[Bill Allombert <Bill.Allombert@math.u-bordeaux.fr>]

Dear PARI developers,

We have made available a prerelease of PARI 2.9.5 (stable).

This is a large update, so please test thoroughly.
The expected release date is set to the 18/05/2018.
This release in particular fixes issues on mips systems. 

Please test the prerelease tarball:
<https://pari.math.u-bordeaux.fr/pub/pari/snapshots/pari-2.9.5-pre1.tar.gz>

The digital signature is

Please test the 64bit windows installer:
<https://pari.math.u-bordeaux.fr/pub/pari/windows/snapshots/Pari64-2-9-5-pre1.exe>

This release should fix problems with the plotting engine on Windows.

I have also built the 32bit Windows installer:
