: The functions window and structures window now support better nesting and filtering, which is critical when dealing with multi-gigabyte modern game binaries or massive OS kernels.
The API layers have seen refinement to match the internal 64-bit structural shifts:
One of the silent but powerful updates is the type system. IDA 8.x struggled with modern C++ constructs.
The licensing model has been updated to offer significantly more flexibility. Licenses are no longer bound to a specific operating system. With one IDA license, users can now run the software on any of the three supported platforms (Windows, Linux, and macOS). Furthermore, a custom Hex-Rays licensing server has replaced the FlexNet server for floating licenses, and IDA Teams now enforces concurrent usage rather than limiting the number of named users.

This release had been anticipated for some time. In the months leading up to September, Hex-Rays published a series of blog posts teasing the major features arriving in IDA 9.0, including nanoMIPS support (September 26), the new FLIRT Manager (September 24), and C++ exceptions in the decompiler (September 5).
Coinciding with the 9.0 release line, Hex-Rays transitioned away from perpetual, platform-locked software keys into a modernized, cloud-forward Subscription Licensing Model .
The graphical user interface has transitioned from Qt5 to PyQt6/Qt6. : The functions window and structures window now
New dedicated decompilers for 32-bit and 64-bit RISC-V code (HEXRV and HEXRV64) were added.
Testing was performed on a standard RE workstation (AMD Ryzen 9 7950X, 64GB RAM, NVMe SSD).
The unified ida executable handles both legacy 32-bit and modern 64-bit databases, automatically detecting bitness and converting legacy databases to the new 9.0 format seamlessly. The licensing model has been updated to offer
New disassembler capabilities to support client-side browser applications.
