I saw it a couple of days ago.

The most interesting thing is the support of ARM V8.3 instructions, specially the PAC (Pointer Authentication Code).

Looks like when you load an IOS12 kernelcache the function pointers are resolved corretly.

Also includes stack unwinding in code using PAC instructions.

But for me the most interesting adition is really the new processor module for PIC24 and the extended support of some more PIC 16Fx variants.

They just need to add now a PIC C decompiler for make me happy.

also the new decompiler supports C++ objects, inheritance and methods pointers. Amazing

  • + ui: "Binary search" now allows tabs instead of spaces, between different items (e.g., 0x89\t0xE5), allowing easier copy-paste from tools such as GDB
  • + ui: API: adding navband ea_t <-> pixel conversions
  • + ui: added shortcuts Ctrl+Shift+Up/Ctrl+Shift+Down to jump to the start of the previous/next function

  • BUGFIX: hexrays: in some cases "smod power2" rule could produce wrong operands in the generated microinstruction
  • BUGFIX: hexrays: in some cases the decompiler could lose 'default:' branch of a switch statement
  • BUGFIX: hexrays: in some rare cases some comparisons would be decompiled incorrectly
  • BUGFIX: hexrays: incorrect partial operand propagation in some rare cases on Big Endian platforms
  • BUGFIX: hexrays: offsetof(type,field) may have empty field name in some rare cases
  • BUGFIX: hexrays: pc: incorrect handling of loope/loopne instructions
  • BUGFIX: hexrays: signed modulo 2 was sometimes recognized with wrong size
  • BUGFIX: hexrays: some 64bit comparisons would be decompiled wrongly
  • BUGFIX: hexrays: stack pointer could be miscalculated when decompiling a mixed range that contained code both inside and outside functions
  • BUGFIX: hexrays: the "lxe_lvar_type_changed" could provide outdated lvar_t information
  • BUGFIX: hexrays: the BACKPROP_CC rule could invert an 'if' condition
  • BUGFIX: hexrays: the rule "~x > 0" => "x <= 0" was too aggressive
  • BUGFIX: hexrays: the type of guard_dispatch_icall() coud interfere when guessing the protype of the called function
  • BUGFIX: when calling 'set_member_tinfo()', the struc_member_changed event would be sent before the tinfo_t object is actually applied
  • BUGFIX: when parsing omf files ida was storing wrong extdef name length in the idb
  • BUGFIX: when using the "Suspend on debugging start" option with the mac debugger, /usr/lib/dyld would be missing from the module list
  • BUGFIX: win32: ida was mistakenly setting a borland debug hook in some cases; this would change the program execution
  • BUGFIX: win32: if the debugged application erased a software breakpoint, appcall would stop working
  • BUGFIX: windbg: IDA could crash with interr 1491 when loading a 32-bit minidump of a process with DLLs loaded above the 2GB mark (0x80000000)
  • BUGFIX: wrong function prototypes could cause an interr
  • BUGFIX: 68000: ida would not truncate function and instruction addresses to 24-bit

  • BUGFIX: debugger: win32: IDA could crash on win10 preview with interr 1419 when debugging a 32-bit process
  • BUGFIX: fixed interr 40372 (ida would die if a conditional bpt was present in the idb and idapython was disabled or not present)
  • BUGFIX: hexrays: if multple windows with the same function were present, an inactive one could be used for jump targets
  • BUGFIX: mips: fixed delay slot processing
  • BUGFIX: print_operand() would print data operands incorrectly for big endian processors (this function is not used to generate the disassembly listing)
  • BUGFIX: IDA could crash when trying to open a registers view in the GDB debugger
  • BUGFIX: enumplace_t::adjust() was not working properly with bitfields + serials
  • BUGFIX: ios debugger was broken for old iOS versions (< 9.0)
