GraphForge v0.3.7: Function Coverage visual summary

Open Source release

GraphForge is Curate Labs work, released through the DecisionNerd open-source organization. This post is a release note for embedded graph tooling and analytical Python workflows.

GraphForge v0.3.6 was a correctness release focused on temporal semantics and TCK accuracy.

The release notes report +813 net new passing TCK scenarios, moving from 1,694 to 2,507 passing scenarios.

What Shipped

  • TCK harness fixes for integer property comparison and map literal coercion

  • Correct `date({})`, `datetime({})`, and `time({})` map constructors

  • ISO 8601 duration and datetime parsing fixes

  • Timezone offset and IANA timezone parsing

  • Date truncation units including week, quarter, decade, century, and millennium

  • Duration serialization, comparison, multiplication, and fractional arithmetic

  • Anonymous relationship patterns and label predicates in WHERE

Why it matters

Temporal correctness is notoriously fussy. This release made GraphForge more faithful to Cypher semantics while also improving the harness used to prove that correctness.
