PROGRESS SITEFINITY LIFE CYCLE POLICY GUIDE

Updated 08/07/2024

Click here for the Table of Supported and Retired Versions Schedule

The primary objective of this document is to help customers and prospects
understand the different stages of Progress® Sitefinity® product release life
cycle and plan upgrades and/or migration of their Sitefinity software. We
strongly recommend that customers plan upgrades of their Sitefinity software on
a regular basis, preferably at least once per year, to take advantage of the
latest features, performance improvements, and security fixes. Progress
continually invests in simplifying the Sitefinity version upgrade process to
make it more reliable and streamlined. Sitefinity Cloud customers benefit from
automated software upgrades.

PRODUCT DELIVERY AND VERSIONING

Sitefinity CMS releases follow a versioning format that is based on major and
minor versions (official releases) and product updates.

Sitefinity release versions are labeled as follows:

              15.0.8200.0

where the first digit is the major release (15), the digit after the first
decimal is the minor release number (0), followed by the update build number
(8200). The last digit is the update revision number, which is used very
infrequently. When we refer to a release below, it means an official release,
such as 14.3, 15.0, etc.

Official releases contain new features, enhancements, bugfixes, ports to new
platforms, and updates to 3rd party libraries. Sitefinity has up to 3 official
releases per year.

Product updates deliver resolution of defects, critical and high security
vulnerabilities, or other product issues such as compatibility updates for
3rd-party libraries or integrations that need to be addressed outside of the
main release cycles. Occasionally, and after careful functional and
compatibility testing, we may choose to release a functional enhancement or a
new feature in a product update.

LIFE CYCLE PHASES: SUPPORT AND AVAILABILITY OF PRODUCT UPDATES

The Sitefinity Product Life Cycle consists of a series of a product release
milestones, from General Availability (GA) to the eventual Retirement. Each
Sitefinity release goes through up to three phases of product life cycle:
Active, Sunset, and Retired.

The definition of each life cycle phase below includes information about level
of support, availability of product updates, etc.

Active phase for a release begins with its General Availability (GA). Active
phase product releases are fully supported. While a release is in Active phase,
regular cumulative bugfix product updates (patches) are released to customers.
Product updates are available to all customers with a current Subscription or a
Maintenance and Support Contract. The frequency of such product updates is
generally at Progress’ discretion. Typically, bugfix product updates for the
latest Active version are released bi-weekly. The frequency of product updates
for older Active versions is reduced. 

When problems are found in an Active phase release, Progress will work with
customers towards an appropriate resolution if their licenses are covered under
a current Maintenance and Support Contract. Customers with specific customer
success packages are able to request a bugfix backport to an earlier Active
release. Progress reserves the right to recommend that a customer upgrade to a
more recent version of Progress Products if their specific problem is addressed
in that/those versions.


Sunset (Mature) phase follows the Active phase. Technical support is available
for all Sunset releases. Only critical product updates are provided during the
Sunset phase, at discretion of Progress. Progress reserves the right to
recommend that a customer upgrade to a more recent version of Progress Products
if their specific problem is addressed in that/those versions.

Note: As a rule, product updates made available during the Sunset phase do not
introduce any new features or enhancements. Further, any bugfixes that may break
functional or backward compatibility of the applicable release will only be
considered for subsequent official product releases, unless they address
critical security vulnerabilities.

Once a product version enters the Retired phase, Progress will carry no
obligation to provide product updates for this version. If problems are found
using products in the Retired phase, Progress will exercise commercially
reasonable good-faith efforts through its Product Support group to resolve
customer issues and answer customer questions for Retired versions for customers
with current Maintenance and Support contracts. This includes the possibility of
an update solely at the discretion of Progress and for a fee (based on an
assessment of the effort required by Progress). However, the availability of
knowledge and skills to diagnose and resolve issues on Retired phase products is
NOT guaranteed. Further, retired products or versions have no assurance of
security updates. For these reasons we *strongly* recommend upgrading from a
retired product version. Please contact support and/or your account manager for
guidance.

*Critical Updates/Alerts include critical security CVSS>=9 fixes and functional
fixes addressing significant breakages in functionality, whether internal or
caused by changes in 3rd party components.

**Product Updates/Alerts include High (CVSS 7-8.9) and Medium (CVSS 4- 6.9)
security fixes and selected escalated bugfixes. .

^ Best effort support only. Availability of knowledge and skills to diagnose and
resolve issues on Retired Phase products is NOT guaranteed.

Please refer to the Sitefinity Bug Fixing Policy for further details on fixes
and product updates, including security updates.

REGULAR (NON-LTS) AND LONG TERM SUPPORTED (LTS) RELEASES

Starting in 2021, the Sitefinity product line has adopted a broader Progress
life cycle policy that may designate specific official releases as Long Term
Supported (LTS) releases.

Sitefinity LTS releases are expected to have longer Active and Sunset phases
than regular releases and be supported for no less than 4 years since the
release.

Progress will make reasonable commercial efforts to support new versions of
critical third-party products that are announced by their vendors while
Sitefinity LTS releases are in Active phase. Otherwise, support for new versions
of third-party products is introduced only in new official releases.

It is possible that a 3rd party library or framework (e.g. Microsoft .NET)
version support ends earlier than our support for a specific Sitefinity version
that uses the library/framework in question. In such cases, we will recommend
upgrading your Sitefinity version to the one that uses a newer version of that
library or framework.
