Bug Fixes
Fix "accessor" name migrations
Renaming a table accessor (the name parameter in #[table] or [Table]) previously did not update the internal st_*_accessor tables during auto-migration. This caused a runtime panic on the next module call because the module depends on accessor names to invoke exposed ABIs. The migration system now detects accessor name changes and applies them.
(#5544)
Fix C# HTTP timeout clamp
The C# runtime's HttpClient.MaxTimeout was incorrectly set to 500 ms instead of the host-enforced limit of 180 seconds. C# modules performing HTTP requests via procedures would time out prematurely for any request exceeding half a second. The clamp now matches the host maximum.
(#5751)
Performance
C# runtime buffer reuse
C# module FFI exports now reuse buffers when consuming BytesSource values instead of allocating fresh byte arrays per call. Benchmarks show 3-29% speedups for iteration and argument deserialization workloads on .NET 10 NativeAOT-LLVM. This is safe as long as Wasm module execution remains single-threaded.
