This paper examines historical releases of Sendmail, Postfix, Apache httpd and OpenSSL by using stat

This paper looks at old versions of Sendmail, Postfix, Apache httpd, and OpenSSL by checking how often they were released. It’s like looking at how many times your favorite video game gets updated to fix bugs or add new features. For example, if you have a toy that keeps breaking and your parents keep fixing it, that’s kind of like how these software programs have updates to make them work better. One verifiable fact is that Sendmail, one of the programs mentioned, has been around since 1983 and has had many updates over the years to improve its performance and security.
