New in Loro: Mergeable Containers! Concurrent Map child container creations no longer overwrite. This surprising overwrite issue existed in Loro, Yjs, and Automerge. Happy to finally ship a solution!

The fix: make the child ID independent of the creation OpId. We reuse Loro’s Root Container idea: identity from a unique string. For mergeable children, that string encodes the parent LoroMap + key, so both peers derive the same ID.

Root cause: normal child Container IDs include an OpId. So if two peers create a child container concurrently, they get different IDs. When both write to the same LoroMap key, one child can overwrite the other.

The Loro Protocol repo is now open source! It contains documentation for the wire protocol, along with TypeScript and Rust implementations of WebSocket clients and servers. The protocol allows reusing a single connection to join multiple CRDT rooms, such as Loro documents or the Ephemeral Store.

Loro Inspector is here! Now you can directly browse the current state and complete edit history of your Loro documents in the browser. You can also use this tool to time travel to any version in the history of your Loro document.

New version control primitives have been added to Loro: - diff(from, to): calculate the differences between any two versions - revertTo(version): Generate ops to revert to the target version - applyDiff(diff): Apply differences You can use them to implement functions like git squash and revert.
