Release 1 (R1): What Shipped

Release 1 is the first “stable foundation” slice of PyCauset: rectangular matrices, a real dtype system (including complex floats), a persistent on-disk container, and a semantic properties mechanism that can change algorithm choices.

This section summarizes the implemented user- and contributor-facing behavior, not the planning documents.

In this section

• Shapes & NxM matrices: R1 Shapes (NxM Matrices)
• Persistence & snapshots: R1 Storage (Persistence Container)
• Semantic properties: R1 Properties (Semantic Metadata)
• DTypes, promotion, overflow: R1 DTypes (Integers, Float16, Complex)
• Linear algebra endpoints: R1 Linear Algebra (Core Ops)

• NxM Support Status
• Storage and Memory
• API Reference
• Internals
• Dev Handbook
