Clojurians Log v2

PluMCP: Clojure/ClojureScript library for building https://modelcontextprotocol.io/ Clients and Servers Version 0.2.0-rc1 is released to Clojars. This release fixes a client HTTP transport bug, adds utility fns and cleans up code. • Repo: https://github.com/plumce/plumcp • Changelog https://clojurians.slack.com/archives/C0ACL16QWAU/p1775490937177759 Please share your feedback/questions/followup in #plumcp or in thread.

https://github.com/replikativ/stratum/ is out — the big addition is a modular query planner with cost-based optimization. *What's new:* • IR-based query planner with predicate pushdown, zone-map annotation, operator fusion, DP join reordering, column pruning, and statistics propagation. Replaces the previous monolithic query routing with an explicit logical IR → optimize → physical IR → execute pipeline.. • Dictionary-encoded column predicates — string/keyword predicates on dict-encoded columns now use the fast chunked SIMD path. • Custom predicate functions via :fn operator — arbitrary (fn [value] boolean) filters, compiled into bytecode-generated masks. Primary use case: Datahike entity filtering via RoaringBitmap. • SQL conformance fixes — 8+ bugs found via PostgreSQL regression tests: SELECT without FROM, nested CASE in ELSE, empty window frames returning NULL, NOT IN with NULL (three-valued logic), self-joins with overlapping column names, and more.

core.async 1.10.870-alpha2 is now available (only relevant if you're using the flow alphas) • https://clojure.atlassian.net/browse/ASYNC-275 (CLJ) Fixed flow/futurize to retain original behavior of propagating exceptions
