❗ Breaking changes

• Due to significant changes in payload format, collections created with the previous engine version are not compatible with the new version. The most straightforward migration approach would be to re-create collections with the latest version from scratch. Breaking changes are required to make our v1.0 release as legacy-free as possible. Hope for your understanding.

🔬 Work-in-progress

• Our main efforts are now focused on the distributed deployment feature. Stay tuned a check out our Roadmap for details.

Breaking changes are required to make our v1.0

so, there won't any versions with broken backward compatibility, in foreseeable future at least?
