which Extension Library IBM support for Lotus Notes 853? currently we use the extLib version: 8.5.3.20111208-0717, which we install over the 8.5.3 Upgrade Pack 1. But I miss in this version the restservice xe:customrestservice e.g.
So my question is, can I download every extlib version for 8.5.3 from openntf and install that, without lost my ibm support?
