Release v0.7.0 – multi-database support, more resilience, even better performance, improved documentation

immudb is getting faster and stronger! This release brings new features, even better performance and more resilience to immudb!

Summary of the most relevant points:

  • Multi-database support (you can run many databases with one immudb server to separate data or to provide multi-tenancy)
  • Enhanced user management (per database)
  • Automated service and data recovery in case of unexpected OS or container crashes
  • Improved service management for Microsoft Windows
  • 100+ times faster cryptographic proofs (we completely revised and optimized the methods for entry validation; but don’t worry, the API methods didn’t change)
  • Improved documentation for gRPC and structured value

Thanks for the amazing community feedback and contribution!
