Memgraph 3.14's breaking changes will break column-position parsers — release notes double as a regression checklist

JeremyCMorgan · x · 2026-10-31

Jeremy Morgan warns that Memgraph 3.14 changes how nulls compare, how bound variables match, and what SHOW TRANSACTIONS returns — parsing output by column position will break. Key breaking changes: profile changes inside explicit transactions are now refused; SHOW TRANSACTIONS gains a database column; edge index operator metrics were merged into new total metric names. Rebuild modules on every upgrade to avoid production crashes. For AI agents: docs are available via llms.txt, .md URLs, and a key-free docs MCP server.
