  "description_en": "Binary analysis framework written in F# for .NET by KAIST's SoftSec Lab. It parses ELF, PE, Mach-O and WebAssembly files, parses, disassembles and lifts instructions into its own IR, recovers control-flow graphs and assembles code; the README's feature table covers x86/x86-64, ARMv7/AArch64, MIPS, PowerPC, RISC-V, SPARC, S390 and other ISAs as well as CIL, EVM, eBPF, WebAssembly and Python bytecode. Its b2r2 launcher starts a readelf-like format scanner, a linear-sweep disassembler, a recursive-descent explorer with a web GUI, an IR and assembly REPL and an assembler.",

    "Latest release at review: v0.10.1, published 2026-06-17, with BinExplore archives for Linux, macOS and Windows on x64 and arm64; libraries such as B2R2.FrontEnd.API and the B2R2.RearEnd.Launcher .NET tool are on NuGet at 0.10.1. The reviewed main commit (2026-10-17) is 1,231 commits ahead of that tag and still declares 0.10.1.",
    "Building needs the .NET 10 SDK or later, and the projects target net10.0. The README states that the core library has no external dependencies, while System.IO.Hashing, FSharp.Compiler.Service, FParsec, BenchmarkDotNet and Avalonia.FuncUI serve specific components; it presents the APIs as usable from F# and, in principle, other CLI languages, on Linux, macOS, Windows and other .NET platforms.",
    "Input is a user-supplied ELF, PE, Mach-O or WebAssembly file, or a raw byte image loaded with an explicit ISA. The README's feature table gives CFG recovery a full mark only for x86, x86-64 and EVM and a half mark for the other ISAs, lists no lifting, CFG recovery or assembly for TMS320C6000, and notes that some areas are still in progress.",
    "MIT license. The README cites the 2019 NDSS Binary Analysis Research workshop paper describing B2R2 and lists research papers that use or build on it."

    "审阅时最新版本为 v0.10.1，发布于 2026-06-17，提供 Linux、macOS 和 Windows 的 x64 与 arm64 版 BinExplore 压缩包；B2R2.FrontEnd.API 等库以及 B2R2.RearEnd.Launcher .NET 工具在 NuGet 上的版本为 0.10.1。所审阅的 main 分支提交（2026-10-17）比该标签多 1,231 个提交，版本号仍为 0.10.1。",
    "构建需要 .NET 10 SDK 或更高版本，各项目以 net10.0 为目标框架。README 称核心库没有外部依赖，System.IO.Hashing、FSharp.Compiler.Service、FParsec、BenchmarkDotNet 和 Avalonia.FuncUI 仅用于特定组件；README 还表示其 API 可在 F# 中使用，原则上也可供其他 CLI 语言调用，并可运行于 Linux、macOS、Windows 及其他 .NET 支持的平台。",
    "输入为用户提供的 ELF、PE、Mach-O 或 WebAssembly 文件，或按指定 ISA 加载的原始字节镜像。README 功能表中，只有 x86、x86-64 和 EVM 的控制流图恢复标为满月，其他指令集为半月；TMS320C6000 未列出提升、控制流图恢复和汇编支持，README 也说明部分功能仍在开发中。",
    "MIT 许可证。README 引用了介绍 B2R2 的 2019 年 NDSS Binary Analysis Research 研讨会论文，并列出使用或基于它的研究论文。"
