SQLite 3.53.0 Released — ALTER TABLE ADD/DROP COLUMN, Query Result Formatter, and Major Internal Overhaul
Simon Willison's Blog·medium signal
SQLite 3.53.0 ships as a major release after 3.52.0 was withdrawn, accumulating significant user-facing and internal improvements. ALTER TABLE can now add and drop columns, and a new Query Result Formatter (QRF) provides multiple rendering options for SQL result tables with a playground demo. Simon Willison highlighted the release as 'a pretty big release with a whole lot of accumulated improvements.' For builders using SQLite as an agent memory store or embedded database, the ALTER TABLE changes reduce migration friction.
