Guidance for Selecting LoadMaster Releases

When downloading a LoadMaster installation or upgrade image for deployment, customers need to understand the content of each release stream so they can make an informed decision. The choice you make will likely depend on the relative stability and content of each release stream.

The following are our recommendations for production use based on how we label our new releases, in order of preference.

LTSF
Long Term Support Feature Release

This is the recommended release for production deployments for all customers, unless a specific feature or fix in the GA release is required.

LMOS 7.2.54 is the LTSF release branch, with the current release being 7.2.54.4. It contains all features and bug fixes from earlier releases, along with critical fixes, security fixes, and selected features from GA releases of LMOS 7.2.55 and above.

GA
General Availability Release

This is the recommended release for production deployments for customers that require new features and fixes not present in the LTSF release.

LMOS 7.2.57.0 is the current GA release. It contains all features and bug fixes from earlier releases, including of course the LTSF and LTS branches.

LTS
Long Term Support Release

This is the "gateway" release for production deployments for customers running legacy versions of LMOS prior to 7.2.48.0 that are no longer supported. Customers running legacy releases are encouraged to upgrade to the LTS or LTSF releases.

New customers should install the LTSF release, unless there is a specific reason to install the LTS.

LMOS 7.2.48 is the LTS release branch, with the current release being 7.2.48.7. This branch is updated with critical bug fixes and security fixes from later LMOS releases on a priority basis. New features from GA releases are not added to the LTS release.

EA
Early Access Release

Early access releases are made available on as as-needed basis to give customers the opportunity to try out new features before they are included in a production release and are not recommended for production use.

There is no EA release of LMOS currently available.

 

LMOS Release Feature Contents

In addition to the above, the following sections list the major features in each of the releases described above to help you decide which release is appropriate for your deployment.
