Current development snapshot — Patch 292¶

20 August 2026

Patch 292 is the current full-handover baseline and is functionally identical to Patch 291. It includes three focused Driver dialog and enclosure-model improvements made after the previous Patch 288 baseline.

Driver & enclosure improvements¶

The Driver Parameters dialog now enables enclosure fields according to the selected enclosure type. Irrelevant values are disabled but retained, so switching between enclosure types is non-destructive.
Bass-reflex tube diameter and tube length are now bidirectionally linked. Either value can be edited, and KFilter6 calculates the other analytically from Vb and Fb.
Ql now affects sealed-enclosure damping in the simplified SPL path, full-circuit SPL path and impedance model. Vented and band-pass behaviour is unchanged, and Open Baffle remains independent of Ql.

Project and driver file formats remain unchanged:

.kfp project format v10
.kfd complete driver-slot format v2
tube diameter remains the persisted tube dimension; tube length remains derived

Other notable capabilities represented by this snapshot include:

versioned JSON .kfp project format v10 with legacy project loading
complete .kfd driver-slot format v2
measurement correction and FRD export
complex active-filter processing
Baffle / Diffraction with finite-piston averaging and left/right 45° chamfers
width-anchored low-frequency production blend for rectangular diffraction
experimental Floor Reflection stage
interactive Network Preview
project PDF export

Internal maintenance milestone¶

The maintenance series leading to Patch 288 replaced the historical flat passive-network array with a structured private eight-section model and completed the encapsulation of driver state and response caches.

These changes are primarily maintainability work and are not intended to alter saved project semantics or established simulation results.
