CWMS Release Notes

This area is to help with upgrading CWMS version from the previous version (i.e. if the version denotes 3.2.1, it is providing information from CWMS 3.1.1 to CWMS 3.2.1).  If you jumping more than one version, you will need to look at multiple versions in this space (i.e., if going from CWMS 3.1.1 to CWMS 3.2.2, you should look at the 3.2.1 version and then the 3.2.2 version).

Please note the availability of a patch version CWMS-v3.2.3.1, which addresses a pair of CWMSVue issues.

CWMS Server & Database Software

The CWMS Server and Database Software and their configurations are usually the responsibility of your CWMS Administrator and the notes provided in the following link were prepared for them.  However, all CWMS users should have an understanding of what software is running on your servers so it always good to learn about what your CWMS Admins are dealing with. 

Administrators, please review the various notes described in CWMS Server & Database Software Information.

Scripting

Custom Python and Jython scripts are used by most offices on both the server and client platforms to perform a variety of necessary, often repetitive, and sometimes unique tasks.  Please review the various notes provided in Scripting to learn more.
