Changelog

1.0.0

Initial LiteMapper 1.0 implementation completed against SPECIFICATION.md.

Public Mammoth.LiteMapper abstraction API, including mapper/configuration attributes, option enums, and LiteMapperCycleException.
Roslyn incremental source generator for compile-time C# object mapping with deterministic generated output.
Static, instance, extension-method, new-object, and existing-target mapper method support.
Flat, nested, collection, dictionary, enum, nullable, constructor, record, init, required, value-type, and recursive mapping support.
Explicit member configuration, ignore/default controls, local and registered converter resolution, default mapping selection, and configuration precedence.
Compile-time diagnostics for invalid declarations, unsupported mapping shapes, ambiguous mappings, invalid configuration, nullability, collections, existing-target mappings, recursion, enums, and internal generator failures.
Package layout for Mammoth.LiteMapper, Mammoth.LiteMapper.Abstractions, and Mammoth.LiteMapper.Generator, with analyzer assets kept out of consumer runtime output.
Package-consumer, trimming, Native AOT, API compatibility, deterministic package-content, generated-source, runtime, incremental, and capability validation.
Compiling Basic, Collections, and ASP.NET Core samples.
BenchmarkDotNet flat-object benchmark comparing manual mapping, LiteMapper, Mapperly, Mapster, and AutoMapper.
Source-backed usage guide at docs/USAGE.md.

Normal consumers install Mammoth.LiteMapper; the generator is delivered as an analyzer asset.
Supported generated paths use direct C# and no runtime reflection, runtime type scanning, dynamic dispatch, or runtime mapper registry.
Release-quality benchmark interpretation remains separate from the dry-run benchmark smoke validation recorded during implementation.
