The devs are actively working on the ‘logseq database version’. It’s their current priority, so even though the master branch seems less active for the past months, you can see a lot of daily commits on the ‘feat/db’ branch here : Commits · logseq/logseq · GitHub
The db version will bring a lot of new features and perf improvements in the long run (types/classes, supertags, much faster, multiplayer/crdt). Some of the improvements also make their way to the current master branch.
