IDA Pro 9.1 (250226) with SDK and Utilities

The Hex-Rays Team has released IDA Pro 9.1 (250226) is a renowned software program utilized for reverse engineering binary code. As a disassembler and debugger, it enables users to delve into the intricate details of executable files, including executables, shared libraries, object files, and firmware. With its support for diverse processor architectures and file formats, IDA Pro proves to be a versatile tool for code analysis across various platforms.

Whst's new in IDA 9.1 (250226) - Data: February 28, 2025
This release begins to tackle a number of our 2025 product goals like expanding architecture support for non-mainstream chips and boosting collaborative features, specifically quicker sync cycles within IDA Teams.

Below is a highlights and you can read the detailed release notes here

IDA 9.1 Highlights

Smaller, Faster, Better: IDB Compression with zstd
IDA now uses zstd compression in IDB files.
- The higher compression results in smaller IDBs for faster saving and loading, especially when working with large databases.
- This also improves performance when working with remote storage or syncing with version control.
Sharper Disassembly & Analysis: Processor Module Updates
- TMS320C6 – The compact (16-bit) encodings from TMS320C66x and TMS320C674x series are now disassembled.
- RISC-V & RH850 – Improved switch table recognition, broader relocation handling, and extended register tracking.
- TriCore – mfcr/mtcr instructions now use symbolic names for Core Special Function Registers (CSFRs) when known, making code easier to read.
Debugger Updates: Time Travel, Intel Mixed Mode Debugging, and IPv6 Support
- Windbg Time Travel Debugging – You can now use Time Travel Debugging (TTD) with Windbg, allowing you to track and replay the execution of your code (requires an updated version of dbgeng.dll).
- Wow64 Process Debugging – You can now switch between 32-bit and 64-bit modes in Wow64 processes (aka Heaven’s Gate) - this can be debugged now.
- IPv6 Addresses – Our (debug) servers now speak both IPv4 and IPv6 (we hear you, sysadmins).
Expanding Decompilation: Latest Updates for ARM64, PPC, and RISC-V
We’ve made improvements for decompiler support across multiple architectures. These updates bring more precision and (hopefully) fewer headaches:
- ARM64 – Now supports ILP32 mode, making decompilation more accurate for systems like Apple’s watchOS.
- ARM64 – Displaying of symbolic system register names in pseudocode means better, more readable decompilation for OS-level applications.
- PPC – Support for EFP (Embedded Floating Point) extension instructions of the Signal Processing Engine (SPE), expanding your analysis capabilities.
- RISC-V – Added more intrinsics, reducing the number of __asm fragments in your pseudocode for a cleaner view. The decompiler now also handles Atomic Memory operation (AMO) instructions seamlessly.
Smarter Versioning with IDA Teams
Keeping your IDB versions in sync just got faster and more efficient.
- IDA Teams versioning functionality can now send and receive small binary delta files instead of whole IDBs, delivering faster version management operations and less network traffic by only sending what has changed.
- The delta files can also be stored on the Vault server, keeping down disk usage.
Automated Rust Version Detection & FLIRT Signature Generation
- IDA now detects the Rust version of the loaded binary, enabling the automated creation of custom, version-specific FLIRT signatures.


IDA Pro as a disassembler is capable of creating maps of their execution to show the binary instructions that are actually executed by the processor in a symbolic representation (assembly language). Advanced techniques have been implemented into IDA Pro so that it can generate assembly language source code from machine-executable code and make this complex code more human-readable.
The unique Hex-Rays Decompiler, which has been developed in response to the need of hundreds of IDA users, is the fruit of more than ten years of proprietary research. Thanks to the speed and scalability of its core algorithms, Hex-Rays does not merely break new ground in the well known C/C++ decompilation problem: it lays foundations for future developments in the field of binary analysis. Hex-Rays SA also expands the power and flexibility of its decompiler through the addition of several new algorithms and by offering an SDK as part of its package.
