The update to 1.9 was just released to the downloads page, which you can find by clicking here.
This update includes the full set of changes to the Three-Year Lectionary to bring Builder 1.x to completion with readings, propers, and other materials.
Once you have installed 1.9, there is also a patch available that will update you to 1.9.1, which is a very small update intended to solve a couple of outstanding bugs still remaining in the 1.x series of Lutheran Service Builder.
A patch to 1.9.1 was also released earlier this week that should have been automatically installed on any Builder 1.8.5 installation. If you did not receive that update, please run the Check for Updates tool in Builder before attempting to download this update, as the filesize will be much smaller.
If you have any difficulties running the update, please let us know either by commenting here or by submitting a support request.
