# iRedMail release notes and upgrade tutorials

[TOC]

!!! note

    * iRedMail source code is hosted on [BitBucket](https://bitbucket.org/zhb/iredmail/src).
    * Download the [latest iRedMail stable release](../download.html).

### Why keep your iRedMail server up to date

* The latest iRedMail release brings new features, improvements, and bug fixes.
* If you plan to migrate to a new iRedMail server someday, migrating iRedMail
  to another server which runs the same release is the easiest path.

### How upgrading works

* Usually, upgrading iRedMail is just updating some config files to achieve new
  features or fix bugs, you do __NOT__ need to download the latest iRedMail and
  run the script.

* __Do NOT skip releases__. Upgrades are only supported from one release to the
  release immediately following it.

* If you're looking for upgrading a very old iRedMail server to the latest
  iRedMail release, there's an alternative solution:
  [Migrating to a new iRedMail server](./migrate.to.new.iredmail.server.html).
