Release Notes {#release}
=============

The release notes contain the significant changes in each PostgreSQL
release, with major features and migration issues listed at the top. The
release notes do not contain changes that affect only a few users or
changes that are internal and therefore not user-visible. For example,
the optimizer is improved in almost every release, but the improvements
are usually observed by users as simply faster queries.

A complete list of changes for each release can be obtained by viewing
the [Git](#git) logs for each release. The [`pgsql-committers` email
list](https://www.postgresql.org/list/pgsql-committers/) records all
source code changes as well. There is also a [web
interface](https://git.postgresql.org/gitweb/?p=postgresql.git;a=summary)
that shows changes to specific files.

The name appearing next to each item represents the major developer for
that item. Of course all changes involve community discussion and patch
review, so each item is truly a community effort.
