IDA 8.5.250228, February 28, 2025

With IDA 8.5, we bring you some critical fixes, UI enhancements, and updates to the IDA API/SDK and IDB. IDA 8.5 will help users on perpetual terms gradually migrate to the IDA 9-series. Please mind that IDA 8.5 does not support features specific to the 9-series platform, such as x64 exceptions, IDA feeds and others.

Who Can Upgrade to IDA Pro 8.5?

If you have a license for IDA Pro 8.4 under active support, you are eligible to upgrade to IDA Pro 8.5.

How to upgrade to IDA Pro 8.5?

  1. Log in to the using the email address associated with your previous license. In the banner at the top of the Licenses tab, click Upgrade to IDA 8.5 Now to proceed.

  2. Your updated perpetual license should now appear in the list. Click the three dots under the Actions column, and select Download hexlic to get your new license file.

  3. Download the 8.5 installer via our and follow the steps in the .

IDA 8.5 Highlights

Important updates to be aware of:

  • The IDB file format has been updated. This means that IDBs saved with IDA 9.0 will be compatible with IDA 8.5.

  • The C++ SDK and IDAPython API have been revised. You may need to update your plugins to ensure compatibility with IDA 8.5. Check the porting guide under Developer Portal.

  • For floating license users, a new license server is required. You can download it from . The FlexNet server from IDA 8.4 will not work with 8.5.

Licensing changes

WASM Disassembler and File Format Loader

  • 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

nanoMIPS support

  • 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 convention

  • 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)

IDAPython Improvements

  • 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 annotations and docstring (if available) in a pop-up hint

No more IDA32

  • We deprecated IDA32 a few versions ago. Now, just one IDA binary handles both 32- and 64-bit code:

    • Thus, the number of installed executable files is cut in half.

    • Native plugin maintainers will have an easier life 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

UI Improvements

  • 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

Metadata Descriptors for Plugins

  • 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:

plugins
└── ida_greeter
    ├── ida-plugin.json
    └── main.py

A possible ida-plugin.json could look as follows:

{
  "IDAMetadataDescriptorVersion": 1,
  "plugin" :
  {
    "name" : "greeter",
    "entryPoint" : "main.py"
  }
}
  • This approach allows for easy management of plugin's resources and bundled dependencies

New license type and installers for all supported platforms (Windows/Linux/macOS). Note that IDA 8.5 requires a new license file to work. You can download the new .hexlic license via My Hex-rays .

A custom Hex-Rays licensing server replaces the FlexNet licensing server for floating licenses. The updated license server can be downloaded via . For more details about the new license server, check our

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 .
