semantic of
grem/gdeuc/poldivrem: a scalar is understood as a t_POL of degree 0
in the proper variable [#1510]
62- incorrect rounding in mulur
BA 63- Configure: --includedir was ignored
64- add GC in RgV_dotproduct / RgV_dotsquare
65- ZX equal was checking variables, contrary to the spirit of the
specification (and contrary to RgX_equal). Specify behaviour properly:
none of the internal .*[xX]_equal function check variable numbers.
66- arithmetic functions did not accept factorizations of negative integers
(whereas most of them are defined for negetive integers)
BA 67- Configure --time=ftime actually tested times, not ftime. Remove ftime
from the default list of timer functions (reports wallclock time, not
CPU time) [#1523]
68- polredabs() could (find then) forget some polynomials [#1511]
69- poldisc(x^3 + Mod(2,3)*x^2) --> e_INV
70- (Mod(4.,y^2+1)*(1 + O(x)))^(1/2) -> junk (= [2.0+O(x)),2.0+O(x)]~).
Worse if other t_POLMOD coefficients. Now exception.
71- sin(O(p)) returned 1+O(p) instead of O(p)
Changed
1- default help text for a user function is now as in \u:
fun =
(args)->body
2- after addhelp(f,...), ?f no longer include default help text for a
user function (function code). Type 'f' to see the function code.
3- primes([a,b]) now returns the primes in the interval [a,b]
4- install: add symbol name in library and GP prototype to default help
5- the rnf structure format
6- library functions: rename rnfelementxxx -> rnfeltxxx,
rnfidealhermite -> rnfidealhnf
7- allow mathnf(t_VEC) [ apply Mat() automatically ], gives acces to the
ZV_gcdext() routine.
8- mathnf(,2) (generic vs integral t_MAT) is deprecated: we always test
the matrix entries and choose the appropriate routine
9- bnrclassno: allow all standard ways to define class fiels (A,B,C),
not only bnf + module
10- bnrinit(bnf,f): allow using idealstar(bnf,f) in place of f
11- Let Set(t_VECSMALL v) behave as Set(Vec(v))
12- ffgen(T) now checks whether T is squarefree (testing for
irreducibility is too expensive)
13- variable() no longer raises exceptions: if no variable can be
associated to the object, return 0. Thus "if (!variable(x), )" may be
used to test wether x has a "variable".
JD 14- polcyclo(n, x) now works for all roots of 1
15- quadpoly no longer accepts vector/matrix arguments, see 2.6.0,C94
16- [libpari] renamed ZM_hnfremdiv -> ZM_hnfdivrem
17- x t_REAL * y t_INT: either convert y to t_REAL (as before) or use
integer multiplication (if lg(x) >> lg(y))
18- GP: all results are now stored in GP history, together with the time
to obtain them [ we used to only store non-gnil results, and no timings ]
19- chinese(t_POL,t_POL): allow polynomials of different degrees
20- deplin(): use FpM/Flm/F2m routines if possible (like all other generic
linear algebra routines)
21- FpM_gauss(a,b,) from modular kernel no longer allow all types of input:
split into FpM_FpC_gauss (b t_COL) and FpM_gauss (b t_MAT). Same for
all modular xxx_gauss functions
22- O(1/x^2) --> error [ now equivalent to O(x^-2) ]
23- faster evaluated polhermite/pollegendre
24- polhensellift / ZpX_liftfact: use quasi-linear ZXX_mul_Kronecker instead
of RgX_mul (~ Karatsuba)
25- [libpari] renamed gcmpX -> gequalX
26- [libpari] renamed ordred -> polredord
27- the prid structure returned by idealprimedec: the anti-uniformizer
tau (pr_get_tau) is now stored via its multiplication table
28- rnfpolredabs(x,3) did not conform to the documentation (which did not
make sense). Fix documentation and function, for rnfpolredbest as well.
29- [libpari] renamed recip -> serreverse
30- lift(x,'v) / centerlift(x,'v) now only lift t_POLMODs in variable v,
no longer (most) t_INTMOD / t_PADICs met along the way
31- lift / centerlift no longer raise an exception when they encounter
a non-arithmetic type (e.g. a t_REAL or even a t_STR) in a structure.
They just copy the offending sub-object as-is.
32- generic polynomial Euclidean division (grem, gmod, poldivrem): when
result is the zero polynomial, use RgX_get_0, not gen_0 / pol_0
33- rnf.pol (absolute defining polynomial / Q) is now called rnf.polabs,
rnf.pol is now the relative polynomial, defining the relative extension
over the base.
BA 34- FpXYQQ_pow: change order of moduli to be consstent with FpXQXQ_pow.
BA 35- FlxYqQ_pow: renamed to FlxYqq_pow, and moduli order changed.
36- idealstar(K,id), allow to input 'id' as a factorization into prime
ideals, as produced by idealfactor
37- define eulerphi(0) = 2 [ now eulerphi(n) = znstar(n).no for all n ]
38- allow subst(t_SER,x,exact 0): subst(2+O(x),x,Mod(0,3))->Mod(2,3) [#1513]
39- [libpari] rename gsh -> gsinh, gch -> gcosh, gth -> gtanh,
gash -> gasinh, gach -> gacosh, gath -> gatanh, ggamd -> ggammah
(follow GP names)
40- no longer naively use the Karatsuba/3M formula to multiply t_COMPLEX
of t_REALs: loss of accuracy is too important and unpredictable from the
user's point of view [ e.g. (1+ 1e-90*I)*(1e90+I) -> 1. E90 + 0.E52*I,
when the definition directly yields 1. E90 + 2*I ]. Could use it when
the exponents of real/imaginary parts are close, increasing the
precision by the exponent difference (increasing overhead...): not done
yet.

