Hi, GNAT 3.15p has been released last November and it is still not packaged in Debian. Since, the GNAT from GCC tree is still not stable enough, I'd suggest that we keep on updating the ACT public release.
Jon Ward told he was packaging it but nothing seemed to happen. Is anyone still working on this or should I give it a try (I'm not the best skilled though)? Cheers, -- Jérôme Marant http://marant.org
