SochDB v0.4.0 Release Notes

Release Date: January 12, 2026

🎉 Major Changes​

Project Rename: ToonDB → SochDB​

SochDB v0.4.0 marks a significant milestone with the complete rename of the project from ToonDB to SochDB. This change affects all aspects of the project:

What Changed​

  • Package Names: All crates renamed from toondb-* to sochdb-*
  • Type Names: All types updated (e.g., ToonDB → SochDB, ToonTable → SochTable, ToonValue → SochValue)
  • Module Names: Internal modules renamed (e.g., toon:: → soch::)
  • Python Package: Renamed from toondb to sochdb
  • URLs and Domains: Updated to sochdb.dev and github.com/sochdb/sochdb
  • Query Language: ToonQL renamed to SochQL

What Stayed the Same​

  • TOON Format: The TOON serialization format name remains unchanged (similar to JSON, it's an established format name)
  • toon-format crate: External crate dependency kept as-is
  • Core Architecture: All the sync-first design and performance optimizations from v0.3.5 are preserved
