It will be very good for me if these changes will be added to rqueue v3

Could you pull the latest changes from remote and check if the CI is passing after that?

Done

[igorjava2025]

check if the CI is passing after that

The check did not start after push changes. What I need to do to start check? Or does the absence of the check red signal mean that the check has passed?

I plan to use the rqueue library with Spring Boot 3.maxMajorVersion.maxMinorVersion. I used Spring Boot 3.5.7 in rqueue load test project. Also I will use rqueue with spring boot 4.maxMajorVersion.maxMinorVersion version in the future.
