How often are releases made?

Release frequency depended on the project and the methodologies used.

In projects with Agile (Scrum), weekly or bi-weekly releases were practiced. This required a high level of test automation and well-established CI/CD processes.

In larger and more conservative projects, releases could be monthly or even quarterly. In such cases, testing cycles were longer and included full-scale regression testing.

There were also projects with continuous delivery, where releases could happen several times a day. Here, a high level of automation, monitoring, and canary / blue-green deployments played a key role.
