| `v0.2.0` | 2026-03-08 | Low | ContextDB is now schema-agnostic. The database starts empty — consumers define their own tables with `CREATE TABLE`. Immutability and state machine constraints are declared per-table, not hardcoded. The CLI REPL supports psql-style `\dt`, `\d`, `\?`, `\q` commands alongside dot-style commands.  ### What's new  - **Runtime table metadata registry** — tables and constraints are created at runtime, not compiled in - **Declarative constraints** — `CREATE TABLE ... IMMUTABLE` and `CREATE TABLE ... ST |
| `v0.1.0` | 2026-03-08 | Low | **Full Changelog**: https://github.com/context-graph-ai/contextDB/commits/v0.1.0 |
