Apple just launched macOS Monterey 12.1, iOS 15.2, and iPadOS 15.2 beta 3 versions for developers. In these beta versions the company basically adds bug fixes, stability improvements and solutions to some problems detected in the previous beta versions.
The new beta versions can now be downloaded directly from the web for developers and in the case of the iOS and iPadOS versions, they can be downloaded via OTA from the devices themselves.
For now, the times between beta versions are correct and it seems that we are on a good pace to have a final version before the end of this year, they may wait until early next year. Be that as it may, we imagine that they will want to leave everything in condition for the Christmas period so We do not expect too many changes to the system that compromise its security or stability.
No changes are added beyond the bug fixes that we know of, if news appears in this beta 3 version we will publish it on the web. As always, we recommend staying away from the beta versions of macOS for developers and waiting at most for the public beta versions that will be available soon. Anyway the best in all cases or it is best not to install these beta versions to avoid possible problems or incompatibility with any App or tool that we need in our day to day.
