Everything that has changed
- Launch
DuckDB 1.4.0 becomes the first LTS release
DuckDB adopts a long-term-support line and adds database encryption and MERGE INTO. The LTS commitment is the more consequential half: it is the point at which running DuckDB as durable infrastructure, rather than as a notebook tool, stops being reckless.SourceLogged in the sqlite vs postgres vs mysql comparison
How this changelog is kept
Events are written by hand and dated to the day the change took effect, not the day we noticed. Each one names the tools it affects, so a shared change — a cloud provider raising egress prices across four products — appears on every profile it touches rather than being duplicated four times.
Everything here also flows into the site-wide changelog, which is the cross-tool feed of what is moving in developer infrastructure pricing.
