- update to 2.15.4:
  * lfunan(lfunetaquo([12,1;13*12,1]),1) -> stack overflow
  * FpM_intersect could return a Flm
  * 3- ifac_isprime could be called on input with tiny
    divisors
  * nfcompositum could return non-monic polynomials
  * gammamellininvinit(vector(9,i,1)) -> SEGV
  * incorrect sanity check in rnfeltdown ("not in base
    field")
  * precision loss in gammamellininv
  * [pthread] parselect could crash
  * rare infinite loop in ellsaturation
  * quadunitindex(8461,2)->1 instead of 3
  * chinese(Mod(1,3)*(x^2+x+2),Mod(1,5)*(x-1))->incorrect
    leading term
  * lindep([0,x]) -> SEGV
  * [libpari] RgX_div_by_X_x: wrong variable number
  * MS 14- hyperellratpoints(2*x^3+x^2-x,1000) -> wrong result
  * ellisogeny over a nf -> inconsistent variables error
  * w=3;quadgen(5) -> print x instead of w
  * FpX_convol: wrong result for mixed degree
  * 18- mateigen(,1): eigenvalues were given as t_VEC or
    t_COL. Use t_COL.
  * ellcard over small finite field: potential oo-loop
- add pari.keyring for source integrity validation

- update to 2.15.2:
  Fixed
    polredbest: rare error "inconsistent concatenation"
    hypergeom([0,0],[1],2)
    powers(t_INT, ...) was very slow
    factor(prod(i=1,20,nextprime(2^i)), 131) would include 131
    sumeulerrat(x^2/(1+x),2) -> FPE
    lambertw(10^1000) -> overflow
