UPDATE LOG:
8/18/08
Incremental improvement ot accuracy.

8/5/08 Launch v6.4.  

Added hashing option for Blocking and Deterministic Evaluation steps for users
running SAS v9.2.  Depending on a variety of factors, the hashing algorithm may
reduce blocking time.

User can specify multiple datasets from which The Link King will extract records for
linked individuals and attach the Link King generated uniqueid to extracted records.

SAS v8 no longer specifically supported in v6.4.  New modifications may not be
compatible.

Note: With the release of SAS 9.2, SAS has created yet another warning message
which – in the context of this application – can be ignored.  Specifically, the message:

    WARNING: Multiple lengths were specified for the variable {var name}
    by input data set(s). This may cause truncation of data.

will appear whenever The Link King truncates the length of a data field to be no longer
than the longest value in the field.

6/13/08
Efficiency improvement in implementation of the Jaro-Winkler algorithm.

5/30/08
Incremental improvement to accuracy and efficiency.

2/29/08
Fixed bug. New Jaro-Winkler algorithm (added 2/12/08) would crash when no middle
name was present (or MI only).

2/12/08
Resource utilization efficiency enhancement when blocking level set to "High".

Integrated Jaro-Winkler string comparison algorithm (with prefix and long-string
adjustments) into the algorithm.

11/13/07
Display enhancement

10/19/07
Fixed minor bug in display of pending consolidations.  Misc. incremental improvements
to processing.

10/17/07
Added control to allow user to generate listing of unmatched records from the
SAMPLE dataset.

10/10/07
A number of incremental enhancements.  Primarily focused on the interface and
processes associated with the "Estimate PPV" feature and other aspects of the Manual
Review interface.

10/1/07
Dates (formatted as MM/DD/YYYY string) can now be used as a "flex" variable. A
comparison protocol similar to that used to compare birthdates is used to evaluate the
similarity of "flex" dates for record-pairs.
