Hello sage-devel,

As far as we know, there are no more remaining issues for the PARI
update (#9343).  We haven't had any doctest failures for a while now.
The main issues recently have been with PARI not compiling properly on
various machines, but all those seem to be fixed now.

I have made a complete Sage distribution sage-4.6.prealpha4, based on
sage-4.5.3.rc0 with the new PARI and some more updates.  You can
download it from
http://sage.math.washington.edu/home/jdemeyer/dist/sage-4.6.prealpha4.tar

In order to test this thoroughly, extract the tarball and then:
  cd sage-4.6.prealpha4
  make
  env SAGE_CHECK=yes SAGE_TUNE_pari=yes ./sage -f
pari-2.4.3.svn-12577.p5.spkg
  make ptestlong

On sage.math.washington.edu, this worked without problems (apart from a
sometimes-reproducible error in devel/sage/sage/tests/startup.py)


The following tickets have been merged in sage-4.6.prealpha4 (w.r.t.
sage-4.5.3.rc0):
#9343: PARI upgrade
#9860: Port changes in PARI 2.3.5.p4 (#9722) to current 2.4.3
#9591: Upgrade genus2reduction due to Pari upgrade to svn snapshot 12577
- a pre-release of Pari 2.4.3
#9592: Upgrade lcalc to work with Pari svn snapshot 12577 - a
pre-release of Pari 2.4.3
#9845: lcalc doesn't build on cygwin due to missing time.h include
#9750: Document that PARI no longer assumes more than GRH.
#9636: Catch output from PARI in Sage.
#9400: Modify the NumberField constructor to pass in optional integer B
such that all the internal PARI routines will replace the discriminant
by its gcd with B, making some things massively faster.
