## E.366. Release 7.4.5

Release date: 2004-08-18

This release contains one serious bug fix over 7.4.4. For information about new features in the 7.4 major release, see Section E.371.

### E.366.1. Migration to Version 7.4.5

A dump/restore is not required for those running 7.4.X.

### E.366.2. Changes

- Repair possible crash during concurrent B-tree index insertions

  This patch fixes a rare case in which concurrent insertions into a B-tree index could result in a server panic. No permanent damage would result, but it's still worth a re-release. The bug does not exist in pre-7.4 releases.
