+PostgreSQL 12 RC 1 Released
+===========================
+
+The PostgreSQL Global Development Group announces that the first release candidate of PostgreSQL 12 is now available for download. As a release candidate, PostgreSQL 12 RC 1 should be identical to the initial release of PostgreSQL 12, though some more fixes may be applied prior to the general availability of PostgreSQL 12.
+
+The planned date for the general availability of PostgreSQL 12 is October 3, 2019. Please see the "Release Schedule" section for more details.
+
+Upgrading to PostgreSQL 12 RC 1
+-------------------------------
+
+To upgrade to PostgreSQL 12 RC 1 from Beta 4 or an earlier version of PostgreSQL 12, you will need to use a strategy similar to upgrading between major versions of PostgreSQL (e.g. `pg_upgrade` or `pg_dump` / `pg_restore`). For more information, please visit the documentation section on upgrading:
+
+https://www.postgresql.org/docs/12/static/upgrading.html
+
+Changes Since 12 Beta 4
+-----------------------
+
+There have been many bug fixes for PostgreSQL 12 reported during the Beta 4 period and applied to this release candidate. These include:
+
+* Add additional "leakproof" markings to certain string functions to better support nondeterministic collations. This can positively impact the performance of some query plans
+* Removal of the ECPG `DECLARE STATEMENT` functionality
+* The ecpglib major version change was reverted
+* Fix handling of nondeterministic collations with pattern_ops opclasses
+
+For a detailed list of fixes, please visit the open items page:
+
+https://wiki.postgresql.org/wiki/PostgreSQL_12_Open_Items#resolved_before_12rc1
+
+Release Schedule
+----------------
+
+This is the first release candidate for PostgreSQL 12. Unless an issue is discovered that warrants a delay or to produce an additional release candidate, PostgreSQL 12 should be made generally available on October 3, 2019.
