Ubuntu 20.04
Downloaded and extracted the files into ~/DiffPlug

Try to start DiffPlug in terminal by calling the dp command in terminal
~/DiffPlug/: . dp

No lockfile found at /home/josef/.diffplug/.lock
Can’t find a running or installed DiffPlug.

Makes sense since it the fist time i run the program and there is no file “/home/josef/.diffplug/.lock”

What should i do?

New in this release - Simulink

• Added support for .sldd files (details).
• Some blocks with custom mask drawing code had their background and foreground colors set to white. Because DiffPlug can’t read all custom mask code, white-on-white is invisible, so the foreground color is now drawn as grey for these cases.
• When the label of a constant block is too long to fit, DiffPlug tries shrinking the font by 1 or 2 points.

Fixed in this release - Simulink

• Stateflow blocks whose ports have been reordered are now drawn in the correct position - no more unnecessary wire bends.
• Various bugs around drag-and-drop on the DiffList have been fixed.

New in this release - Simulink

• Added support for R2022b.

New in this release - general usage

New in this release - Simulink

• Added support for Simscape.
• Added support for R2022a.
• Added support for Stateflow entry and exit ports (introduced in R2021b).

Fixed in this release - Simulink

• Toggling the split direction while in the undocked state no longer causes an error.
• Previously, a diff filter such as subviewS/* would fail to apply on an empty subviewS node - it falsely assumed there would be a subviewS/someProperty=foo. This is now fixed, which reduces noise in diff reports, especially related to embedded MATLAB scripts.

New in this release - general usage

• Keyboard shortcuts for tab navigation.
• Ctrl+W to close the current tab.
• Ctrl+Shift+T to reopen a recently closed tab.
• Ctrl+Tab / Ctrl+Shift+Tab to navigate through tabs (or Ctrl+PgUp/PgDown).
• Instead of “Accept commits”, you now get “Accept 4 commits” (as appropriate).

Fixed in this release - general usage

• log4j has been entirely removed from DiffPlug.
• We used version 1.x which was not vulnerable to log4shell (see also this eclipse writeup as we share many dependencies).
• Dragging and dropping changed files in the commit diff viewer is fixed.
• When uploading a new branch to a remote, the --set-upstream tracking information wasn’t being saved to disk. Now fixed.
• On MacOS only, DiffPlug startup could hang on proxy configuration when no network connections were available. Now fixed.
• Viewing and diffing folders which filenames containing [...] has been fixed.

I’m not sure if the error is due to my install method, the lockfile or something else.

New in this release - general usage

• When you mouseover the head branch, you now get a context-sensitive popup for downloading and uploading against that branch.
• 
• It is now possible to force-push a remote branch backwards (usually not a good idea to do that, DiffPlug will ask for confirmation first).
• 
• git push now includes --set-upstream.

Fixed in this release - general usage

• Confirm dialogs which are triggered by the sync pane now automatically have keyboard focus.
• Faster feedback when removing a branch or tag from git tips.
• “Show help whenever I open a new git history window” was not respected, now it is.
• Cloning a git repository could sometimes fail starting in 2.6.0, now fixed.
• Deleting remote branches and downloading branches which have been removed from the remote are now fixed.
• Attempting to git push and getting rejected because the remote has new commits now proactively prompts to download latest.
• Retry attempts which needed a --force were broken, now fixed.

New in this release - expert users

• Whenever you see a red X like below, you can right-click it to open a stacktrace dialog. In previous releases of DiffPlug, this was double-click, but now it is right-click. This change was needed to allow us to use the red X as a regular button in some important places, namely the git operation tracker.

My current pain involves signal logging. I haven’t figured out how to use the Simulink.Diff to detect changes in Signal logging. Can diffPlug see this change?

If you make a really simple model. Then make a copy, and add signal logging to one signal. Then diff them… you don’t see the difference. Even if you remove all the configured ignore criteria.

Can you please add this!

I’ve recently purchased a license and I find myself struggling to set up a global installation availalbe to all users on a given machine. Could you please give me some tips?

I can run DiffPlug myself, but other users cannot. The other users get this error:

[test123.user@smaug2 ~]$ dp ext -before Control_Variables2_old.slx -after Control_Variables2_master.slx 
No lockfile found at /home/test123.user/.diffplug/.lock
Install beacon /home/test123.user/.diffplug/installBeacon indicates installation at /usr/local/DiffPlug/2.5.0
Launching /usr/local/DiffPlug/2.5.0/DiffPlug
...
Fatal: /home/test123.user/.diffplug/.lock

The error log file is quite large, with information on the various libraries in the path and similar.I can e-mail it if requested (to avoid copy/pasting it here due to large size)

In any case, I am not happy about my setup b/c I cannot run DiffPlug without the “installBeacon” file in /home/username/.diffplug/ which I have to create manually. My set up is as follows:

• OS is CentOS 7

• downloaded DiffPlug_linux_x64_2.5.0.tgz and extracted its contents into /usr/local/DiffPlug/2.5.0

• set up a soft link /usr/bin/dp -> /usr/local/DiffPlug/2.5.0/dp

• created directory /home/username/.diffplug and placed a file installBeacon in there with the following content:
  /usr/local/DiffPlug/2.5.0

• The license is activated for this machine (called smaug2). Nobody else is using DiffPlug at the same time during the tests.

  Many thanks in advance!

Regards,
Vadim

• It is now convenient to use user activation (aka floating license) without ever setting a password. So long as you select “user activation” DiffPlug will automatically return and pull licenses from your pool even if you use copy-paste activation.
• We have improved the license management ergonomics for fleets of air-gapped computers.
• Improved error logging and debugging info, especially for unresponsive UI.

New in this release - for Simulink users

• Added support for R2020b and R2021a.
