The following issue just crept up on me. The steps mentioned below had worked just fine until about 2 days ago.

When I deploy a update to a solution (of web parts) to a SharePoint 2010 server I don't see the update. The solution does get installed, but from what I can tell the installed web parts are over a month old (nothing new is installed).

I do the following steps through PowerShell:

retract the solution from the web app
remove the solution  
add the solution  
install the solution to the web app

I have tried restarting the Web App, restarting IIS and also restarting the server. Nothing seems to work.

I notice that after I remove the solution it does get removed from the GAC. After I add/install it the solution does reappears in the GAC.

Am I missing something? Am I overlooking a step that I should be doing? Something to try?
