There are two new versions of LDSql available on the downloads page:
http://www.ldsql.com/home/downloads
The v 0.9.13 release supports MLS version 3.3.0 and later, which
dropped the MRN (Member Record Number) from the Membership.csv file.
LDSql itself is not forwards- or backwards-compatible with different
versions of MLS exports. However, some implementers do maintain such
compatibility in their loading processes. These implementers are best
advised to use v 0.9.12 of LDSql, which did support the MRN column
directly. The MRN column in the final LDSql database in v 0.9.13 is
empty and deprecated, but still present to minimize damage to
implementers' own programs.
Both versions include new support for Spanish-language MLS exports, a
tweak to cope with a bug in MLS export file Organization.csv, and some
loading optimization.
