If your work does not involve these two CWMSVue issues then feel free to stick with the original release version of CWMS 3.2.3. There are no other differences.
There are no changes to servers or database associated with CWMS 3.2.3.1.
Improvements from CWMS 3.2.2
There have been no impacting changes between CWMS 3.2.3's CWMSVue compared to CWMS 3.2.2's version, although many bugs were fixed.
Note that CWMSVue 3.2.3 resolves several problems that caused disconnections from the CWMS database. If you had previously implemented the "keep alive" feature in your "personal config" files, HEC recommends commenting out the override for "keep alive" and trying CWMS 3.2.3 under the default setting.
