The following enhancements were made to MGI between the release of version 1.3.6 and the latest release of version 1.4. Important functionality changes that may affect current users of MGI are highlighted at the beginning of the list. Other enhancements are grouped by the MGI tag where they appear. The most recent enhancements for each tag are listed first.

New MGI Tags

mgiConditional - The mgiConditional tag is an improved conditional comparison with extended comparison relationships and a simplified tag structure.
mgiCreditCard - The mgiCreditCard tag interacts with MacAuthorize Hub to provide real-time credit card processing through MGI.
mgiFileDelete - The mgiFileDelete tag deletes a file on the server.
mgiLoop - The mgiLoop tag repeats actions for a specified number of iterations or for a specified list of values.
mgiPGP - The mgiPGP tag encrypts any email including customer orders with a passphrase file.
mgiRotate - The mgiRotate tag rotates the display of text files, images or database values.

Functionality Changes

Database Search Results - We discovered that searches could unintentionally return a table of information so large that it crashed WebStar trying to build the page. To avoid such situations, a default search result limit of 25 was added to all database searches. If an existing database search may return more than 25 results, you must include the "mgiPreviousButton" and "mgiNextButton" variables in the results format file in order for the additional results to display or you can customize the number of results using the "mgiResultsLimitPopup" variable in the search format file. In a database search using the administrative functions of mgiEditDatabase, search results are limited to 250. Administrative database searches should be narrowed to remain below this limit.
 
Infinite Loops - We discovered that an infinite loop could occur if a format or template file was called by a tag within the format or template file. Protection against infinite loops was added to tags that use format and template files including mgiPoll, mgiShoppingBasket, mgiConfirmOrder, mgiQuiz and mgiSearchDatabase. The mgiFileInclude tag also had the potential for causing infinite loops when the included file contained an mgiFileInclude tag that referred to the included file. Protection against infinite loops was also added to mgiFileInclude.
