17.3.0

Upgrade Notes

In 17.3 we have upgraded our dependency on MailKit to 4.15.1. This is a minor version update, but we found a few changes we had to make in core to accommodate changes to nullability constraints. Unless using methods of this library, or it's transitive dependency MimeKit, it's unlikely projects will be affected. The update is necessary though, as the version we previously depended on now has a security vulnerability raised against it.

We have made a change to how we handle redirects which brings a significant performance improvement for publish time on large sites, when documents with many descendent nodes are published. If you have custom URL providers you should review this change, as there are some very rare cases where you'll need to adjust to ensure descendent redirects are correctly handled.

Note also that we now auto-generate HMAC secret key for new installs. This has been applied to make Umbraco more secure by default, but it's not been forced for upgrades.
