Unsession: "Clojure 1.12 Overview"
summary
Clojure 1.12 adds concrete work: fast chunked drop/partition for indexed and algorithmic collections via a new internal “ey drop” interface and new partitionv/splitv functions that keep the original collection type; a formalized namespace-intern vars policy that prevents previously mysterious var disappearance; interactive dependency loading with adlib/adlibs/sync-deps that shells out to the Clojure CLI and tools.deps to add jars to the REPL classpath; virtual-thread fixes replace synchronized with locks to avoid parking issues; method-value adapters and functional-interface support let Java methods and Clojure functions interop without manual wrappers.
