• Specify minOS to 10.0 on iOS builds

Android

• Added RAnalOp.datatype
• Improved Dalvik ESIL emulation

Thumb/ARM/ARM64

• Improved aap (function prelude analysis)
• Fix ARM64 assembler for MSR/MRS instructions
• Fix assembling for “b 0” on arm64
• Improved pseudo disassembly/decompilation for some more instructions

• Added aht to change opcode type hints
• anal.noncode variable has been removed completely, now anal.in=io.maps.x
• Added mips64 calling convention information and register profile
• Improve anal.eobjmp (bug spotted after almost killing iosections)

Build/Portability

• Fix build and improve support for WSL (linux-on-windows thing)
• Switch to capstone-master, the other branches change too frequently
• Add an option to disable the ptrace-wrap layer
• Implement debug process status in OpenBSD
• Keep supporting capstone3

Threads

• Implement T=&, & Po and many more

• Properly autoname import trampoline functions without anal.autoname

WebAssembly

• Fix conversion f32.const or f64.const
• WebAssembly improvements in branch lines and namings

• Expose the WASM exported symbols
• Initial support for atomic instructions

Disasm/Hex/Graph

• Added graph.few to
• Mips variable information is now displayed inside the MIPS disassembly
• Improve infinite loop instructions support (better ascii art, analysis info, search command)
• Added c1 command to compare bits between two different addresses
• Support hex.compact in pxa, improved 2 dimensional visual mode
• Added pgm command to print visual gadgets
• Add more clippies

Types/FunctionSignatures

• tfc – manage function calling conventions in real time
• Added function signatures for darwin (improve disasm output on mac/ios)
• Class information out of analysis is now saved in SDB and uses events
• Added bbsum and vars metrics for zignatures
• Add support for typedef
• Added several more function signatures for macOS and iOS
• Shorten local var and type names

Exploiting

• ragg2 now supports appending strings
• Implement visual rop gadget mode

Search

• Fix  – Implement /c[vV][j] /cej to search for code immediates
• Fix – Implement /ai to search for infinite loop instructions
• Implement /a1 to find all instructions by changing 1 byte

Binaries

• Added new command iF to show binary hashes (honors bin.hash)
• Support .plt/.plt.sec in ELFs
• Improve support when loading Sega Genesis binaries

Refactorings

• Kill r_json API
