DuckDB connections now share a single instance with multiple connections, advisor output groups lints to cut response bloat, and realtime v2.133.0 ships across platforms.

supabase/etl now reuses one DuckDB instance with a pool of connections instead of spawning separate instances per connection, cutting overhead and adding deferred durability in the SYNC phase plus a deadlock fix that also recreates the pool after maintenance [1]. This is an improvement, not a behavior change for callers. The MCP server's `get_advisors` response groups lints so repeated findings no longer repeat the same `title`, `description`, and `remediation` strings hundreds of times, shrinking the response payload [2]. supabase-js v2.113.0 adds realtime support to wait for pg changes, building on the canary released a day earlier [3]. slim-services shipped realtime v2.133.0 for linux/amd64, linux/arm64, and darwin/arm64 with a multi-platform Docker image [4]. A BEAM fix preserves explicit distribution overrides like `none` in Mix release env files, preventing native launches from detaching host `epmd` daemons [5]. UI library adds a backend-only MCP server block that exposes user-scoped MCP tools via an Edge Function [6]. Docs updates correct the API key rotation steps and restructure the API keys guide to separate context, procedure, and reference material [7][8].