1- genus2red: an implementation of Liu's algorithm to determine the
reduction of a genus 2 curve (at p > 2). Based on genus2reduction-0.3,
http://www.math.u-bordeaux1.fr/~liu/G2R/ (Cohen & Liu, 1994)
mostly rewritten from scratch:
- adapted to pari-2.*
- somewhat modularized
- fixes all known instances of 'bug27' and 'bug28' (at p = 3, reported
through Sage users).
- bench 'genus2red' contains a check of at least one instance of each
of Namikawa-Ueno's types + all cases on which the original
genus2reduction was known to fail. [CAVEAT: the interface will change]
2- allow to startup gp with flags --default key=val (or -D key=val):

13- PARI functions FpM_hess, FpM_charpoly, charpoly, RgM_Rg_sub,

ellsearch(t_STR) as per the ellconvertname correspondance

18- [libpari] ZX_rescale_lt

24- allow lists of elements in chinese()
Changed
1- gp --primelimit lim (gp -p lim) is deprecated. Use the generic form
'gp -D primelimit=lim' (setting primelimit is now mostly useless, anyway)
2- gp --stacksize lim is deprecated. Use gp -s lim or the generic form
'gp -D parisize=lim'
3- partitions() interface to match forpart()
4- improve qfbred(t_QFI) for "small" inputs
5- bnfnewprec: ensure we recompute bnf from scratch at most once (could
happen many times in makematal())
6- [make bench] properly align results if 'printf' is available
7- [libpari] the *_invimage function no longer accept a t_COL second
argument: use the RgM_RgC_invimage variant. They now return NULL when

8- [libpari] replace the forvec_start() function by a standard
iterator: forvec_init() / forvec_next()

12- Mulders/Hanrot-Zimmerman short products for power series
HC 13- new mpveceint1 implementation: faster and more precise
14- version string for development versions: added number of reachable

Removed
1- drop support for "gp -b buffersize" (obsolete since 2.2.10, 04/2005)
2- drop backward compatibility 'gp -emacs', 'gp -test'. Use the '--emacs'
and '--test' forms.
Done for version 2.6.0 (released 15/05/2013):

Changed
1- mathnf: swapped flag 3 and 5.

3- ellinit(... singular curve ...]): return [] instead of raising an error
4- GP set elements are no longer converted to t_STR (requiring "eval" to
recover the underlying object). Arbitrary GENs can be stored in a set.
5- moved Odos/* to relevant src/systems subdirectory
6- removed Odos directory
7- no longer allow Vec()/Vecrev(), Col(), Vecsmall(), without argument.
Use [], []~, Vecsmall([]), respectively.

