Hi, Attached is a draft of the PostgreSQL 13 RC 1 release announcement.
If you have feedback, please be sure you've left it no later than 2020-09-16 AoE. Thanks! Jonathan
PostgreSQL 13 RC 1 Released =========================== The PostgreSQL Global Development Group announces that the first release candidate of PostgreSQL 13 is now available for download. As a release candidate, PostgreSQL 13 RC 1 will be mostly identical to the initial release of PostgreSQL 13, though some more fixes may be applied prior to the general availability of PostgreSQL 13. The planned date for the general availability of PostgreSQL 13 is September 24, 2020. Please see the "Release Schedule" section for more details. Upgrading to PostgreSQL 13 RC 1 ------------------------------- To upgrade to PostgreSQL 13 RC 1 from Beta 3 or an earlier version of PostgreSQL 13, 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/13/static/upgrading.html). Changes Since 13 Beta 3 ----------------------- There have been many bug fixes for PostgreSQL 13 reported during the Beta 3 period and applied to this release candidate. These include: * Adjustments to the costing model for hash aggregates that spill to disk. * Adjustments to the output of `EXPLAIN (BUFFERS)`. * Display the stats target of extended statistics in the output of `\d`. For a detailed list of fixes, please visit the [open items](https://wiki.postgresql.org/wiki/PostgreSQL_13_Open_Items#resolved_before_13rc1) page. Release Schedule ---------------- This is the first release candidate for PostgreSQL 13. Unless an issue is discovered that warrants a delay or to produce an additional release candidate, PostgreSQL 13 should be made generally available on September 24, 2020. For further information please see the [Beta Testing](https://www.postgresql.org/developer/beta/) page.
