Pascal Martin has made the tenth post in his series covering PHP 7.1 and how it differs from previous versions. While this series was previously mentioned there have been significant updates to the series warranting a new post.

Here is the full list of the current ten articles he's written up so far:

• PHP 7.1: introduction and releases cycle
• PHP 7.1: testing a pre-release
• PHP 7.1: enhancements to errors handling
• PHP 7.1: changes to types
• PHP 7.0: new features from the not-so-distant past
• PHP 7.1: better syntax, a more consistent language
• PHP 7.1: create a Closure from a callable
• PHP 7.1: a few other things
• PHP 7.1: actually… No!
• PHP 7.1: the road towards PHP 7.2 and PHP 8.0
• PHP 7.1: a few bc-breaks and conclusion

There's lots of good information about this upcoming minor release in each of these articles as well as an interesting view into the release process for a new PHP version.
