The PostgreSQL Global Development Group announces today that the first
beta release of PostgreSQL 9.5 is available for download. This release
should contain all features and APIs which will be in the final
release with few, if any, changes. Users should begin testing their
applications against 9.5 Beta 1 in preparation for the final release.
Changes Since Alpha2
--------------------
Many bugs and issues reported by our users and contributors have been
fixed since the release of Alpha2. These include:
* significant adjustments to Row Level Security (RLS) semantics
* deadlock with LWLock improvements
* index corruption issue with BRIN indexes
* couldn't connect using PGSSLMODE=require on Windows
* various problems with commit timestamp tracking
* hash join memory leak
* inconsistent behavior of jsonb_set with array append
In particular, the semantics of Row Level Security have been changed
to be consistent with the existing PostgreSQL GRANT-based permissions
system. As an example, RLS now applies both the INSERT policies and
the SELECT policies when INSERT with RETURNING is used. Users should
test the RLS application of RLS policies and re-test any existing RLS
configuration to ensure that there are no regressions for their
use-cases. For more information, see the documentation on Create
Policy (http://www.postgresql.org/docs/9.5/static/sql-createpolicy.html)
and RLS (http://www.postgresql.org/docs/9.5/static/ddl-rowsecurity.html).
If you reported an issue while testing PostgreSQL 9.5, please download
Beta1 and test whether that issue has been fixed. If you have not yet
tested version 9.5, now is the time for you to help out PostgreSQL
development. Known issues which are still open are listed on the Open
Items page.
Beta Schedule
--------------
This is first beta release of version 9.5, indicating that very few
user-visible feature changes are expected before final release. The
PostgreSQL Project will release additional betas as required for
testing, followed by one or more release candidates, until the final
release in late 2015. For more information, and suggestions on how to
test the betas, see the Beta Testing page.
Full documentation and release notes of the new version is available
online and also installs with PostgreSQL. Also see the What's New
page for details on some features.
