IDA Pro 9.0 (specifically build 9.0.240930, often referred via its internal build numbers like 91250226) is a major milestone that transitions the world’s leading disassembler to a unified, 64-bit-only architecture across Windows, macOS, and Linux. Key Highlights of IDA Pro 9.0
Unified Architecture: The "64" suffix has been dropped; there is now just a single ida executable that handles both 32-bit and 64-bit databases.
Headless Processing (idalib): A major new feature allowing developers to use IDA as a library. This enables running IDA's analysis engine programmatically in standalone C++ or Python applications without a GUI.
RISC-V & WASM Support: Introduction of a new native RISC-V decompiler and a dedicated WebAssembly (WASM) disassembler and loader.
FLIRT Signature Manager: A new "IDA Feeds" system and FLIRT Manager that automates the application of thousands of updated signatures for modern languages like Golang and Rust.
C++ Exception Handling: The decompiler can now reconstruct and display try/catch blocks, significantly improving the readability of complex C++ binaries. SDK and Utilities Update
SDK Modernization: The SDK now requires C++17 and has undergone significant changes to support the unified architecture. Binary-level compatibility with older versions is lost, meaning all third-party plugins must be rebuilt for 9.0. ida pro 91250226 win mac lin ux sdk and utilities upd
IDAPython Enhancements: The Python API now includes type annotations, support for virtual environments (venvs), and improved auto-completion in the CLI.
Updated Tooling: The idapyswitch utility now supports read-only installations, and the SDK includes idalib.hpp for hosting IDA functions externally. Licensing and Platform Changes
Cross-Platform Licensing: IDA 9.0 introduced a unified licensing model where a single key works across Windows, macOS, and Linux.
Subscription Model: Hex-Rays transitioned from perpetual licenses to a subscription-based model with this release, which has been a major point of discussion in the community.

The guide you're referring to likely highlights IDA Pro 9.0 (Build 91250226), a major update released on September 30, 2024. This version introduced a shift to a subscription-only licensing model and a unified binary that no longer separates 32-bit and 64-bit versions. Key Features of IDA Pro 9.0 IDA Pro 9
Platform Flexibility: A single license now works across Windows, macOS, and Linux.
Headless Processing (idalib): Allows you to use IDA's C++ and Python APIs outside of the GUI to build standalone automation tools. Decompiler & Disassembler Additions:
RISC-V: New decompilers for 32-bit and 64-bit RISC-V code.
nanoMIPS: Full support for nanoMIPS instructions and the md1rom file format.
WASM: A new disassembler and loader for WebAssembly modules.
C++ Exception Handling: The decompiler can now reconstruct try/catch blocks for x64 binaries compiled with MSVC. CVE-2024-3008 (Fixed) : A buffer overflow in the
FLIRT Manager: A new plugin for bulk-applying and managing signature libraries, significantly speeding up initial analysis. SDK and Utilities Updates
IDAPython Enhancements: Added type annotations for better IDE support, virtual environment (venv) support, and zero-initialized C++ objects.
Metadata Descriptors: Plugins can now use ida-plugin.json to define their entry points and directory structures.
SDK Porting Guide: Because of the removal of legacy "Enums" and "Structs" widgets in favour of Local Types, many headers were consolidated (e.g., into typeinf.hpp). Developers must use the Official Porting Guide to update existing plugins.
Visual Studio Templates: The SDK now includes templates to help kickstart the development of new plugins and loaders. IDA 9.0 | Hex-Rays Docs
