• Add PositionFormatExecutor.

• Fix issues with FileAcquisition.

• Add sample to marker-associated callbacks.

Migration Guide

Name Changes

• Stack has replaced Cube in class names. For example, CubeTensorEndpointX is now StackTensorEndpointX. Similarly, CubeFormatExecutor is now StackFormatExecutor.

IO Leading

IO delays (e.g., for galvo response) are no longer handled in post-processing via the formatter. Instead, the engine now generates leading IO signals that cancel out the IO delay. The delay in samples is passed via .add_io() in the engine config. Multiple IO delays are possible. Change fc.stream_delay_samples = round(cfg.galvo_delay * ioc_out.samples_per_second) to ec.add_io(io_out, lead_samples=round(cfg.galvo_delay * ioc_out.samples_per_second)).
