# E.84. Release 8.0.13

> Release date: 2007-04-23

This release contains a variety of fixes from 8.0.12, including a security fix. For information about new features in the 8.0 major release, see Section E.97.

## E.84.1. Migration to Version 8.0.13

A dump/restore is not required for those running 8.0.X. However, if you are upgrading from a version earlier than 8.0.6, see the release notes for 8.0.6.

## E.84.2. Changes

- Support explicit placement of the temporary-table schema within `search_path`, and disable searching it for functions and operators (Tom)

  This is needed to allow a security-definer function to set a truly secure value of `search_path`. Without it, an unprivileged SQL user can use temporary objects to execute code with the privileges of the security-definer function (CVE-2007-2138). See `CREATE FUNCTION` for more information.

- `/contrib/tsearch2` crash fixes (Teodor)

- Fix potential-data-corruption bug in how `VACUUM FULL` handles `UPDATE` chains (Tom, Pavan Deolasee)

- Fix PANIC during enlargement of a hash index (bug introduced in 8.0.10) (Tom)

- Fix POSIX-style timezone specs to follow new USA DST rules (Tom)
