            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.

              Release Notes: Support was added for wildcard and multiple coverfile names on the command-line. This enables embedding of a message into coverfiles in bulk. A minor bug was fixed.

                    Release Notes: Support for using a randomly generated image as a cover file using the '-random' option was added. A command line option was added to list the supported read/write image formats. JAI can be installed to provide support for additional image formats. A bug where channgelBitsUsed was written wrongly in the header data was fixed. A check was added for the extension for Output Image File selection. Header versioning support was added for a compatibility check in future versions.
