I just updated to macOS Sierra 10.12.1 (from OS X Yosemite) but now note that double click will select all text on the line.

Posted on September 21st, 2016 by Jay Vrijenhoek. This week Apple released macOS Sierra to the public and, apart from some nice new features, it includes fixes for 65 security vulnerabilities and some tweaks to the operating system itself to improve security as well.
Just a few days after all of Apple's major platforms were updated publicly, developers have been supplied with new beta releases of point-one updates, including iOS 10.1 and watchOS 3.1.A total of five new betas are available to registered developers as of Wednesday. They are:

- macOS Sierra 10.12.1 beta (build 16B2327e)
- iOS 10.1 beta (build 14B55c)
- watchOS 3.1 beta (build 14S452)
- tvOS 10.0.1 beta (build 14U54)
- Xcode 8.1 beta (build 8T29o)
Registered devices can be updated over the air via Software Update. iTunes can also be used to manually update iPhones, iPads and Apple TVs.
Currently, Apple is relatively tight lipped about what changes the new software might include. For example, a point-one version for iOS would suggest new features will be included, however the release notes simply mention that developers will have access to barometric pressure data on new iPad models.
Release notes for watchOS 3.1 also list known issues with the pre-release software, but do not disclose any new features. The point-zero-one update for tvOS, meanwhile, suggests it will simply squash bugs and will not boast any new features.
Members of Apple's public beta program are likely to receive similar beta builds of macOS Sierra 10.12.1 and iOS 10.1 in the coming days. watchOS, tvOS and Xcode are not included in Apple's public betas.
