Most “progress” since CL has been very “one step forwards, two steps back”. The interactive development, amazing debugging (don’t unwind the stack), powerful macros, nearly-C-speed (if optimized), great tooling, etc. are mostly kept by other Lisps, but at the same time most every new language in the Lisp family loses some aspect of what makes CL great. http://stevelosh.com/blog/2018/08/a-road-to-common-lisp/ http://stevelosh.com/blog/2018/08/a-road-to-common-lisp/ is highly recommended, as well.
