I see from the changelog that some changes have been done to Image Sequence to allow drag-and-drop.
These changes has caused the use of Image Sequence in macros to be severely broken since 1.53d.
See the below demo macro to reproduce the problem.
I am trying this with daily build 1.53e with Java 8 on Windows 10/64 but the problem is also present in 1.53d.
It seems that the problem is simply that the previously available options were removed from the new dialog.
But instead of warning the user that the functionality was removed, it is just silently ignored, giving the wrong results.
So, can the previously available options be migrated to the new dialog?
Or can the new dialog be renamed to something else, restoring the old one, so that existing macros will work?
My workflow completely depends on the ability to open virtual stacks with specified slice spacing as I work with very large stacks (16GB to 64GB) so always needing to open all slices in memory is not an alternative, especially not over a slow network or when working on a computer with less than 128GB of RAM.

//load generated folders as image stacks using some of the available options
//open 25 slices at 50% size:
run("Image Sequence...", "open=&path1 starting=5 increment=5 scale=50 sort");
//1.53c and before: options works as expected
//1.53d and after: options are silently ignored giving the wrong results
//open 12 slices virtual:
run("Image Sequence...", "open=&path2 increment=3 sort use");
//1.53c and before: options works as expected
//1.53d and after: options are silently ignored giving the wrong results
//re-open path1
run("Image Sequence...", "open=&path1 file=.tif sort use");
//1.53c and before: path1 (t1-head) was opened as requested
//1.53d and after: path2 (t1-rendering) was silently opened instead of path1; I don't understand why
//trying a wrong path
path3 = "X:/some/non/existant/path/";
run("Image Sequence...", "open=&path3 file=.tif sort use");
//1.53c and before: macro exits with an error message
//1.53d and after: t1-rendering was silently opened instead of giving an error message
