The Flash Center is making available bug fixes to FLASH 4.0 in two forms: (1) as an update tar file, and (2) as a diff file for the "patch" command. The differences from FLASH 4.0 are limited strictly to bug fixes. No new features have been added, and documentation is unchanged. The release string (in file RELEASE) is updated to "4.0.1_release" to help users identify their code version. (1) To get the updated tar file: * Go to the Flash Code Web page at http://flash.uchicago.edu/site/flashcode/ and use the 'Code Request' and 'Download' links. Or go to http://flash.uchicago.edu/coderequest (if you have not yet signed a license agreement) or to http://flash.uchicago.edu/download directly. You are required to have signed the License Agreement before downloading the code. Select FLASH4.0.1 from the list of available downloads. (2) To apply the patch file: * Download file FLASH4_0-to-4_0_1.diff from http://flash.uchicago.edu/site/flashcode/user_support/FLASH4_0-to-4_0_1.diff . A License Agreement or password is not required. * Change to the top level directory (i.e., the directory containing the source, sites, tools, etc. subdirectories) of your existing FLASH 4.0 directory tree. * Run patch -p0 --dry-run < FLASH4_0-to-4_0_1.diff to verify that the patch can be applied cleanly. If you get error messages, you probably are in the wrong directory, or your FLASH version is not 4.0, or you have made local changes that interfere with the patch. If it is not possible to fix the problem, revert to getting the tar file as per (1). * Run patch -p0 < FLASH4_0-to-4_0_1.diff to update FLASH 4.0 to FLASH 4.0.1.
