It is official now, Microsoft ended its mainstream support to AX 2009 as of 10th of October 2018. First launched in 2008, this marks an end of an era!
Microsoft Dynamics AX 2012 R1 and R2 also reach the end of support but R3 continues. Ending mainstream support for a Microsoft’s product means no more product enhancements or security updates, hotfixes or feature requests.
