Manual Updates for InDesign 2015.0

I have an Enterprise license for Adobe Creative Cloud.  I have a vendor that requires use to use InDesign 2015.2, as their plugins only work well with that version.  I've been searching for updates to install manually, as the Creative Cloud Packager offers version 2015.0 or 2015.4, only.  I found Adobe's Product updates page, but it only goes up to InDesign CC 2014.  Does anyone know where on the Adobe site I would find updates to manually install?
