This release adds lean, deterministic ARC-style lifecycle behavior to the scripting engine. It cuts down your per-fragment script size dramatically while enabling automatic DOM removal of hydrated scripts and data when no longer necessary.
In addition to the above we've included several runtime quality-of-life upgrades.
Added
- feat: Integrate an ARC-style (Automatic Reference Counting) lifecycle to automatically release functions/data on DOM removal from injected
<Script>blocks.
Improved
- qol: Atomic style observer now detects deeply nested style shards via recursive traversal.
- qol: Bun and Node runtimes now fallback to
nullif version detection fails, aligningruntime.versionbehavior across runtimes. - qol: Workerd runtime now returns a 500 response if no incoming handler is registered, instead of returning
undefined.
What is ARC?
ARC (Automatic Reference Counting) is a memory management technique where objects are retained or released based on how many references exist to them.
In TriFrost, it ensures that each DOM-bound function or data payload is automatically cleaned up when no longer used, without relying on a garbage collector.
It’s deterministic, lightweight, and perfect for fragment-based hydration.
TriFrost continues to push toward a leaner, smarter edge, onward to 1.0.
As always, stay frosty ❄️
