Highlights

Welcome to IDA 6.9!
Below are the highlights:
  • The biggest news is the ARM64 decompiler, a long awaited tool.
    We are proud that it works well and can handle floating point and even some NEON instructions.

    Input:

    Output:

  • We reworked the way we handle the navigation in the user interface and many related things. Now it is possible to synchronize between views, use the navigation history in structure and enum views, etc. Overall the user interface is more responsive.
  • Our oldest processor module for x86 got improved to decode many new fancy instructions
  • We switched from PySide to PyQt; from Qt4 to Qt5; from VS2010 to VS2015.
    All these changes are mostly internal but using newer libraries and development tools should improve your experience with IDA.

    • IDA doesn't recognize the IDAPLG environment variable anymore: the more versatile IDAUSR should be used instead
    • IDAUSR environment variable can hold more than 1 path, which will be searched in order when looking for files

  • User Interface
    • ui: added functionality to synchronize between user-specified viewers

    • ui: added support for multiple keyboard shortcuts per action
    • ui: "search all" can now be used in "Structures", "Enums", and any user-created viewer
    • ui: proximity view: double-clicking on an edge will take you to the node at the other end of the edge
    • ui: proximity view: it is now possible to see details about paths, and copy their information
    • ui: traced instructions are now highlighted in debug mode
    • ui: Ctrl+DblClick on name in idaview opens target in the new view
    • ui: Add syntax highlighting to Import/Export of colors + reset it when "Reset" button is pressed

  • Scripts & SDK
    • IDC: added PrintLocalTypes()
    • SDK: added PR_OUTER that must be specified for processor modules that support outer operands
    • SDK: event hooks: changed the way new event listeners are registered. now new listeners are appeneded to the end of the list and therefore will receive events last. hopefully it will lead to better logic because usually it is the ui and the processor module who will get first hooked; and only then plugins. it means that the processor modules and ui will be first to react to the events
    • SDK: functions to retrieve the input file size
    • SDK: functions to calculate/retrieve the SHA256 hash of the input file
    • SDK: introduced the notion of 'ABI name' in IDA; it can be set using set_compiler2() function; processor modules are in general responsible for recognizing it and setting up various config bits in IDA accordingly
    • SDK: added new flag: SETMENU_FIRST: add item to the beginning of menu (to be used in attach_action_to_popup)
    • IDAPython: IDP_Hooks, IDB_Hooks, UI_Hooks & DBG_Hooks are now automatically generated from the list of notifications in the corresponding .hpp headers

    • BUGFIX: RVCT-produced DWARF info with duplicate typedefs could cause the DWARF plugins some issues
    • BUGFIX: Selecting an area, pressing 't' to choose between matching structs (or almost-matching structs), and requesting to "Add missing fields" to a struct that would otherwise match, could crash IDA

    • BUGFIX: IDAPython: execute_ui_requests() could crash IDA
    • BUGFIX: IDAPython: on linux, some form-related controls could fail to show, because of pointer conversion issues
    • BUGFIX: IDAPython: retrieve_exceptions()/store_exceptions() was not usable because of unknown vector type
    • BUGFIX: It was impossible to override a core action's shortcut(s) to "no shortcuts"
    • BUGFIX: It was impossible to place breakpoints in source-level debugging with actual source files (i.e., not pseudocode provided by Hex-Rays)
    • BUGFIX: Jumping to 'linked node' (by pressing Ctrl+Up/Down) in the graph view, would correctly move to the target node, but wouldn't create a new location history entry
    • BUGFIX: Jumping to end of "Structures" view could fail to display the members of the last structure (if it is expanded.)
    • BUGFIX: Menus & toolbars were created after the PLUGIN_FIX plugins were initialized, and thus it was impossible to, e.g., attach_action_to_menu() from idapythonrc.py
    • BUGFIX: Moving left/right on a line where a search result was found, could lead IDA to fail subsequent "search again" operations (i.e., Ctrl+T)
    • BUGFIX: Navigating back & forth in a view that has a corrupt history could cause INTERR 40464 or 40465
    • BUGFIX: Opening an IDA 6.8 IDB with empty bookmarks in IDA 6.9, could cause INTERR 1312
    • BUGFIX: PE: intentionally corrupted .NET files could trigger invalid memory reads
    • BUGFIX: Pressing <Enter> in the "Select file to disassemble" could, in some cases, crash IDA
    • BUGFIX: Pressing Alt+L wouldn't provide visual feedback as it did before
    • BUGFIX: Separators in menus could, on some platforms, be prepended by '(...)'
    • BUGFIX: THREAD_EXIT event during appcall would cause problems
    • BUGFIX: The title of the Xrefs dialog that shows when pressing 'x', could be erroneous
    • BUGFIX: When loading an IDB and/or starting/stopping a debugging session, the main window could be maximized, but the widgets would remain in the top-left corner
    • BUGFIX: When pressing 'Down' in the "Structures" window, it might happen that the last line of a non-collapsed union would repeat multiple times
    • BUGFIX: calling idaapi.del_hotkey() twice with the same argument could crash IDA
    • BUGFIX: dwarf: be more resilient when saving a type to the TIL fails because of duplicate names
    • BUGFIX: fixed interr 40208 that could occur when closing the database after a fatal debugger error (disconnection from the remote host, for example)
    • BUGFIX: forms could not display filenames containing chinese characters
    • BUGFIX: non-ascii characters in the input file name would not be displayed correctly
    • BUGFIX: setting memory based variable values from the watch and locals view was broken
    • BUGFIX: spc700 processor data references could be missing
    • BUGFIX: structs with embedded arrays could be erroneously displayed in terse form even when it was not possible
    • BUGFIX: text IDA: pressing Ctrl+F4 to toggle to hex dump wouldn't refresh the screen right away
    • BUGFIX: text version of IDA could display the cursor in the wrong place if there was horizontal scrolling on the view
    • BUGFIX: text version of IDA could fail to draw the cursor after pressing 'End' to get to the end of a line of disassembly
    • BUGFIX: text version of IDA could fail to update the horizontal scrollbar upon cursor moves
    • BUGFIX: the wrong font might be selected when re-opening the font selection dialog
    • BUGFIX: win32 debugging: a hardware breakpoint located at an instruction right after another instruction that also has a breakpoint, could fail being triggered
    • BUGFIX: windbg could fail to load dbgeng.dll under Windows 7
    • BUGFIX: decompiler: arm64: in some cases condition flags could be calculated incorrectly
    • BUGFIX: decompiler: arm64: v8 was erroneously used to pass function arguments
    • BUGFIX: decompiler: arm: some conditional instructions could be translated without conditions
    • BUGFIX: decompiler: moving the mouse around could interfere with the "current location", and some actions could act in the wrong place (e.g., placing comments.)
    • BUGFIX: decompiler: stack arguments could not be recognized..., improved calculation of stack bytes used in a function call..
    • BUGFIX: decompiler: fixed numerous interrs (most of them very rarely occurring)
