Today I have released (with much help from Fare) ASDF 3.1.3. We urge implementations that are currently shipping with 3.1.2 to move forward to 3.1.3. 3.1.3 has no API incompatibilities that we know of, and contains significant bug fixes. Most significantly, 3.1.3 fixes bugs that impede hot-upgrade from 3.1.2 to a later version of ASDF, which is critical to ASDF development. In addition, we have fixed multiple bugs in ASDF system search caching, that impeded correct use of restarts involving adding new systems to a running CL. Regards, Robert Goldman
