radare2-2.7.0 -- SleepyNull

• http://radare.mikelloc.com/get/2.7.0/

This release brings a lot of improvements in the analysis and visual representation. Things like improved variable detection, types inference, extended jump tables detection are now enabled by default (see afta command for the variables and types inference). A lot of small fixes to make visual modes even prettier than before: Unicode support across visual modes and strings, bugfixes, and enhancements of the visual panel's mode, extended autocompletion. Big amount of these changes was brought in by our beloved Google Summer of Code students and external contributors.

There is one more notable big change - background tasks, improving the responsiveness of radare2 in visual mode and from r2pipe.

radare2-2.5.0 - eknad

Codename - eknad

Binaries: http://radare.mikelloc.com/get/2.5.0/

2.5.0

CodeName eknad

This release brought many small improvements to the existing commands and features, it improved different platforms support and cross-platform compilation. Moreover, integration with Cutter was also greatly enhanced. Thanks to new contributors visual modes (panels in particular) were polished to shine.

New Features

IO

There is an important addition in IO land: added gprobe plugin for communication with various parts from computer displays, based on Genesis/STMicro/MegaChips chipsets.

RopChain

Rop gadgets are (finally) stored in sdb, meaning that the search process will be much faster. And since they are now only searched once, and then stored, only the first search will take some time. The following ones should be instant!

Analysis

Radare2 gives a lot of power to the user to perforn manual analysis, hence why we're constanstly improving and adding features in this area. Like the new /g command, to find all possible paths from A to B inside a function. Moreover for the capstone analysis modules granularity assumptions were fixed to be handled properly.

GUI

Visual panels are now capable of using utf8 characters, so they are looking prettier. Especially with the color sheme support!

Misc and usability

As usual, more and more commands are now supporting the j suffix, to output JSON. We removed some dead code, memleaks, added some fixes, … you know, the usual drill. The ragg2-cc and ragg2 tools merged into a single binary. This should remove a lot of confusion and reduce the number of questions asked on our IRC chan :D. Since radare2 is a complex software, we're adding more and more autocompletion support in it! Please do open bug if you feel that we missed some subcommands.

Build system

You can now build radare2 with the meson build system. This should improve the build time.

Code cleaning

We moved x86.udis to radare2-extra, because we're using capstone as a main disassembler. You can of course still use UDIS if you prefer,
by installing it with r2pm: r2pm -ci udis86

File format handling

Radare2 is now able to parse RTTI for both GCC and MSVC

New commands

• Initial implementation of cmd.pdc to select pseudo-decompiler

This release became our pain in some parts of the body and a huge win. Thanks to condret, alvaro and maskray the long term refactoring on top of the simple IO library (siol) is now merged, tested and everything is rewritten on top of this layer.

radare2-1.6 aka Digital Lettuce

This release comes with major improvements in GDB Client/Server, Windows support, timeless debugger and many stability bugfixes. Also adds support for PPC VLE, Ethereum Virtual Machine, workaround to properly configure the disassembler on PlayStation2 ELFs and added support for the Hexagon CPU.

Strings displayed in the disassembly are now more readable and support multiple encodings, utf32 has been added, as well as latin1, utf8 and asciidot. So rabin2 -z will catch wide32 strings too!

Thanks to the GSoC guys we get:

• Windows: many stability fixes, msvc builds automated on each commit, installed done, a new command allows to grab all PDB from all linked libraries at runtime of any process and load the symbols into the disassembly.
• GDBserver support works, you can use r2 as a gdbserver, but also, many bugs has been fixed to support remote gdb-avr, arm and arm64, so you can now debug the Riscure crackmes without depending on GDB, and also natively debug Android apps thru the gdbserver protocol.
• New mechanisms for storing the debugger backstep snapshots is making it backstep much faster by using checksumming and storing diffing changesets instead of full dumps for each step. Better integration with the tracing commands of r2.
