ReSharper C++ 2026.2: C++26 Reflection, ISPC Language Support, And More - The JetBrains Blog

ReSharper C++ 2026.2 introduces significant advancements, including support for C++26 reflection, which allows compile-time introspection and code generation, though currently only supported by GCC 16. This release enhances the constexpr evaluator to handle dynamic memory allocation and constexpr exceptions, while also introducing consteval blocks and user-defined annotations for improved metaprogramming. Additionally, the update brings ISPC language support for high-performance parallel programming, particularly benefiting Unreal Engine projects with faster indexing and enhanced Blueprint support. New code inspections and refactoring tools, such as improved inline function usage and context actions for toggling const qualifiers, further streamline coding practices, and the release also emphasizes performance improvements in Unreal Engine projects, making startup and indexing significantly faster.
