DiffPlug.

New in this release:

• When external changes are detected in an open file, DiffPlug will now refresh the editor rather than open a file status dialog. If you have made changes to the file, the file status dialog will be displayed as before.
  • If you prefer the old behavior where a file status dialog was displayed whenever an external change was detected, this can be enabled from the “Help -> Preferences” window.
• DiffPlug’s “new version available” notifier now allows you to ignore a specific update.

Bugs fixed in this release:

• Fixed a bug introduced in 1.2.0 which affected saving Simulink .mdl files.
• Fixed the error message that was sometimes displayed when very different Simulink models were compared.

New in this release:

• Editing and merging of Simulink embedded MATLAB functions and blocks.
  • DiffPlug 1.2.0 should not be used to edit MDL files. 1.2.1 is a bugfix release that addresses this issue.
• Added export information (ERN, ECCN, CCATS, etc.) to the manual.
• Windows explorer extension is now optional.
• Diffs can now be opened by dragging a file and then dropping it on top of the file with which you would like to diff.
• Files can now be added to the DiffList by dragging them onto the DiffList icon.
• Folder names must now end in a slash.
  • C:/path/ signifies a folder named “path”, while C:/path signifies a file named path.
• Autocompleter dropdowns are now translucent and more responsive.
• Archives (.zip, .tgz) can now be opened directly.
• Simulink files can now be opened / diffed from within an archive file.

Bugs fixed in this release:

• Fixed explorer.exe crashes that affected a few XP users with specific conflicting software.
• Fixed a bug introduced in 1.1.0 which caused the Simulink differ’s colors to stop updating dynamically in response to ignored properties.
• Fixed a bug which made it impossible to open Simulink models with pre-R2008a Goto blocks.
• Fixed a bug which made it impossible to open a folder in a zip file which doesn’t contain explicit folder entries.
• Fixed a minor visual layout bug in the folder viewer.
• Various UI fixes related to right-click popups.
• Various UI fixes to the image viewer and differ (better hover detection, better keyboard shortcuts).

New in this release:

• Powerful signal tracing
  • We’ve added the ability to trace not only one signal, but all the inputs and outputs of a block.
  • Includes intelligent handling of
    • Goto and from
    • Subsystems, inports, and outports
    • Enabled, triggered, and function call subsystems
    • If / else and case subsystems
  • All for free!
  • Also added the ability to extend a trace arbitrarily deep (traces ordinarily end at the first non-virtual block)
    • This is advanced functionality which requires a dp.simstate.differ license
• Stateflow transitions now display their execution order
• Full support from R2008a to R2013b
• KeyRing is now searchable

Bugs fixed in this release:

• Fixed a memory leak in the Simulink parser - much faster for large models than before!
• Fixed several display bugs related to special subsystem ports (enable, trigger, function-call, etc.) and how they react to block rotation and mirroring.
