## E.3. Release 7.4.5

### Release date

2004-08-18

This release contains one serious bug fix over 7.4.4.

### E.3.1. Migration to version 7.4.5

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

### E.3.2. Changes

- Repair possible crash during concurrent btree index insertions

  This patch fixes a rare case in which concurrent insertions into a btree 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.
