This morning I posted beta-4 of wp-SwimTeam v1.40.  This beta update addresses a number of issues mentioned recently on the WordPress Support Forum.

1. Support for Age Groups where min and max age are identical.
2. Mapping zero (0) as upper and lower max age in event files to min and max age in wp-SwimTeam.

There are a few other fixes as well plus some debug code cleanup.  I still have a couple of things to clean up before releasing v1.40.  Also in this build as are the basic building blocks for Roles and Capabilities.  If you use a Roles and Capabilities plugin, you may see some new swim team related data which has been defined but is not yet being used.
