From 42c84ea6d88ecb94c2a7d2e3e94e86522cbd19aa Mon Sep 17 00:00:00 2001 From: K Sai Kiran Date: Thu, 25 Jun 2020 14:45:50 +0530 Subject: [PATCH] Feature 8840 Notify without auth and typo fixes Initial implementation always needed auth to make notification. After going through sol005, understanding is auth can be optional and while subscribing auth is kept optional. Also fixed some typos.
