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