v1.1.1

Fixed

• Added safe constant emission for MapFrom and UseValue values including enums, primitive values, nullable primitives, DateTime, DateTimeOffset, and Guid.

v1.1.0

Added

• OctoMap.Testing package with DI registration helpers, async mapper adapter APIs, configuration validation helpers, projection helpers, and mapping assertions for profile tests.

v1.0.0

Added

• Initial OctoMap solution structure based on DynaBee.
• Library, test, benchmark, documentation, package, and CI scaffolding.
• Stable NuGet package metadata, package icon, SourceLink, deterministic builds, symbols, and release workflow support.
• Dependency injection registration through Microsoft.Extensions.DependencyInjection.
• Public abstraction-first API with internal runtime implementations.
• Profile-based configuration with explicit fluent maps.
• Convention-based single-source mapping by matching readable source properties to writable destination properties.
• Runtime implicit single-source map creation with compiled map caching.
• Interface-based registration through IMapFrom<T> and IMapTo<T>.
• Attribute-based registration through [MapFrom], [MapTo], [MapName], [NullSubstitute], [IgnoreMap], and [MapConstructor].
• Explicit multi-source maps into a single destination through CreateMultiMap<TDestination>() and SourceSet.
• Multi-source member expressions through a source context for destination members that combine values from more than one source.
• Nested object mapping with cached generated child mapper calls.
• Flattening by convention for single-source maps.
• Destination path mapping through ForPath(...).
• Existing destination mapping overloads for in-place updates.
• Null source preservation and null collection handling options.
• Arrays, lists, sets, read-only collection interfaces, and collection element mapping.
• Global expression-based type converters and DI-based runtime converters.
• DI-based value resolvers, value converters, and lifecycle actions.
• Conditional mapping through PreCondition(...) and Condition(...).
• Constructor mapping for immutable DTOs and records.
• Reverse map registration for basic reversible single-source rules.
• Base map inclusion and polymorphic lookup support.
• Open generic map registration and lazy closed-map resolution.
• LINQ projection support through ProjectTo(..., mapper.ProjectionBuilder).
• Projection parameter replacement for captured MapFrom(...) values.
• Eager mapping compilation APIs for startup warmup and fail-fast validation.
• Configuration organization APIs for explicit profiles, map scanning, filters, duplicate policies, and diagnostics.
• Map plan diagnostics through GetPlan(...), DescribeMap(...), and DescribeConfiguration().
• Expanded BenchmarkDotNet scenarios for runtime, compile, projection, resolver, converter, collection, constructor, nested, and flattening paths.
• OctoMap.Analyzers package with map attribute and runtime-only projection diagnostics.
• Competitive benchmarks against AutoMapper and Mapster for flat, cold compile, startup compile, nested, collections, constructor, flattening, and projection scenarios.
• Optimized warm single-source mapping with typed generated mapper invocation, per-registry generic map caching, context-free execution, generated child-map dependency calls, and a per-generic fast slot that avoids concurrent cache lookup on the hot path.
• Optimized collection mapping generation by caching source collection counts and generating arrays for read-only destination collection interfaces when applicable.

Notes

• Multi-source maps are intentionally explicit and are not created implicitly at runtime.
• Runtime DI resolvers, runtime DI converters, lifecycle actions, conditional mapping, nested runtime mapping, and multi-source maps are not supported by LINQ projections.
• NativeAOT/mobile-friendly generation is not part of this release.
