The OP works in the Software field and the one thing customers hate the most is the Removal of Good Functionality that they have built a Business process around. We constantly have to add New Functionality due to ever changing Pharma Regulations and sometimes features and functionality changes, not always for the better.
Obviously this is not a business to build a process around, but people who have been here for many years are used to things working a certain way. When the software gets upgraded, people expect new functionality as well as better working older functionality, not a complete change to how almost everything worked previously.
So all the OP was asking for is to see the same New Posts as he has been used to seeing for the last umpteen years. In today's Software writing, that query does not seem too difficult, certainly not if it was already working the code already exists.
The OP also tried navigating several other threads to find this tiny question in between a bunch of crying and whining responses. He gave up.
