8 <h1>Versions of exim</h1>
10 <p>The latest release is <b>4.12</b>. This is a bugfix release
11 over <b>4.10</b> and <b>4.11</b> and a recommended bug fix update
12 over earlier <b>4.0x</b> versions. The 4.x series is a major
13 upgrade over the 3.x versions which will require configuration
14 files to be rewritten (there are tools to help with this).</p>
16 <p>The latest 3.x release is <b>3.36</b>. This is the latest bug fix
17 release in the 3.3x series. They are an incremental upgrade over
18 the 3.2x series with a few new features. There is a security
19 issue (rare but exploitable) with versions previous to 3.34
20 so upgrading is <b>strongly</b> recommended.
21 Old 3.0x configuration files should be fully compatible.
22 New features are documented in the CHANGES and NewStuff files.</p>
24 <p>The previous 3.2x release is <b>3.22</b>. This is an
25 incremental upgrade with a small number of new features and some
26 bug fixes, however old 3.0x configuration files should be fully
27 compatible. New features are documented in the CHANGES and
28 NewStuff files Upgrading from previous releases is worth doing,
29 particularly since a denial-of-service hole has been fixed over
30 3.0x and lower versions.</p>
32 <p>There were a number of early beta versions of exim with version
33 numbers less than <b>1.0</b>. These should now be avoided.
34 Versions earlier than <b>2.0x</b> should also be upgraded.
35 Version 3.0x and 3.1x releases are also best upgraded.</p>
37 <p>There may be beta versions with available from the ftp sites in
38 the Testing directory. Many people are using these without
39 problems, but they are not recommended unless you are willing to
40 work with beta software.</p>
