I came across this KB this morning and thought it might be a useful one to share:
What are BlackBerry Enterprise Server software maintenance releases
Doc ID : KB14047
Environment
- BlackBerry® Enterprise Server software versions 4.0 and 4.1
Overview
The two types of maintenance releases (MRs) that you can install are hotfixes and rollups.
Hotfix
A hotfix contains fixes for identified defects or potential security vulnerabilities in the BlackBerry Enterprise Server. As a result of the often urgent and reactive nature of a hotfix, a release schedule is not followed. A hotfix can be specific to customers or BlackBerry Enterprise Server software versions. Before you download and install a hotfix, it is recommended that you read the corresponding release notes to determine whether it applies to your environment and addresses an issue that is important to your organization’s BlackBerry Enterprise Server software installation.
Rollup
A rollup contains a small set of fixes. It can include the same types of fixes as hotfixes, but it is intended to release important fixes on a schedule. A rollup can be expected to be released approximately six weeks after the previous maintenance release is posted.
For example, an organization that is using BlackBerry Enterprise Server software version 4.1 Service Pack 4 (4.1.4) can install any of the following posted maintenance releases:
- BlackBerry Enterprise Server software version 4.1.4 MR1 (Rollup)
- BlackBerry Enterprise Server software version 4.1.4 MR2 (Hotfix)
- BlackBerry Enterprise Server software version 4.1.4 MR3 (Rollup)
- BlackBerry Enterprise Server software version 4.1.4 MR4 (Rollup)
In this example, each maintenance release (MR1 through MR4) contains all of the fixes from previous maintenance releases. MR2, which is a hotfix, contains new fixes and fixes for all issues addressed in MR1, which is a rollup.
