I have a simple question about Github. If I make a new "Release" (with a tag) with some binaries and source code in a "private" repository, will this Release stay private too (hidden from the public)? or once published, anyone can see the Release/tag regardless of whether the repository is marked as public or private? I couldn't find information about this in the documentation.
If your repo is private, only people who have read access to it will be able to see the releases. The public won't.
From documentation:
Anyone with read access to a repository can view and compare releases, but only people with write permissions to a repository can manage releases.
