Differences between Notes/Domino Maintenance Releases, Feature Packs, Fix Packs & Upgrade Packs



This document provides an explanation of the differences between Lotus Notes and Domino Maintenance Releases, Feature Packs, Fix Packs and Upgrade Packs.


What is a Maintenance Release?

Maintenance Releases (MR) are scheduled updates containing a large number of Server and Client fixes. They contain 500 to as many as 2,000 fixes. Maintenance Releases are shipped more frequently (1-2 times a year) shortly after a feature release ships, and less frequently as a release matures. Maintenance Releases undergo extensive testing which includes: bug fix verification, regression testing, interoperability testing with products that work with Notes/Domino, and are deployed in a production environment.

What is a Feature Pack (formerly Fix Packs)?

IMPORTANT NOTE: Beginning with 9.0.1 FP8, Fix Packs have been renamed to Feature Packs (FP). For related information, see the following blog post: IBM Notes and Domino Product Update from Connect 2017

Feature Packs (formerly Fix Packs) have a high focus on addressing high-impacting defects as well as delivering new functionality. The Feature Pack model allows for a more modern continuous delivery of features like database improvements and Java runtime updates.

Fix Packs are released periodically between Maintenance Releases to provide a greater level of stability for customer environments. They contain a small number of safe fixes that help to address the issues the broader customer base is or is likely to experience. The SPRs selected to be fixed focus on bad regressions, crashes, hangs, security issues, data loss issues, and critical functional bugs. To ensure quality, the triage criteria for inclusion in a fix pack targets safe fixes that have been deployed in a production environment, doesn't impact translation, and doesn't contain new features.  By delivering a limited number of fixes in a smaller package, customers can deploy with less testing and less risk then a bigger Maintenance Release.  Customers can also spend the time needed to validate a Maintenance Release before deploying, while utilizing Fix Packs in the interim to address the bulk of the more pervasive issues. Fix Packs undergo testing which includes: bug fix verification, targeted regression testing, interoperability testing with products that work with Notes/Domino, and are deployed in a production environment.
What is an Upgrade Pack?

An Upgrade Pack is an optional update for a specific new feature. NOTE: Prior to the 8.5.3 Maintenance Release, Upgrade Packs were referred to as Interim Feature Releases (IFR).
Comparison Table

Maintenance Release
Feature/Fix Pack
Upgrade Pack
Pre-ship Testing and Validation Extensive Extensive Extensive
Number of fixes 500+ Typically 50+ Feature release only
Types of fixes Mix of high & low impact High impact Feature release only
Client and/or Server Client & Server Client & Server starting in 8.0.2 FP1 Server or Client
Availability 1-2 times per year As needed As needed
Installation Full Notes installation Bug fixes applied to base Modification to full install
Platforms and Languages Specific installer for each language All; single install functions on all language versions All; single install functions on all language versions
Note about Mass Deployment:
  • To mass deploy an Interim Fix (hotfix) or Fix Pack for the Notes client, your options are to use the Notes/Domino Smart Upgrade feature and/or the Smart Upgrade RunAs (SuRunAs) utility.
  • While the Domino Update Site feature can be used to deploy plug-in updates, it cannot be used to deploy Notes client code fixes.

General Q&A

If there is both a client and server Fix Pack, do you have to install both?
Just like any prior release, where different client and server versions interoperate, the same is true with Fix Packs. They do not need to be running the same version.

Can you install fixes for Notes 8.x Standard Configuration clients on Notes 8.x Basic Configuration clients (or vice versa).
No. Be sure to download and apply the fix type specific to the configuration (mode) of Notes 8.x you are running.

Is it possible to combine a Notes maintenance release (e.g. 8.5.1) with a Fix Pack (e.g. 8.5.1 FP1) into a single install kit? I am interested in reducing the size of the installation kit and not have to install two discreet packages.
While it is not possible to combine the kits into a single MSI package, customers can execute the two install packages serially and silently, in essence having a single install package that executes two discreet installs underneath and silently (if desired). In the future, we hope to reduce the size of patches.

How do client MU I ( Multilingual User Interface) packs work with client Fix Packs? MUI packs for Notes 8.0.2.x and 8.5.x should be installed before fixes to avoid install issues. See technote #1404436 for details. MUIs produced in 8.5.1 and above will address this issue.

How are Fix Packs announced?
The status and subsequent announcement of Fix Packs can be found in the Notes/Domino Fix List on developerWorks.

Where can you find Fix Packs? Are CDs available?
Fix Packs are available for download at Fix Central. CDs are not made available. You can find direct download links to Fix Packs in the following technotes:
