This release is nearly identical to v0.9.14 but with a tiny yet critical fix. (You are strongly encouraged to read those release notes instead because they are much more interesting and relevant to you as a user!)
Unfortunately, v0.9.14 hit a very niche issue where the compiler building the code hooked it up to a JDK16 API despite the build scripts set up to target JDK11. You can see this YouTrack issue for more details.
For this release, we actually changed the code to a functionally identical algorithm that avoids using the problematic API, but we also introduced a new process where we have the GitHub CI build the artifacts rather than build them locally. This ensures a sterile, consistent environment for builds where the only JDK available there is JDK11.
