Summa 2.0.0

Summa 2 brings the current Rust search engine into the original Summa repository,
with a consistent namespace across libraries, clients, binaries, deployment
configuration, metrics and documentation.

Packages

• Rust: summa-core, summa-proto, summa-server, summa-broker, summa-tool,
  summa-mal, and summa-tokenizer.
• npm: summa-wasm and summa-client-typescript.
• PyPI: summa-client-python and summa-mal (source distribution).
• Container: ghcr.io/spacefrontiers/summa/summa-server:2.0.0, containing the
  server and broker binaries.

Upgrade

Upgrade clients, servers and brokers together: RPC service names now use summa
and summa.broker. Update imports, command names, environment variables,
monitoring configuration and deployment names. Browser storage and training
artifacts use the new namespace.

The immediately preceding 1.9.1 search-index encodings and TQ fingerprints are
preserved. Original Summa 0.x indexes require rebuilding from source documents.
See the migration guide.

Documentation

The blog retains the original
articles with targeted factual corrections and adds tutorials on
dense retrieval
and sparse retrieval.
