Release Notes: Adds support for embedding digital (invisible) watermarks in images that can be verified later.
Release Notes: This release fixes a major bug where the extract action was not working for the RandomLSB plugin.
Release Notes: This release removes the "Auto-Select" option for the Extract algorithm. It has an exception check in case of an out of memory error.
Release Notes: Support for bulk embedding of messages was added. Multiple files can now be selected or a wildcard can be provided for cover files.
Release Notes: This release adds minor bugfixes and support for the new algorithm RandomLSB. RandomLSB uses the Least Significant Bits of image pixels in a pseudo-random manner, so it becomes very difficult to detect the stegged data using statistical methods. This method is slower than regular LSB, but it is more secure.
