Just giving people free time is not enough. I think we should foster the culture of volunteering more. Build infrastructure to make it easier and broader. Build spaces to explore. Some of the richest life experiences can come from that and it can make our society stronger and more connected.

I personally think we shouldn't work less hours but we should work less weeks. More time for side projects and volunteering.

You can now switch from internal to external isolate mode with untrusted code. Running untrusted code in an external process can provide an additional layer of security.

Also, did I mention that GraalWasm now supports untrusted code execution?

Polyglot isolates now ship with a new memory isolation technique called Monocle. Monocle is about 4x faster compared to the previous, fence-based mitigation.

My colleagues also published a wonderful paper about this:

The GraalWasm Java Embedding API has gotten a face-lift. It now works more similarly to the Wasm embedding API in JavaScript.

Here is an extensive migration guide:

All language and tool Maven artifacts are now OSS licensed! For example, the 'js' Maven artifact is now identical to the 'js-community' counterpart.

If you want extensions like sandboxing, you now need to depend on the 'truffle-enterprise' dependency explicitly.

Die Sicherheitsgarantien der USA sind neu. Darf man aber auch nicht überbewerten.

Es sind viel mehr Kinder betroffen als die meisten glauben. Man sammelt aber keine Daten dazu zumindest hier in Ö von Versorgung ganz zu schweigen. Kinder sind leider oft auch schwerer betroffen als Erwachsene. Unsere lokalen Betroffeneninitiativen werden überrannt mit Anfragen.