15- if znlog() has no solution, return [] instead of error

underlying (Z/N)^* is cyclic
17- renamed gen_eltorder -> gen_order
18- logfile: strip properly color escape sequences [#1225]
19- change nfbasis(T, flag, fa) to nfbasis(T, listP). flag was used to invoke
round2 instead of round4 (inefficient=> useless) OR to only
partially factor poldisc(T), up to primelimit (very dangerous since
primelimit is a global variable). Now listP describes a list of primes,
and we return a basis of an order which is p-maximal at all those primes:
either a vector of primes, a factorisation (as fa before) or an integer
B to indicated {p <= B} (a safe and flexible version of nfbasis(T, 1)).
nfdisc() was changed similarly.
20- first call isanypower() in BPSP_psp_nosmalldiv() when input is > 2^512
[ < 1% of required time, 1 order of magnitude faster when it succeeds ]
[ #1074 ]

to denote "not an n-th power residue in sqrtn"
BA 27- global_err_data is now a GEN.
BA 28- more usable form of alarm(s, code): evaluate code, aborting after s
seconds. Return the result or a t_ERROR object.
29- [non-Unix systems] the name of the preferences file is now "gprc.txt"
(it remains ".gprc" on Unix systems)
30- also look for the preferences file in PARI's "datadir"
31- removed rootsold() code : polroots(x, 1) is no longer accepted
32- rewrite ellan using C-longs + new function anellsmall()
33- renamed all libpari error codes [ pari_err() arguments ]
34- allow t_VECSMALL in vecextract
35- look for a few more short vectors in polred(), only return subfields
and the best primitive polynomial [wrt discriminant]
36- [library] remove precdl argument in ellwp0: use a t_SER argument like
in all other transcendental functions.
37- ellsigma / ellzeta: allow t_SER arguments, like ellwp.
38- polcoeff(x+2*y,1,y) -> 2 [ was 2*x^0 ]
39- quadhilbert / quadray: replace final polredabs call by polredbest [#1025]
40- listsort() now uses the cmp() comparison function, and becomes fully
compatible with setsearch() [#1167]
41- vecsort(,,2) [lexicographic order] is now always on. The flag is
now deprecated and ignored.
42- allow t_SER with integral coefficients to use asymptotically fast
(ZX_mul / ZX_sqr) polynomial multiplication
LGr43- let initprimes0 use an existing prime table
44- rename stackmalloc -> stack_malloc. Add stack_calloc
45- matimagecompl() now returns a permutation (t_VECMALL) no longer a t_VEC
46- remove config/gitversion from 'make snapshot' tarball

