Py2neo version 1.6 has been released, introducing node labels as a key feature that allows nodes to be tagged with keywords for categorization and indexing. The new release also includes a complete rewrite of the underlying HTTP/REST mechanism, enabling better support for streaming responses and incremental JSON decoding, which improves the handling of query results and batch requests. Additionally, Neotool has received updates, including full Unicode support, Cypher execution, and XML conversion options. While Cypher transactions are not included in this release due to technical challenges, Py2neo 1.6 is a valuable companion to Neo4j 2.0 and can be obtained from PyPI, GitHub, or ReadTheDocs.
