v2.0.2 is released

New in this release

  • The content of Simulink DocBlocks can now be opened in the viewer (windows only for now).
  • An in-progress git clone can now be cancelled.
  • Git squash now works on a larger variety of commit topologies.

Fixed in this release

  • Fixed intermittent warning when closing the command console.
  • Fixed several zombie thread issues.
  • Fixed many small bugs in the git client, including:
    • Double-clicking the commit button could cause two commits.
    • Editing an old commit message would sometimes not update in the repository view.
    • Many minor fixes.

v2.0.1 is released

New in this release

  • As a security measure, if a git repository redirected you to a new URL, DiffPlug would refuse to disclose your password to the new URL and instead give an error. This error now includes a one-click "update this repository URL" to improve the workflow.

Fixed in this release

  • Fixed a parsing warning related to some stateflow transitions which crossed through subcharts.
  • Fixed a bug when accessing git repositories at the entity console without a trailing slash.
  • Fixed a bug where git repository credentials would sometimes need to be entered more than once.

v2.0.0 is released

The long wait for DiffPlug 2 is finally over! DiffPlug 2 streamlines the features from DiffPlug 1, and allows us to explore new capabilities that were impossible with DiffPlug 1.

DiffPlug 2 does not need to be installed, you can run it from any folder, and you can run it in parallel with an existing 1.x install without breaking it.

Many of the changes in DiffPlug 2 are about reorganizing DiffPlug 1's features, you can get an overview of them over at migrating from 1.x to 2.x. The list of changes below only covers new features and deprecated features - it doesn't include all the streamlining and simplification that happened between 1 and 2.

Improved Simulink support

  • 3-way diff is now possible for the first time in DiffPlug
  • DiffPlug now supports MATLABĀ® R11 through R2019a, compared to just R2008a through R2017a for 1.8.10
    • Note: support for R11 through R2008b is provisional, full compatibility is guaranteed only for R2009a forward
  • Opening a Simulink file now takes half as much memory than in DiffPlug 1.8.10
  • Diffing two Simulink files now takes 17x less memory than in DiffPlug 1.8.10
    • The quality of Simulink diffs has also been improved dramatically

This feature has not yet been exposed to users, but it is now also possible for DiffPlug to modify a Simulink model. This will allow full merge in a future release.

Temporarily removed, but coming back

There are a few features that we were not able to include in DiffPlug 2.0, but they will definitely return in future versions of DiffPlug.

  • editing text files (currently view-only)
  • exportable Simulink diff report
  • archive decompression
  • Synergy CM support
  • Amazon S3 support

Permanently removed

32-bit operating systems

The last version of MATLAB to support a 32-bit operating system was R2015b. Many of the software systems that DiffPlug is built on top of have announced end-of-life for 32-bit operating systems.

Windows XP

DiffPlug uses many of the same libraries as the Eclipse Java IDE. The latest release of Eclipse has dropped support for Windows XP. The minimum required version is now Windows Vista.

Subversion

Git's dominance in the version-control industry makes it difficult to justify maintenance and upkeep on our subversion integration.
