Release 1.2.0
We've got 3 significant enhancements in the 1.2.0 release (internal). After much preparation, we've added the address change report (aka address lineage).  This feature allows you to discover, for any given address, what address(es) preceded it and/or what address(es) succeeded it.  This works at the parcel level and is a many to many relationship.  To see the change report for an address, just click on the link/unlink dates within the address detail report.  Most addresses will not have any lineage yet because we started capturing lineage on February 15, 2012 when EAS was first released.  The second enhancement in this release is a major rework of the address detail report.  We mostly did this to support navigation to the address change report.  We also moved it from a popup on the map to the left hand panel because most people thought the popup was blocking too much of their view of the map.  Finally, address validations are now visible by default.  You can spot an address that has a validation issue by looking for the little yellow warning triangles () on the map and in the address detail report.  What is a validation issue?  For example, a typo may result in "1000 Main Street" being created on the 100 block of Main Street.  Another example is when an address remains linked to a parcel even though the parcel has been retired.  EAS won't force you to fix all address validation issues - but now you'll see the warnings right up front - and you decide if something needs fixing.  We expect that there will be a few more features around validations in the medium term. The complete list of issues and enhancements in this release is here.
