2017.05.30
Today we released PGI 17.5 [1], a quality-improvement release that also expands operating system support to include Ubuntu 17.04 and Redhat Enterprise Linux 6.9.

DOWNLOAD ACCESS
Only users with a PGI account linked to a PGI for-fee license can download 17.5 [2] without assistance from PGI. Licensed end-users in large organizations who are _ not_ linked to a PGI for-fee license should _ first contact their license administrator_ or IT department for
assistance. PGI Sales [3] can also assist with granting download access to such users.

EVALUATIONS
For purchase evaluations, we first encourage prospective users to try PGI Community Edition [4], which is currently 17.4. If prospective customers wish to try 17.5, they should contact PGI Sales for a temporary evaluation [5] download link.

Thank you for your continued support of PGI Compilers & Tools!
