version: "v1.6.0"
title: "Release Loro v1.6.0"

Snapshot import speed is now 2x.

This is implemented by skipping the scan when importing a snapshot, which avoids running the decompression during the import process (but we need to ensure the parent-child link is still accessible in Arena). It also skips the checksum check in the import_all method on MemKV because we already check the checksum in the header of the snapshot/update.

## v1.0.0 vs v1.6.0
