and --readers options in bulk import configuration files
* insight: new options for skipping various import steps to speed up
the process (match cli’s --skip option)

lightweight UI
* insight: new loading placeholder when browsing data to show when an
image is busy being processed and not ready to generate a thumbnail
* insight: added error placeholder when browsing data to indicate a
failed import
* server: preventing recalculation of checksums for upload
* server: providing better performance logging, accessible to users
via fs logfile
* as well as preservation of Bio-Formats’ knowledge of channel colors
where provided.

Other client changes include:
