Supported Releases

This section sets out Isode's policy on support of releases.

Types of Release

Isode makes two kinds of release:

Major Release (e.g. Release R15). Major releases have significant changes in one or more of the Isode products, relative to the previous major release. Upgrades to new major releases may need specific upgrade actions, such as running tools to upgrade database format.
Minor Release (e.g. Release R15.1). New minor releases contain changes to the functionality of the product. Upgrading to this release from another release within the same major release (e.g., R15.0 to R15.1) should be straightforward.

Releases have one or more versions, and the version is specified after the release number (e.g. Release R15.2v1 is version 1). Update versions contain fixes for defects made since previous versions of the Minor or Major release. Upgrading to a new version of a release (e.g., R15.2v0 to R15.2v1) should be trivial.

The basic version number of a specific release version has three fields, corresponding to the major, minor and version numbers, e.g. R15.0v4.

Fully Supported Releases

Isode provides full support for Major and Minor releases of Isode's server products, management tools and APIs for five years from the date of release. The exceptions to this rule are the R14.5 series of releases which were supported for 6 months from release date only (R14.5 was a specialised M-Link only release, changes to which were rolled into R14.6) and the Swiften XMPP Client Library (see below).

Release	Release Date	End of Full Support
R14.3	August 2008	August 2013
R14.4	April 2009	April 2014
R14.6	April 2010	April 2015
R15.0	June 2011	June 2016
R15.1	November 2011	November 2016
R15.2	October 2012	October 2017

A guide to specific supported releases is available.

Isode product licenses are platform and release independent, and support includes maintenance so that customers can always upgrade to the latest release. Isode will only provide support for a release deployed 12 months or more after its release date on prior agreement for good operational reasons such as the need to add additional nodes to an existing deployment. The goals of this policy are to:

Provide certainty to users and long term support to stable deployments.
Ensure that new deployments will generally use the latest Isode release.
Provide update releases only on platforms that customers are using.

Swiften XMPP Client Library

Isode currently provides support for version 2.0 of the Swiften XMPP Client Library.

Support of Releases not on Full Support

Isode will provide a reduced level of support to customers with older releases that are not on full support. The main caveat is that Isode will not, in normal circumstances, make any new updates of these older products in order to fix bugs. We will be happy to advise on configuration issues and workarounds to problems, in line with our normal support obligations and depending on the age of the release.
