Cutter 2.0.1

This release updates Rizin to 0.2.0 and brings a few additional fixes on top of Cutter 2.0.0.

Known Issues

• Windows build can't load certain resource #2667

Changes

• Updated Rizin to 0.2.0
• Updated jsdec to 0.2.0 and rz-ghidra to 0.2.0
• Fix path when building appimage, caused by #2574
• Set macOS deployment target to 10.14 Mojave for compatibility. (#2650)
• Removed build.sh (#2654)

Cutter 2.0

This is the first official release of Cutter since its backend has been changed from radare2 to Rizin.
Last r2 compatible commit can be found at d813b7a, there are no plans to further maintain r2 compatible branch by Cutter developers.

This version of Cutter is built with Rizin 0.1.1.

The accompanying blog post highlights some of the features below in detail: https://cutter.re/cutter-2.0

Features

• Support new Projects in Cutter that will allow saving and opening project files.
• Add a command line flag for loading projects #2606
• Improve the workflow of renaming functions, flags and more #2468
• Improve the remote debug dialog #2472
• Add reverse debugging support. (Note that debugging is still in a preview state)
• Support trackpad pinch gesture #2453
• Add comment column to multiple table views #2441
• Add option for displaying basic block address at the start of each block in CFG #2482
• Reworked disassembly arrow drawing #2559
• Add a preview-on-hover functionality in disassembly widget #2459

Platform compatibility fixes:

• Fix build on CentOS 7 with GCC 4.8 #2492
• Haiku OS build #2485
• Note: there is no official native macOS M1 build but most parts of Cutter, except debugging, work fine using Rosetta2.
  Building Cutter natively for arm64 on M1 from source is however fully supported.

Bugfixes

• Fix macOS release package not running without having gettext installed from homebrew. #2547 #2474 #2456 #2447 #2428
• Resolve bug with line highlighting #2218

Build system, packaging and development changes

• The default build options changed to use bundled Rizin. If you are a package maintainer see https://cutter.re/docs/building.html#making-linux-distribution-specific-packages
• The root CMake file is now located at the root of the repository instead of the src/ directory. This slightly changes the build instructions
• Fully transition to CMake as the only build system. Remove qmake and meson projects.
• Large parts of packaging logic moved from CI scripts to being done directly by build system.
• macOS release package is now ad-hoc signed, this should help with the running of the debugger. It doesn't help with developer identity warning when opening the package or debugging system or AppStore programs not marked as debuggable (just like any other debugger regardless of how it's signed).
• Development has switched to using clang-format for code formatting.

Cutter 1.12.0

Highlights

Decompiler

In this release, we introduce major improvements to the Decompiler feature in Cutter. These improvements couldn't be made without the help of our team member and GSoC student @NirmalManoj 👏

• Context menu interactions with the decompiler are now context sensitive, only relevant menu items are shown and they applied to the item that was clicked
• Decompiler based Syntax Highlighting in the Decompiler widget (old highlighting mode can be chosen in appearance options)
• Support opening multiple Decompiler widgets at the same time. Each of the instances can be set to show different decompiler (Ghidra, RetDec, r2dec, ...) and different functions.
• Make the current-address synchronization consistent with rest of widgets

Known Limitations

• The new features in the Decompiler work best with r2ghidra, not all of them are implemented for r2dec
• Some hacky features, like instruction patching, that were available in the previous context menu are not available in the new one and might be added in the future.
• Decompiling large functions using r2ghidra causes UI to freeze temporarily

Radare2

• Cutter 1.12.0 depends on radare2 4.5.1

Other

• Support analysis after opening the file
• Configurable analysis options from the Preferences widget
• Local variables X-Ref view

The Arctic World Archive

On February 2, 2020, GitHub will capture a snapshot of every active public repository, to be preserved in the GitHub Arctic Code Vault. This data will be stored on 3,500-foot film reels, provided and encoded by Piql, a Norwegian company that specializes in very-long-term data storage. The film technology relies on silver halides on polyester. This medium has a lifespan of 500 years as measured by the ISO; simulated aging tests indicate Piql’s film will last twice as long.
