Upgrade 13.4.1 to 13.4.2
Remove Login Page Captcha Configuration
As of Bloomreach Experience Manager 13.4.2, the captcha has been removed from the login page. Therefore, if your implementation project configured any of the following two configuration properties at the node /hippo:configuration/hippo:frontend/login/login/loginPage, they should be removed to prevent errors being logged during bootstrap after upgrading to 13.4.2.
Update Customized Login Page
If your implementation project contains any login page customizations, those may need to be updated when upgrading to 13.4.2.
As of Bloomreach Experience Manager 13.4.2, the SimpleLoginPlugin has been removed. The DefaultLoginPlugin, which extended SimpleLoginPlugin prior to 13.4.2, now extends LoginPlugin directly. If your implementation project extended SimpleLoginPlugin, it should be updated to extend DefaultPlugin instead.
(Optional) Use Relevance without Elasticsearch
As of Bloomreach Experience Manager 13.4.2, it is possible to use Relevance without Elasticsearch, at the expense of the Experiments and Trends features.
Customers upgrading implementation projects from 13.4.1 to 13.4.2 who don't use Experiments and Trends and/or no longer want to use Elasticsearch can choose to remove the Elasticsearch requirement (and Experiments and Trends functionality) as part of the upgrade process.
All other customers can skip this step.
