MSC R3.0 SP04 Now Deployed - The MSC has released a service pack aimed at making a number of refinements and adding some new features. The purpose of this release was to fix bundling and local/international Hazus user download issues, clarify county naming conventions for ease of use, and add features supporting a user's ability to locate the appropriate MSC products. Full county searches through the MSC are now possible via the "All Jurisdiction" option for the county being searched. The service pack also provides a submittal form to invoke Hazus download for international users and enhance the display of search results of Search by Address, Search All Products, and Subscriptions, including paginating the results to show only the first 10 products by default to improve results time. This improves overall system usability and allows public and registered MSC users to locate products in a more efficient way.

May 18, 2015 — The Hazus team has deployed Hazus 2.2 Service Pack 01 (SP01). This release contains functional updates to the Flood Model. Hazus 2.2 SP01 was deployed through the auto-update tool built into Hazus. Users need only launch Hazus while connected to the internet and accept the automated patch installation to receive SP01. The updated homogeneous state data and the new dasymetric state data are available via the MSC Hazus download webpage for free, public download. If you already created a study region using the patch with the incorrect database, you will need to create a new study region with the new database. The previous study region should be deleted and any analysis rerun in the new study region. If you upgraded your Hazus software with SP01 prior to 10AM Eastern Time on May 26th, directions for users to update an .mdb file that may lead to inaccuracies are available on the MSC Hazus download webpage, under "Download the Software."
