+### Support Overlapping Start and End Markers for Custom Folding Regions

+
+Custom Folding Regions have been enhanced to allow using the same text for both the start and end region comment.
+If the start and end region markers are the same, the same comment can be used to end a folding region and start a new one.
+The last section automatically ends when the last block is closed or at the end of the file.
+
+This is useful if a class (or other Java file) contains multiple sections that are seperated with some comment.
+To use this functionality, check "Enable folding of custom regions" in `Window > Preferences > Java > Editor > Folding` and enter the same text in "Region start comment text" and "Region end comment text".
+

+
+This marker can then be used in comments to separate start and end regions.
