DevSnapshot: 6.2.0-beta.6

May 15, 2026

Polyphase Engine 6.2.0-beta.6 is a momentum release. Instead of chasing one flashy headline, this update tightens the workflows developers touch every day: faster native addon iteration with DLL/SO runtime upgrades, broader shader and shadow pipeline support, and new SignalBus + controller API capabilities that make tooling and automation easier to scale. Just as important, 6.2.0-beta.6 ships with serious stability work across addon reloads, packaging, cross-platform builds, and editor/runtime edge cases. The result is simple: less friction, fewer surprises, and more room to build ambitious features without fighting the engine.
