A new release of the most advanced open source database is now available!
As always, as a new major release, there are great gobs of little features that have been added, most of which, individually, likely don’t matter to any particular individual. (For instance, there are a couple dozen enhancements to ECPG, and if you don’t know you’re using that, you almost certainly aren’t, and so those changes likely don’t affect you.)
But there are plenty that are liable to matter, and, indeed, to help improve behaviour of one’s streams of queries, often without even needing any changes to applications.
See also the official release notice, for “markety-speak.”
And see official release notes (that are part of the documentation tree) for deeper details of all the changes in the new release.
