Ann: SWI-Prolog 8.1.26

Releases
1

Dear SWI-Prolog user,

SWI-Prolog 8.1.26 is ready for download. This quick release is due to a
flaw in the 8.1.25 version that caused xpce, required for the
development tools, not to be installed on Non-Windows systems. This
version also fixes possible build failures if the user has conflicting
packs (add-ons) installed and a couple of issues on 32-bit platforms.

Enjoy --- Jan
