  • (E/P) Stitcher wizard:
    • Fix issue where deconvolution templates did not get loaded for Ch > 0.
  • (E/P): Image Stabilizer:
    • Fix potential memory leak.
  • (E/P): Cropper:
    • Prevent the use of an unsupported combination of using strides and operating on a binary source image in creating the MIP for visualization.
  • (E/P) Preferences window:
    • Scale with DPI value.
  • (E/P): SPIM labels:
