I made an incompatible change in 1.721: before that, it was a *convention* that configuration files in configuration directories :include'd by the source-registry or the output-translations configuration should have :type "conf". This interacted poorly with backup files stored in same directory by default by various editors. There was also the confusing issue that "*.*" would match anything on some implementations (e.g. SBCL) but only files with a . in their name in others (e.g. CLISP). So I made the convention something enforced and this should change the problem, at the cost of backwards incompatibility with whoever started using that feature while defying the convention.
Otherwise, I've made a few changes based on feedback from various people, whom I thank.
I also strongly disrecommend releases 1.714 to 1.718 that have a bug in an incomplete cleanup that prevent them from loading some systems that use symbols to name components, such as fiveam and many more. My apologies for the change. The same cleanup seems to have broken ASDF-INSTALL (one line change needed, oops), and anyone who previously defined methods on the internal function find-component (in retrospect, I should have changed the name of the function.)
