GreptimeDB's August 2026 monthly update introduces end-to-end support for Prometheus native histograms, an experimental service dependency graph from OTLP traces, and breaking changes in version v1.2.0-beta.2.
DuckDB v2.0 replaces its PostgreSQL-derived SQL parser with a PEG-based parser that is easier to evolve and can be extended at runtime.
DuckDB v2.0, codenamed Cyanoptera, previews new features including server mode, triggers, VARIANT type, asynchronous I/O, and a new SQL parser, set to release this fall.
