Full Release Notes

- **fixed:** Escape backslashes and double quotes in `Content-Disposition` filenames to prevent header parameter injection in `Attachment` and `FileStream` ([#3664])
- `vpath!` macro now stops the compilation if your path is using deprecated path variables in the old `107` format, such as `:var` and `*var`. the only allowed way now is `{var}`. ([#3618])
- **fixed:** Return specific error message when multipart body limit is exceeded ([#3611])
