Breaking changes

🔐 Eval usage is now disabled by default

To prevent potential security issues, StylesheetCodec.allowEval is now false by default.

🌐 Configurable i18n

The built-in Translations class is no longer used by default. If you want to keep using it, you must now explicitly enable it:

GlobalConfig.i18n = new TranslationsAsI18n();

🧰 Utility functions access changes

Several utils have been reorganized for better clarity and maintainability:

• These functions are now accessed through specific namespaces:
  • get, getAll, load, post, submit → requestUtils
  • error, popup → guiUtils
• The old utils namespace has been removed.
• Remaining relevant properties were moved to guiUtils.

💥 Removed internal functions

Some functions that were mistakenly exposed as public have been removed:

• Utils.copyTextToClipboard is no longer available.

  See #738

• cellArrayUtils.filterCells was removed - just use the native Array.filter() instead!

  See #752

Highlights

🎯 New: Fit Center

You can now center and fit your graph into the container with the new FitPlugin.
The method is inspired by the former example provided in the JSDoc of Graph.fit() but improved to:

• handle margins better,
• reduce visual shifts when called multiple times.

The storybook and TypeScript example have been updated to showcase how it works in various contexts.

🌍 Configurable i18n support

Until now, the Translations class was always used internally. Now you can:

• Disable i18n completely for smaller bundles,
• Plug in your own i18n solution.

This makes maxGraph more flexible and lighter by default.

📦 Smaller bundle size

Thanks to the new i18n configuration, tree-shaking now works better.
Depending on your setup, you could reduce the size of your app by 5-10kB - and probably more with tuned bundler configs!

🔬 Examples in the maxGraph repo

📖 See documentation for what each example includes.

🔬 Examples in maxgraph-integration-examples

All integration projects reuse a shared core similar to ts-example. Here's the app size:

[1] parcel is the sole bundler that increases the size of the application. Parcel was bump from 2.13.3 to 2.14.4 which may have introduced changes.

➰ New story: curved edges

We've added a story to show the difference between:

• default edges
• curved edges
• rounded edges
