+-  update to 1.53u:
+  * the Image>Transform>Bin command now supports z-binning of 4D
+    hyperstacks.
+  * the Analyze>Plot Profile command works with rotated rectangles.
+  * The Edit>Selection>Line to Area command converts straight line
+    selections to rotated rectangle selections.
+  * improved recording of the Edit>Selection>Properties command and
+    added a comment to the Edit>Options>Line Width dialog to make
+    it clearer what the command does.
+  * the Selection Brush Tool is no longer disabled when activating a
+    selection in an overlay by double clicking on it.
+  * made GenericDialog.resetCounters() public so it can be called by
+    plugins using GenericDialog.addButton() (example).
+  * added the recordable Image.removeScale() macro function and the
+    ImagePlus.removeScale() method.
+  * Added the ImageProcessor.setColor(String) method.
+  * fixed a bug that caused toolbar contextual menus to ignore the
+    Edit>Options>Appearance "GUI scale" setting.
+  * fixed a bug that caused the "Results" menu in a table to 
+    disappear if the table was renamed.
+  * fixed a bug that caused the File>Import>TIFF Virtual Stack
+    command to not correctly calibrate TIFF stacks that were not
+    created by ImageJ.
+  * fixed a bug that caused the Image>Overlay>From ROI Manager menu
+    command to not transfer the ROI positions.
+  * fixed a bug that caused the Edit>Selection>Straighten command
+    to change the global line selection width.
+  * fixed a bug that caused ROIs with x or y coordinates greater than
+    60,535 and less than 65,535 to be saved incorrectly.
+  * fixed a bug that caused ImageJ to create TIFF files with invalid
+    RowsPerStrip tags when the image height was greater than 65,535.
+  * fixed several bugs with Image>Stacks>Plot Z-axis Profile "Live"
+    plots.
+  * fixed a bug that caused the "CP" window to not be updated when
+    the Color Picker tool was used to pick new colors from the active
+    image.
+  * fixed a bug that caused the Opener.openAndAddToRecent() method to
+    return 'false' when the file was opened successfully.
+  * worked around a Java bug on Windows that caused the main menu bar
+    sub-menus to not scale to larger than 17 points. Unfortunately,
+    the main menu bar font size on Windows is still limited to 17
+    points regardless of the "GUI scale" setting.
+  * fixed a bug that caused the Roi.Paste macro function to not work
+    as expected.
+  * fixed a scale bar width rounding error.
+  * fixed a bug that caused the Edit>Selection>Rotate command to
+    convert Rotated Rectangle selections to Polygon selections.
+  * fixed bugs that caused the Scale and Rotate commands in the ROI
+    Manager to only work correctly when processing all the ROIs.
+  * fixed a 1.53t regression that caused the Image>Stacks>Z Project
+    command to ignore the last slice when doing "Average" projection
+    of 32-bit stacks.
+  * fixed a 1.53o regression that caused unexpected error messages
+    when double clicking on a line in a table or in the ROI Manager
+    when a custom action was not defined (example).
