IDA 9.0.240925 September 30, 2024
Licenses are no longer bound to a specific platform. After buying one IDA license, it can be used on all supported platforms (Windows/Linux/macOS).
License packs with various decompilers are available
IDA Home 68K is retired and replaced by the new IDA Home RISCV (with cloud decompiler!)
IDA Teams and Private Lumina functionality are available as options and can be used with standard IDA Pro
IDA Teams users count is no longer limited by the seat count — only the concurrent usage is enforced according to IDA's license type
A custom Hex-Rays licensing server replaces the FlexNet licensing server for floating licenses
With idalib, both the C++ and Python APIs can be used from outside IDA to form standalone applications. The resulting program or script doesn’t have to be loaded inside IDA, but rather IDA's engine is used inside your application.
This makes developing against the IDA API much easier — if configured correctly, you get auto-completion and debugging in your favorite C++/Python IDE
NO RPC or IPC to an external IDA process means you get a native speed of execution
Almost any Python can be used: official CPython, Anaconda, Homebrew, etc.
New decompilers targeting 32- and 64-bit RISC-V code (HEXRV and HEXRV64) are now available
We extended the RISC-V processor module to support T-Head extension instructions (used in Xuantie and Allwinner processors)
With many apps shifting to client-side browser applications, we saw the need for a new disassembler for Web Assembly (WASM)
WASM code is embedded into its own binary file format hence we also ship a file loader that decodes the WASM file format
Both the MIPS disassembler and decompiler now support nanoMIPS instructions
Despite the name, it's not a simple extension of the MIPS ISA but a completely new encoding of the existing MIPS instructions and addition of new ones, as well as a brand new calling convenion
nanoMIPS support is included in the MIPS decompiler (HEXMIPS), there is no need for an extra license
Firmware compiled for nanoMIPS often ships in md1rom format, which is why we added md1rom file loader to IDA (including parsing and applying of debug symbols, if available)
The decompiler can now emit try/catch blocks. As the first step, we implemented support for the C++ exception scheme in binaries compiled for x64 using Microsoft VC++.
Most IDAPython APIs now have type annotations, making the API less obstructive to use.
Python virtual environments (venvs) are now supported - simply run IDA from an activated virtual environment and it will pick up locally installed modules
Objects returned in the Python API are properly zero-initialized.
idapyswitch can now be used with read-only IDA installations (nothing is changed in the installation directory when picking a different Python version/install)
Auto-completion in IDA's CLI now disregards __magic_methods__ and auto-generated SWIG methods, reducing noise and helping to find a particular function faster
Auto-completing a method call shows its prototype with type annotaions and docstring (if available) in a pop-up hint
We deprecated IDA32 a few versions ago. With IDA 9.0, just one IDA binary handles both 32- and 64-bit code.
The number of installed executable files is cut in half
An easier life for native plugin maintainers since only one version (__EA64__=1) needs to be maintained
The conversion of legacy IDB into the I64 file format is transparent and automatically performed by IDA
The legacy Enums and Structures views are removed entirely and replaced by the Local Types.
It is now possible to specify fixed size for structures and to enable field packing easily
The function prototype editor (aka Y shortcut on a function name) now can toggle between the classic free-text one-line editor and a new multi-line editor featuring the usual shortcuts and controls.
At the same time, we added basic support for UI-based editing of argument locations, to make our custom __usercall syntax less of a hassle to remember.
The basic function prototype editor now indicates invalid prototypes via a red rectangle while typing
A refreshed set of shortcuts that better matches the modern OS conventions can now be selected instead of the traditional shortcuts
We massively updated, modernized and extended the number of FLIRT signatures available for use with IDA
Signatures for modern languages like Golang and Rust, as well as updates for classic compilers (MSVC for Windows, GCC for Linux) are made available as a separate download due to their size
These signatures are generated and updated automatically with every new release of the compiler/language/library
A new plugin (FLIRT Manager) allows easy application of multiple signatures to the database and lets you see which one gives the best results
ida-plugin.json now offers a standardized entrypoint for plugins. This enables plugin authors to follow their own plugin directory structure, all they need to do is point IDA to the main plugin entry point. To maintain backward compatibility, IDA will keep loading plugins in the legacy way for a couple of releases.
With the following directory structure:
A possible ida-plugin.json could look as follows:
This approach allows for easy management of plugin's resources and bundled dependencies

BUGFIX: UI: fixed missing scrollbars in the "Output" window when long text was printed
BUGFIX: UI: large amounts of lines in the "Output" window could cause slowdowns
BUGFIX: UI: long strings could be truncated when using "Export data"
BUGFIX: UI: when using COLOR_INV color code (e.g. in a custom viewer), IDA would use default color for the text instead of the previous background color
BUGFIX: UI: quick filters would apply to hidden columns
This also means that struct.hpp and enum.hpp and their Python counterparts ida_struct and ida_enum disappear from the API. Replacement functionality for both headers/modules is now located (mostly) in typeinf.hpp / ida_typeinf. A porting guide .
