This update fixes a few crashes and greatly improves compatibility with legacy plugins. This compatibility is being accomplished by hot-patching the code (IL) in the DLLs, and it can be CPU and disk intensive the first time the app is launched after updating. After that, the hot-patched DLLs are cached and will load much faster (until the first launch after the next app update).   There is still ongoing work to make sure as many legacy plugins as possible can be made to work.
