ITRS OP5 Monitor 8.x Release Notes

Compatibility and lifecycle

We support each major release of ITRS OP5 Monitor for 18 months from the release date, and we maintain the last minor release of the most recent major releases.

Release types

The version numbers consist of three digits that represent major, minor, and micro releases. For example, 8.0.6.

ITRS OP5 Monitor continuously introduces new releases, which are considered micro releases:

• Major versions provide us with an opportunity to introduce features.
• When there have been enough micro releases that changed the user experience significantly or we introduce new features, we introduce a minor version number.

• Active maintenance of a minor release implies that we are fixing issues.

See the maintenance policy below:

OP5 Monitor 8.0.8

Released: 15 October, 2019

Highlights

These are the highlights in this release:

• It has always been recommended to only restore the same version where the backup was taken from. To restore a backup from different versions of OP5 Monitor can cause serious issues. In this release, a thorough version check has been implemented for the restore of backups that prevents all restore except the exact same version.
• In the past, OP5 Monitor has filtered out SNMP results where the ifDescr field has been containing the words null or loopback. This filtering has caused issues for some customers, hence the filtering has been removed. Each customer can now decide on how to use this information.
