Sitecore 10.4.1 is out. At first it looks like a small update, but there are several things that can impact your setup as a developer. Especially if you’re working with containers, Solr, Identity Server or Azure monitoring. Here’s a quick overview of the most important changes and a few thoughts from my own point of view.
Solr 9.8.1 is now required
This update switches to Solr 9.8.1. The older 8.11.2 version is no longer supported, so you will need to upgrade. With the new Solr version you get a big leap in Security and performance fixes from the older version. I would say that’s the most important parts. Just modernising your Solr foundation.
If you’re using Sitecore containers, you also need to use the new container deployment package that matches the new Solr version. The older container images will stop getting OS patches, so best to move forward.
Identity Server now uses .NET 8
The Identity Server in Sitecore is now version 8.0.16 and built on .NET 8. That’s a good step forward, but it does come with two changes you need to handle:
- Encrypted SQL connections are required now.
- You have to run a database upgrade script.
So if you’re automating your deployments or have custom Identity Server config, be ready to update both connection strings and database setup.
Azure Application Insights changes
If you’re using Application Insights for monitoring, the old Instrumentation Key is no longer supported. You have to use a connection string instead. This is a Microsoft change and Sitecore follows it now. There are updated ARM templates included if you use Azure to set it up.
Lots of resolved issues from previous version
Sitecore 10.4.1 brings some important backend changes. For most environments, it’s worth upgrading to keep things supported and future proof, just make sure to test and read the updated install instructions carefully.
