as previously announced, I have released the first Quickref version compatible with Declt 4.0 (which is now at beta 2) and which is going to keep track of the development over there. Because Declt 4 is currently considered in beta state, so is Quickref 4 for the time being.
There are a number of important changes in this new major version of the library. Not much interesting from the outside is an infrastructure overhaul which improves the parallel support. The index generation code has also been rewritten to benefit from the recent changes in Declt. Slightly more interesting from the outside is an improvement of the self-documenting aspects of the public interface when used interactively, along with more usage correctness checks. Also, the build environment has been upgraded to Debian Bullseye.
But the most critical change, of course, is the name for the 4.x series. In compliance with the general theme (Iron Maiden songs), and because Quickref 4 is meant to closely follow the brave new Declt version, I thought "Brave New World" would be nice. On the other hand, as Declt wanders through its uncharted 4.0 beta territory, Quickref 4 is likely to suffer the consequences, so perhaps "The Aftermath" is more appropriate...
Anyway, the Docker images are up to date, and so is the Quickref website, currently documenting 2110 Common Lisp libraries.
