Breaking changes
Propagation now stops after 8 consecutive empty slices in each direction. Pass stop_after_empty=None to track through the whole volume, as 0.2.8 and upstream MedSAM2 do.
Fixes
A symlink in the output folder can no longer redirect where a run writes. Outputs are staged in a private folder and moved into place.
New
medmlx now checks that medsam2 fits in available memory before running it. The runtime declares a 1.3 GB peak, and the README lists the 156 MB weight download and the measured peak.
Faster
Volume propagation is faster and holds less on the host, with bit-identical masks. The next frame is prepared and encoded while the current one is tracked, and completed masks are streamed into the output volume.
