Quite a few Patch Set Updates were released for the EPM products in December. The latest ones for HFM and Planning 18.104.22.168 (both PSU 306) are probably the biggest updates and include lots of fixes for both products. HFM for example has received further improvements to web data form performance and two handy utilities - HFM Application Backup Utility and HFM Index Update Utility - have made a comeback. Have a look at the readme files for more details and the prerequisites!
