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 moveforward 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 fixesbugs that impede hot-upgrade from 3.1.2 to a later version of ASDF,which is critical to ASDF development. In addition, we have fixedmultiple bugs in ASDF system search caching, that impeded correct use ofrestarts involving adding new systems to a running CL.
