Release notes

SMACC is pre-1.0

SMACC has not reached a stable release. Settings files, marker codes, the interface, and behavior may change between releases, and there are no compatibility shims. Pin one version for the duration of a study. See the versioning policy for what the numbers mean.

0.1.1 — 2026-06-15

Fixed the Analyzer vanishing on open — clicking Analyzer hid the launcher but never showed the Analyzer window.

0.1.0 — 2026-06-15

The first published release of SMACC — a Windows control surface for running sleep and dream studies. It includes:

Audio cues, designed in-app with the Audio Cue Designer, plus masking background noise.
Visual cues on a BlinkStick or Philips Hue light.
Biocalibrations as timed, marked tasks.
Dream reports and surveys for structured night-time data collection.
Intercom to talk, listen, and type with the participant.
EEG markers (port codes) over an LSL marker stream or a hardware TTL trigger.
The EEG Annotator for reviewing and scoring recordings (optional component).
A detailed session log, a volume safety cap, and explicit device routing so a misclick can’t blast or mislead a sleeping participant.
A per-user Windows installer (no admin rights) and a portable SMACC.exe.

Earlier 0.0.x builds predate this release and are not covered here.
