ISSUES FIXED IN IDA 9.0 BETA 2

 * IDA Home: cloud decompilers unusable
 * Replaced every reference to ida.key into ida.hexlic
 * IDA Linux installer creates a weird directory in the installers's directory
 * IDA Home: missing IDA Pyton module "ida_mergemod"
 * missing style dylib on macOS
 * decompilers: crash on navigation into non-decompilable function
 * asmtil: interr 918 + crash on filtering a large list of types
 * idapython: idc.get_ordinal_qty() not usable
 * added wasm loader and processor module


KNOWN ISSUES FOR IDA 9.0 BETA 1

 * IDA Teams server (vault) not yet available
 * IDA floating license server (licsrv) not yet available
 * Dialogs text in Linux installer not readable on Ubuntu with dark theme active
 * Linux installer creates empty directory named `***unknown variable
   uninstallerdirectory***`
 * iOS18 DSC objc analysis lacking out-of-box (__OBJC_RO has to be loaded
   manually for now)
 * IDA can crash on x64 macOS at file load time


HEADLESS PROCESSING WITH IDALIB

 * 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 engine is invoked from 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 RCP or IPC to an external IDA process means you get native speed of
   execution


WASM DISASSEMBLER AND FILE FORMAT LOADER

 * With many apps shifting to client-side browser applications we saw the need
   of 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 DISASSEMBLER AND DECOMPILER + MD1ROM LOADER

 * Both the MIPS disassembler and decompiler got added support for nanoMIPS
   instructions. The nanoMIPS support is included in the classic MIPS (HEXMIPS)
   decompiler, so there is no need to purchase an extra license.

 * Firmware compiled for nanoMIPS often ships in md1rom format, which is why we
   added an md1rom file loader to IDA (which includes parsing and applying of
   debug symbols, if available)


NEW RISC-V DECOMPILER AND DISASSEMBLER EXTENSIONS

 * 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)


C++ EXCEPTIONS SUPPORT IN THE DECOMPILER

 * 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++


IDAPYTHON IMPROVEMENTS

 * Most IDAPython APIs now have type annotations, making the API less
   obstructive to use.

 * Python virtual environments are now supported - simply point $PATH to the
   directory containing the interpreter inside the virtual environment (done
   automatically by the activation script).

 * Objects returned in the Python API are properly zero-initialized.

 * Auto-completion in IDA's CLI now disregards __magic_methods__ and
   auto-generated SWIG methods, which reduces noise and helps finding a
   particular function easier.


FLIRT UPDATES

 * We massively updated, modernized and extended the number of FLIRT signatures
   available for use with IDA. As of this release, we provide (and plan to
   maintain) signatures for the following operating systems, languages,
   architectures, and software packages:

 * Golang:
   
   * Versions: stable versions from 1.10.0 to 1.22.5 and unstable version
     1.23.0-rc1/1.23.0-rc2
   
   * Windows: x86, x64, arm, arm64
   
   * Linux: i386, amd64, arm, arm64
   
   * Darwin: amd64, arm64

 * C/C++
   
   * Windows (MSVC):
     
     * Architectures: arm, arm64, i386, amd64
     
     * Packages: ATL, CTL, MFC, Windows SDK 10, Windows SDK 11
   
   * Linux:
     
     * Distribution: Ubuntu & Debian
     
     * Architectures: i386, amd64, arm64, armhf, armel, arm, s390x, mips64el,
       mipsel, mips, ppc64el
     
     * Packages: libc6, libselinux1, libpcre2, libidn2, libssl, zlib1g, lib32z1,
       libunistring, libcurl4-gnutls, libcurl4-nss, libcurl4-openssl,
       libnghttp2, libidn2, librtmp, libssh, libssh-gcrypt, libpsl, libldap,
       libzstd, libbrotli, libgnutls28, nettle, libgmp, comerr, libsasl2,
       libbrotli, libtasn1-6, libkeyutils, libffi, uuid, libprotobuf,
       heimdal-multidev, musl, libplib, libsdl1.2-bundle (libsdl-console,
       libsdl-sge, libsdl1.2, libsdl-ocaml, libsdl-image1.2, libsdl-kitchensink,
       libsdl-mixer1.2, libsdl-net1.2, libsdl-sound1.2, libsdl-ttf2.0,
       libsdl1.2-compat, libsdl-gfx1.2, libsdl-pango), libsdl2-bundle (libsdl2,
       libsdl2-gfx, libsdl2-image, libsdl2-mixer, libsdl2-net, libsdl2-ttf)

 * The extra signatures are initially available as separate download


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 pre-9.0 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:



{
  "plugin" :
  {
    "name" : "greeter",
    "entryPoint" : "main.py"
  }
}




NO MORE IDA32

 * We deprecated IDA32 a few versions ago. With IDA 9.0, we’re unifying the IDA
   binaries targeting 32 or 64 bit code into just one IDA64 binary. This means:

 * Number of installed files is cut in half

 * Easier life for native plugin maintainers since only one version (__EA64__)
   needs to be maintained.

 * Conversion of IDB files to I64 file format is transparently and automatically
   performed by IDA64.


UI IMPROVEMENTS

 * The legacy Enums and Structures views are removed entirely and replaced by
   Local Types. This also means that struct.hpp and enum.hpp and their
   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 will be available for the release.

 * 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. By the same time, we added
   basic support for UI-based editing of argument locations, to make prototype
   syntax less of a hassle to remember.

 * It is now possible to specify fixed size for structures and to enable field
   packing easily

 * A refreshed set of shortcuts which better matches the modern OS conventions
   can now be selected instead of the traditional shortcuts

   in 32 bits)
 * BUGFIX: cvt64: converting an old .idb to .i64 would fail if its path
   contained a space

   and would refuse to run without it.
 * BUGFIX: navigating to a global name which matched a known type name would
   fail
 * BUGFIX: objc: NS*Block reference detection error would end up creating
   incoherent block structures over unrelated data
 * BUGFIX: PC: alloca_probe / chkstk_ms does not modify rsp or rax in x64 code,
   unlike x86
 * BUGFIX: PC: REX prefix could be incorrectly applied to 32-bit instructions
 * BUGFIX: PC: vmovw instruction was decoded as if using 16-bit registers (it
