Since the last version release of HotPatcher over half a year ago, its support for UE4 has been commendable, but its support for UE5 has been lacking. There have been frequent inquiries in the group about adaptation.
The last Release version of HotPatcher was v81.0, released on 20230604, which only supports UE5.1.0 and does not support WP and Nanite. Subsequently, Epic released UE5.2 and 5.3, but the plugin has not been adapted. Although one can modify compilation errors themselves, functionality support in UE5 is somewhat in a beta state.
Taking advantage of the Qingming holiday, I worked intensively for a few days to comprehensively optimize and adapt HotPatcher to be compatible with the latest versions of UE4.21 to UE5. A new Release version has been published: v82.0. The latter part of this article will discuss the adaptation of HotPatcher in UE5, precautions, and the update log.
Additionally, in 2020, I wrote an article: Some Thoughts and Ideas on Open Source, and over the past two years, I’ve had some new thoughts on maintaining open source projects. Let’s summarize together.
