Version 5.57 includes some changes in how the Donor Manager keeps the Donor ID number.  In the past, the ID number has been "padded" with leading zeros.  While this has generally worked out well, for some giving files it has caused some problems, leading to having to "match" contributions to partners each month.  Hopefully the changes in this version will improve the matching.
It is possible that you may have to "match" to donors again this month due to this new method, but in future months, it should work as expected.

In addition, beta support for US Center for World Mission giving files (tntMPD format) are included in this update, as well as Missionary Ventures.   Feedback is invited.

Plus, there are a few updates in the WBT gift importer, and the CCCU gift importer.