BA 48- agm now returns the optimal AGM
49- unify make_emacs_tags / make_vi_tags => make_tags + fix problems for
(exuberant-ctags)-based etags. Both tag files (emacs / vi) contain
the same tags now.
50- ellglobalred(E) now also returns the conductor factorization [4th compo]
51- library functions *_incremental_CRT no longer need the product of the
moduli, instead they compute it and update the running modulus.
52- factor_proven now affects all the factoring machinery, as documented, i.e
also multiplicative function (moebius, sumdiv,...)
53- allow t_VECSMALL in lex()
54- nfrootsof1(K) check whether K.pol is a translate of a cyclotomic pol.
[initial patch LGr, #1175]
55- format of cached Bernoulli table: now a t_VEC of t_FRAC / t_REALs.
Removed bern() macro. The new data must be accessed using bernfrac /
bernreal.
56- [libpari] simplify init_primepointer(n, p, &pd) interface
=> init_primepointer(n, &pd). Remove argument 'p', ignore the previous
value of pd [ remove assumption that it pointed into a prime table ]
and always set pd to a pointer into the private prime table.
57- forprime loop: no longer allow to modify the loop index
? forprime(p = 2, 10, p = [])
*** at top-level: forprime(p=2,10,p=[])
*** ^---
*** prime index read-only: was changed to [].
58- faster forparii() [ for() with t_INT lower bound ]
59- forprime(p = a, b, ...) now iterates over arbitrary ranges of primes,
independently of 'primelimit'. Parameter 'b' can be omitted (no upper
limit). More generally primelimit is no longer a true limit to iterate
over primes: all libpari functions use the forprime_t interface
60- rename ggval -> gvaluation
BA 70- GP function ellpow is renamed to ellmul
BA 71- rename powell->ellmul, addell->elladd, subell->ellsub
72- is_pth_power interface [ pass a forprime_t iterator ]
73- polrootsmod(, 4) is no longer accepted
74- revert to Ramanujan's formula to compute Pi [ + binary splitting ]
75- polinterpolate(,, 'x) use divide & conquer algorithm
BA 76- binary(0) now return []
77- polisirreducible() now avoids factoring in most cases
HC 78- reimplement incgam()
79- allow eint1(t_COMPLEX)
80- when 'echo = 1', no longer echo commands if they were entered
interactively [commands ended up printed twice]
81- unless 'echo = 1', no longer log commands entered non-interactively
when 'log = 1'. '\r file' used to log the entire content of 'file'.
82- allow thue(t_POL, rhs) for thue(thueinit(t_POL, rhs))
83- elltors now uses division polynomials by default
84- modified "Hit Return to Continue" message so that it becomes a comment
when copy-pasted
85- rnf_fix_pol() takes an extra argument, the calling function's name
86- fast gerepilecopy() for leaves
87- rename leftright_pow_fold -> gen_pow_fold, leftright_pow_fold_i
-> gen_pow_fold_i
88- upowuu now returns 0 on overflow
89- primes(n) no longer needs precomputed primes
90- prime(n) no longer needs precomputed primes
91- primepi(n) no longer needs precomputed primes
92- removed 3s delay when recompiling PARI after modifying a header
[ Was there to avoid problems on slightly out-of-synch NFS fileserver
host. Had become an annoyance on fast multicore servers, esp. when
bisecting to find a broken commit. ]
93- improve Configure --tune + let tune -t/-tt/-ttt print more and more
verbose messages [ old 'tune -t' corresponds to current 'tune -tt' ]
94- arithmetic functions no longer accept vector / matrix arguments [ to
later allow passing factorization matrices ]: use apply()
BA 95- rename RgX_check_ZXY -> RgX_check_ZXX, ZXY_max_lg -> to ZXX_max_lg
96- elleta() and elleisnum(e, 2) to use a theta series formula in
O~(prec^(3/2)) instead of O~(prec^2).
BA 97- zv_cmp0 renamed to zv_equal0
98- allow ellinit / Qp for arbitrary reduction type
99- ellpointtoz(E / Qp, ...), now return phi(P) [ used to return the same
result for phi(P) and phi(-P) [ split multiplicative reduction ],
resp. phi(P) + 1/phi(P) [ non-split reduction ]
100- ellinit(E / Qp).tate : the u component is now always a square root
of u2, also in the non-split case (in which case it lives in a
quadratic extension of Qp)
101- renamed library function divsum() => sumdivexpr()
102- listpop(empty list) => no-op [ was "domain error" ]
103- ellap, ellak, ellan: allow non-minimal model
104- when timer = 1, no longer print timing if the time is negligible;
in particular, no timing should be printed when defining a user function
or and alias.
105- The proper way to initialize an nf structure when the polynomial
discriminant is hard to factor is nfinit([T, listP]), where listP
specifies a list of primes (see ??nfinit). nfdisc, nfbasis, all the
polred functions allow analogous arguments (see Changed-19). This is
cleaner and more flexible than old flags relying on the value
primelimit (e.g. nfinit([T, nfbasis(T, 1)]), now deprecated). Also,
the nfinit function now sees the local specifications and can
take steps to avoid problems (instead of taking for granted a basis,
without knowing whether it is correct or not). The result can
also be certified (nfcertify)
106- polredabs() with (deprecated) nf_PARTIALFACT flag (or new [T,listP]
argument) now returns 0 if the resulting order cannot be proven to be
maximal.
107- rename bezout() -> gcdext(), polresultant() -> polresultantext()
108- the prime table is now computed once and for all on startup and can
no longer be increased by modifying primelimit: the dynamic forprime
machinery allows fast primes up to primelimit^2 which is more than
enough even with a small table. The default value of 500.000 is already
larger than necessary
109- removed the mechanism allowing prime gaps larger than 255 in the
prime table: as a result it now limited to 436273290, allowing fast
primes up to 1.9 10^17
BA110- permtonum/numtoperm now use the standard lexicographic numbering
111- issquare(t_INTMOD), ispower(t_INTMOD): factor modulus incrementally,
in case we hit a local non-residue -> early abort [#1376]
112- gphelp + OS/X : make "open" the default PDF viewer (was "acroread")
113- renamed exp_Ir -> expIr
