Flit-core

Flit-core provides a PEP 517 compliant build backend, encapsulating the core distribution-building logic for projects that use Flit for packaging. It is an essential dependency for the user-facing `flit` tool, enabling the creation of wheels and source distributions. The current version is 3.12.0, released on March 25, 2025, and maintains a fairly active release cadence with multiple updates throughout the year.
