v2.3.0 is released

New in the release - general usage

Log all calls to dp

There is now an easy way to inspect all calls to dp, which makes it easier to debug 3rd party tools.

New in the release - for Simulink users

Search Simulink models

It is now possible to search a Simulink model, either by name...

...or by specific properties. You can even use full regex if desired.

Add support for embedded test harnesses in Simulink Test

DiffPlug now has full support for embedded test harnesses, including diff. It's fine to add, remove, or rename harnesses or the block under test.

Auxiliary details

Every item in a Simulink diagram has details, which we show in the bottom left. New in this release, we can now show multiple sets of details for some kinds of item. For example, a subsystem block has a set of details for the block, and another for the subsystem itself:

Many of these items used to have their own entries in the model tree (for example configSet.xml), which caused the model tree to get cluttered. Although these items are somewhat hidden for the purposes of viewing, they are always fully expanded in diffs, to make sure that you don't miss any changes.

When viewing	When diffing

These changes were driven, in part, by the proliferation of auxiliary objects in Simulink Test harnesses and other recent Simulink features.

Diff config for auxiliary objects

This is the first version of DiffPlug which presents changes in the properties of the "system" and "chart" objects in each subsystem and stateflow chart. These objects are mostly backend noise - most meaningful changes to them show up in the blocks and states themselves. For example - Stateflow charts have a property which describes the "action language", but it's very rare that you can change the action language without also changing the states and transitions in your Stateflow chart.

Now that these auxiliary objects are displayed directly, we have added a System section to the diff filter config. When you load an old config, it will default to ignoring the purely-internal properties, but it will still show differences in cosmetic properties like "background color". You can use the normal diff filter config workflow to ignore these as well, if you like, and they are ignored by default in builtin/ignoreCosmetic.

Miscellaneous

• Added support for Simulink R2020a.
• Reading the diff of a single long property in a Simulink diff could be difficult / impossible, now fixed.
• Improved quality of Stateflow diff.
• Improved display of model workspace MAT-data.
• Older Simulink files using rare charsets such as ibm-5348_P100-1997 will now load without error.
• The Simulink detail title could be jumpy, now fixed.
• Simulink view, diff, and detail are all sorted alphabetically.

v2.2.1 is released

Fixed in this release

• Improved support and debug logging for proxy auto-config (PAC) scripts.
• Added support for SSL-inspecting firewalls.
• Fixed license manager gui on Linux.
• Misc user interface fixes.

v2.2.0 is released

New in this release - general usage

Easy mode

A new "Easy mode" was added which allows users to get started more easily.

Diff list extended with tabs for "Recently closed" and "Open now"

Also makes the DiffList easier to open and close.

Closed tabs can be restored

Previously open tabs are now restored on startup, and Ctrl+Shift+T will reopen a recently-closed tab (just like a web browser).

Text diff speed and quality improvement

Speed and quality of text diffs greatly improved, especially for non-western-language Unicode diffs.

Added support for TortoiseSVN

By introducing a new -flavor TortoiseSVN to dp ext. You can read more here.

New in this release - for Simulink users

Multiline properties are now displayed in full

In the viewer

and in the differ

Undock diagrams in the diff to spread across multiple monitors

This new command is called Undock diagrams across multiple monitors / Dock diagrams back to main window. It is a replacement for Spread across multiple monitors.

Wherever you put these undocked diagrams, DiffPlug will remember their position for other Simulink diffs, until you move the main DiffPlug window, at which point you will have to reposition them again.

Ignored filter is shown for additions and removals

You can now view and configure the ignored property filter from the detail diff of additions and removals (previously it was only shown for changes). These filters are also respected when dumping the properties of additions and removals into exported reports.

Report export now estimates report size

Improved diff config dialog and defaults.

Better layout, supports copy-paste, undo/redo, drag and drop, and more. The built-in properties ignored as "cosmetic" have added FontWeight and FontAngle for Simulink, and fontSize, drawStyle, midPoint, and labelPosition for Stateflow.

Fixed in this release

Fixed label parsing for Simulink action ports.
