Apple today seeded the second beta of an upcoming iOS 10.2.1 update to public beta testers for testing purposes, one week after releasing the first iOS 10.2.1 public beta and one day after providing the second beta to developers.

Beta testers who have signed up for Apple's beta testing program will receive the new iOS 10.2.1 beta update over-the-air after installing the proper certificate on their iOS device.

Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to both iOS and macOS Sierra betas. Betas are not stable and include many bugs, so they should be installed on a secondary device.

ios-10-2-1-beta
It isn't known what features are included in iOS 10.2.1, but as a minor 10.2.x update, it appears to focus on bug fixes and performance improvements rather than major outward-facing changes.

No new features were discovered in the first two developer iOS 10.2.1 betas, and we likely won't know the full extent of the changes until the update is released with full release notes.

Are some people here just so petty that they feel obligated to complain about anything including how Apple's software engineers are actively working to squish bugs (and introduce openings for new ones)? Before you answer, keep in mind this is rhetorical
You do appear to be offering a penny for our thoughts though! ;-)

I don't mind them either.

Some detailed release notes would be nice though. It's mildly frustrating installing them without knowing what's in them.

I wish the Apple apps like Pages and Numbers and Photos got weekly updates as well.
