Please test pari-2.9.2 prerelease 1

Dear PARI developers,

We have made available a prerelease of PARI 2.9.2 (stable).

This is a large update, so please test throughly.
The expected release date is set to the 05/04/2017.

(Note that https is now available)

Please test the prerelease tarball:

The digital signature is 

Please test the 64bit windows installer:

This release should fix problem on windows 64 when using very large

I have also built the 32bit Windows installer:

and the following standalone Windows binaries:



and the following MacOS DMG:


and the following MacOS stand-alone binary:
