I am a bit confused; whether I am using Rails 5.1.4 or upgrading to 5.2.0.rc1 (Ruby version is 2.5.0) a lot of new files have all of a sudden appeared in my apps and I am unsure of the impact they have on my application.
First of all there are hundreds of strange files created in subfolders under temp/cache/bootsnap-compile-cache. They all appear to just contain strange characters and I don't really understand the purpose of the files being created or why they all of a sudden appears after 1 year creating many apps.
log/development.log, tmp/cache/, tmp/restart.txt are all new files/folders appearing all of a sudden. Can someone please explain what the reason for this might be?
