8 <h1>Versions of exim</h1>
10 <p>The latest release is <b>3.14</b>. This is an incremental
11 upgrade with some new features, however old 3.0x configuration
12 files should be fully compatible. At present it appears there may
13 be some problems with this release so production environments
14 might be best left on <b>3.13</b></p>
16 <p>The previous release is <b>3.14</b>. This is an incremental
17 upgrade with some new features, however old 3.0x configuration
18 files should be fully compatible. Upgrading from previous
19 releases is worth doing, particularly since a denial-of-service
20 hole has been fixed over 3.0x and lower versions. This is a well
21 trusted version in wide use in production environments.</p>
23 <p>The previous release is <b>3.03</b>. This was a major upgrade
24 over the 2.1x series, and some features of the configuration file
25 are not backward compatible - although there is a conversion
26 utility. Earlier version <b>3.0x</b> users should upgrade,
27 although the bug fixes are relatively minor.</p>
29 <p>The last 2.x release version was <b>2.12</b>. This is a bugfix
30 release over earlier 2.1x releases. Upgrade from 2.0x releases is
33 <p>There were a number of early beta versions of exim with version
34 numbers less than <b>1.0</b>. These should now be avoided.
35 Versions earlier than <b>2.0x</b> should also be 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>
