Yeah, there are plenty of releases where nothing gets removed, but files do
get removed from time to time, so simply extracting the zip on top of the
old directory will cause problems at least occasionally. Also, in the case
of Linux, an .so is generated with a specific version number in it, so every
release has different files. I don't think that Windows currently has
anything like that, but it could in the future. So, if you want to use the
zip, then you should always remove the old version and not simply overwrite
it.
