FSE software: releases, hot fixes, and system maintenance releases
FSE software is distributed in form of FSE releases, FSE hot fixes, and FSE system maintenance releases. FSE
hot fixes and FSE system maintenance releases are meant for fixing problems that emerged after the new
FSE version was released. The next sections describe the differences between them and provide
recommendations for their usage.
FSE releases
Every new FSE release introduces new functionality. An FSE release with a new minor version number
introduces functional improvements and enhancements, while an FSE release with a new major version
number introduces major functionality changes and/or architectural redesigns. The FSE release installation
process uses the native operating system installation method, that is RPM packages.
FSE hot fixes
An FSE hot fix is an update to the FSE software that solves one or more problems that were reported by FSE
customers or FSE support engineers. It is based either on an FSE release or an FSE system maintenance
release. Each new FSE hot fix solves one or more newly reported problems.
An FSE hot fix includes all packages and files that are included into FSE release software. Therefore, a hot
fix replaces the entire FSE software fileset. It can be either used for a first-time FSE installation, or an
existing FSE installation can be upgraded with it.
FSE hot fixes are cumulative. This means that an FSE hot fix with a particular consecutive number contains
all functional changes of the hot fixes that are labelled with smaller consecutive numbers, and therefore
supersedes all of them.
NOTE: FSE hot fixes are designed to solve the problems that emerge between release dates of FSE
releases and/or FSE system maintenance releases. If an FSE hot fix and a particular SMR containing this
hot fix are available, you are recommended to use the SMR rather than the hot fix.
FSE system maintenance releases
An FSE system maintenance release (SMR) includes functional changes and improvements of several FSE
hot fixes. It can be treated as an FSE release, improved with all the FSE hot fixes that were included into it.
Usually, it includes all the hot fixes that have been released and confirmed by the time the system
maintenance release was prepared, which are complemented with additional, SMR-only enhancements.
An FSE system maintenance release includes all packages and files that are included into FSE release
software. Therefore, an SMR replaces the entire FSE software fileset. It can be either used for a first-time
FSE installation, or an existing FSE installation can be upgraded with it.
FSE system maintenance releases are cumulative. This means that an SMR with a particular consecutive
number contains all functional changes of the SMRs that are labelled with smaller consecutive numbers,
and therefore supersedes all of them.
