In the VMware Product Interoperability Matrices is shows that VMware tools 10.3.0 is compatible with ESXi 5.5u3
But VMware Tools 10.3.0 is deprecated, however it says to use 10.3.2 or higher. I was able to find version 10.3.5.
Is this compatible with ESXI 5.5u3 or should I use 10.2.5 ?
I have the same question. Going through the release notes, I can only find that 10.3.2 says it supports 5.5 and later:
10.3.2 was also released around September 2018, the same time vSphere 5.5 Update 3k was released.
