At the first company we released a few times a year. You have to remember that CI/CD wasn't a thing back then. While I worked on a web-based product at this company, it was a time when it was still very common to release software on physical media like CD's.

At the second company we integrated Agile so we released every two or weeks (I can't recall which). The first time I heard about CI/CD was at this company from co-workers who came back from a conference all excited about it.

That's my question as well. Bug free code is not the goal. Valuable product is.
