Jun 1, 2026June 2026 (2026-06) focused on delivering high-value features for content access, improving stability, and maintaining cross-platform reliability in the duckdb/community-extensions repository. Key feature work includes offline/remote content access via the ZIM extension, with a read_zim() table function, projection pushdown, lazy content reads, and metadata accessors, plus multi-file reads and binary-safe VARCHAR outputs. ZIM was upgraded to v0.2.0 and then to v0.4.x, introducing zim:// virtual filesystem, full-text search (zim_search), title suggestions (zim_suggest), and a warm handle cache for remote streaming. Webbed extension saw multiple version bumps (2.1.x → 2.2.x) with stability improvements, an out-of-memory (OOM) regression guard, platform adjustments, and compatibility enhancements to align with DuckDB 1.5.3/1.6 main. The DuckHunt extension was updated to 1.10.0 to maintain DuckDB v1.5.3 compatibility and includes a WASM test harness for improved testing. Platform-level changes included Windows exclusions for several extensions to avoid vendored fmt/MSVC issues, ensuring green CI and predictable releases. The Duck_Tails extension was bumped to v1.4.2. Overall, these changes enhance data accessibility, reliability, and cross-platform support while maintaining alignment with the DuckDB ecosystem.
