Signed + notarized combined installer (Customize pane: Standalone app + AU / VST3 / CLAP, optional sample models & cabinet IR).
Fixes
Editor-teardown crash (important if you're on an older build). Adding the plugin to a track and then deleting it could crash the host (e.g. Ableton Live) — a use-after-free in the editor's display-link idle pump on teardown. AU v3 (macOS + iOS) now serializes editor teardown on the main thread, and the GPU render path re-checks liveness after the idle pump. Verified unaffected for VST3 / CLAP / Standalone.
A2 "Deluxe Reverb" sounded harsh. Packed SlimmableContainer A2 captures now default to the Lite variant, matching the reference. The larger Full variant is faithful but carries ~5 dB more high-frequency energy — great for a dark capture, harsh on a bright one. Pick Full anytime in Settings; an ⓘ explains the trade-off.
Output level. Output Mode now defaults to Normalized (−18 dBFS) so quiet captures don't invite over-cranking, and is a full Raw / Normalized / Calibrated selector.
Cabinet swaps are click-free (crossfaded), and the Settings panel label/control overlap is fixed.
