3.3.3 / published May 18, 2026 / repository
Crystal language implementation of the OpenCog framework. A complete rewrite of the OpenCog artificial intelligence system in Crystal, providing better performance, memory safety, and maintainability. Database dependencies can be disabled at compile time using environment variables: DISABLE_SQLITE3=1 - Disable SQLite3 support (requires libsqlite3-dev) DISABLE_POSTGRES=1 - Disable PostgreSQL support (requires libpq-dev) DISABLE_ROCKSDB=1 - Disable RocksDB support (requires librocksdb-dev) When all database backends are disabled, use MemoryStorageNode or FileStorageNode.
Documentation is being built
Nobody had asked for this version before, so its documentation is being built now. Documentation is built the first time a version is requested rather than ahead of time for every version ever published.
