I think `BEGIN CONCURRENT` is on its own branch: https://www.sqlite.org/src/vdiff?branch=begin-concurrent https://www.sqlite.org/src/vdiff?branch=begin-concurrent The `wal2` mode is on its own branch and you have to compile it specifically. It'd be great if they merged it into the main branch though. https://www.sqlite.org/cgi/src/doc/wal2/doc/wal2.md https://www.sqlite.org/cgi/src/doc/wal2/doc/wal2.md
