## Appendix E. Release Notes

The release notes contain the significant changes in each Postgres Pro 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.

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.

## E.1. Postgres Pro Enterprise 10.5.3

Release date: 2018-10-11

### E.1.1. Overview

This release is based on Postgres Pro Standard 10.5.3 and Postgres Pro Enterprise 10.5.2. All changes inherited from Postgres Pro Standard 10.5.3 are listed in Postgres Pro Standard 10.5.3 Release Notes. As compared with Postgres Pro Enterprise 10.5.2, this version also provides the following change:

- `pgbadger` now supports the extended log format of `Postgres Pro Enterprise`. Its package got renamed to `pgpro-pgbadger`.

### E.1.2. Migration to Version 10.5.3

If you are upgrading from a Postgres Pro Enterprise version based on the same PostgreSQL major release, it is enough to install the new version into your current installation directory.

### Important

When upgrading from versions 10.3.3 or lower, you must execute the `REINDEX` command for GiST and SP-GiST indexes, as well as indexes that use `mchar` or `mvarchar` types.

To migrate from PostgreSQL, Postgres Pro Standard, or Postgres Pro Enterprise versions based on any previous PostgreSQL major release, see the instructions in Postgres Pro Enterprise 10.1.1 Release Notes. If you are opting for a dump/restore, make sure to use the `--add-collprovider` option to correctly choose the collation provider for the migrated database.
