New features in version 4.6
Released on August 29th, 2016

  • Code between special comments /*STUNNIX_COPYASIS_BEGIN*/ and /*STUNNIX_COPYASIS_END*/ is not mangled now.
  • Improved support for some language constructs and compatibility with modern C++ standard
  • Fixed support for some MSVC-specific constructs
  • GUI: Small improvements in GUI.
  • Various minor improvements have been made.

New features in version 4.5
Released on April 25th, 2016

  • Added support for obfuscating names of exported and imported in assembler source code. All files with .asm and .s extensions are handled as assembler source code files.
  • Now it's possible to preserve specified number of topmost comments (they usually contain copyright notices) in each file (use "--preserved-top-comments-count" command line option or corresponding setting in GUI).
  • Now it's possible to tell obfuscator to replace some strings containing name of single symbol with a string containing mangled version of that symbol, using --quoted-symbol-names command line option. GUI support for this option has been added too (new screen was introduced: Symbols ⇒ Edit strings that contains symbol names).
  • GUI: Now GUI allows to query list of absent, autoadded and missing files in Settings ⇒ For files; also on that page now it's possible to remove from the project all files that are absent in filesystem.
  • GUI: Now GUI can be run by several users on the same computer at the same time.
  • GUI: Now all symbol-editing screens in Symbols menu save symbols without leaving the screen. Added button for adding symbols extracted from directory with source files into Symbols ⇒ Edit user-specified exceptions in one click.
  • GUI: Added Build ⇒ Clear output & state files & rebuild all menu item. Now menu items Build ⇒ Rebuild * and test are visible only if testing command is defined.
  • Usage guides have been rewritten, they are much more clear now.
  • GUI: Small improvements in GUI.
  • Various minor improvements have been made.

New features in version 4.4
Released on March 22nd, 2016

  • GUI: Fixed problems with starting Project Manager GUI on computers with Windows 10.
  • GUI: Added ability to generate aliases for command line tools by installing wrappers via Tools ⇒ Configure command line tools... Use it to install aliases to obfuscator and other command line tools to any directory. It's recommended to install aliases to a directory, listed in your PATH environment variable - this way you won't have to specify path to command line tools when invoking them.
  • Added option twopasses to shortest symbol mangler. It allows to protect entire project in one invokation of the obfuscator (i.e. you won't need to invoke obfusctor two times, first in "counting symbols" mode, and then in "obfuscating" mode). It makes using the product from command line much easier when you need to produce as short version of the code as possible.
  • GUI: Generated buildscripts can now be queried for files that are neither registered in the project nor were auto-added to the project.
  • GUI: Tools ⇒ Command line builder now shows the command line on the same page, preserving current state of the form.
  • GUI: Now header files are detected in the project, and exceptions are loaded for them automatically.
  • GUI: Small improvements in GUI.
  • Various minor improvements have been made.

New features in version 4.3
Released on February 22nd, 2016

  • Added new mangler for symbols: mixcase. Given a set of replacement identifiers (e.g. just one topsecret), it will generate new symbols by altering case of characters in them, e.g. it will replace symbols with TOpSecREt, toPSecREt, tOPsEcReT and so on.
  • combs mangler for symbol names now won't have any hash collisions at all. In previous versions of the product, hash collisions forced user to change the seed and rebuild the project.
  • Added bin/extract-syms-from-dir.pl script to extract symbols from directory, doing same as Tools ⇒ "Extract symbols from directory with source files" does.
  • Added lib/generate-buildscript-from-op-file.sh - a script to generate buildscript from .op file. It's useful when .op files are kept in git.
  • Added lib/copy-stunnix-project-manager-mode-props.pl - a script to copy settings for some mode from one .op file to another .op file.
  • GUI: All structures in .op files and buildscript files have their keys sorted. This reduces number of changes between different versions of .op file, very useful if they are stored in git.
  • GUI: Now it's possible to use environment variables in paths for Project's Input, Output and State directories (use it like this: $ENV{PROJECTSDIR}/project214/in).
  • GUI: Added function for generating .bat version of buildscripts.
  • GUI: A lot of improvements in GUI, especially in build results window.
  • GUI: Now it's really possible to specify names of files with exceptions via mode settings.
  • GUI: Now it can handle projects with even hundreds of thousands of files without any issues (Windows command line length limits no more apply).
  • GUI: Generated buildscripts can now be queried for files missing in the project and for files that were autoadded to the project (using new command line switches).
  • Various minor improvements have been made.
