Read the Development Updates every week, and accept your OTA updates when they arrive approximately every month.
To ask about your actual situation (if there is any reason for it to be unusual) you would need to define the version more fully [HOWTO] Give complete /e/OS version info easily for support, answers, comparison etc – as lots of people are asking about OTA Upgrades, which only happen for devices running a stable build. I think maybe you do have stable ?
If you miss a simple update, it is fine to jump a build, every update is a full ROM, they are not incremental.
