Review details

Systems and components

• observed — changelog.d (service) was modified; 3 changed files map to changed impact.
• observed — CHANGELOG.md (service) was modified; 1 changed file maps to changed impact.
• observed — src (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in CHANGELOG.md: Adds the 2.4.2 fixed entries for acronym, alphanumeric, and non-ASCII naming; convention mapping into non-default initial values while leaving mapper-bound and [MapFrom] members alone; and generator compatibility behavior for netstandard2.0/.NET Framework targets without ModuleInitializerAttribute and language versions below C# 9.
• observed — Modified behavior in CHANGELOG.md: Adds the changelog entry that generated mappers dispatch non-exact runtime types to the engine, except for sealed types, and documents the NativeAOT NotSupportedException when the derived pair is undeclared.
• observed — Modified behavior in CHANGELOG.md: Adds the changelog entry that array-to-List<T> mapping no longer reuses source elements, with MSG001 and engine fallback when the element class cannot be generated; interface destination elements are likewise refused with MSG001 and mapped through the engine.
• observed — Modified behavior in changelog.d/naming-conventions-word-splitting.fixed.md: The changelog entry describing naming-convention matching and MapWithConvention behavior was removed.
