I downloaded, compiled, and installed SBCL 1.2.11, the latest monthly release of the SBCL system. When I ran the regression tests (on OS X 10.10.3) I got one failure. The main development platform is Linux so I’m assuming this is an OS X anomaly—I don’t see anything on the Web about the failure. I’m not going to worry about it until next month’s release.
This month’s release has four enhancements and two bug fixes. As usual, we all owe to SBCL developers our thanks for the excellent job they do in making monthly releases of this fine tool.
