ESET continuously works to improve core functionality, improve user experience, add new features and resolve customer feedback by releasing new product versions. ESET product versioning numbers follow the format below:
|Major (feature) release||Minor version/Service release||Build number/Patch level or Security and stability hotfix||Additional differentiator (language version, security update)|
For more information about ESET product lifecycle, visit our End of Life Policy.
Major version releases introduce significant improvements, new feature additions and major changes to the product user interface or core technologies. Major new releases are indicated by the first or second number in the product version number (for example, version 6.5 could update to version 7 or 6.6).
Major version changes may also indicate changes to the operating system or software requirements. Product support or product End of Life is always linked to a major version. The changelog and known issues are posted to the corresponding download page, to the ESET Support News web page, and available by email or RSS Newsletter.
With builds and patches, ESET brings feature improvements, security and stability improvements and other updates.
Your ESET product checks for new components including product modules and Detection Engine updates many times each day. Along with our other multilayered technologies (such as DNA detection, behavioral detection and blocking and Machine learning), regular module updates help to ensure that you are protected against the latest known threats.
To verify that the latest product modules and Detection Engine have been received you can manually check for latest product updates.
You can view module changelog history from the Virus Radar Update Info page.
ESET uses Security and Stability Hotfixes to address critical issues and ensure the maximum security and stability of your ESET product. The timing of hotfixes is determined entirely by their security impact.
Security and Stability Hotfixes are distributed to all ESET business endpoint products in the same way as regular uPCU updates. Due to their nature and importance, you cannot disable Security and Stability Hotfixes, even if you disable automatic updates.
A uPCU update is used to deliver both major releases and feature updates. There are two different uPCU updates: A differential uPCU contains some patches or files (.dup), whereas a full uPCU contains all product files except modules (.fup). During the full uPCU update, the program downloads a complete copy of the latest version which is then installed over your existing ESET product.
In case of ESET solutions that consist of multiple components, (for example, ESET PROTECT), ESET may not update the product version number each time one of the components is updated.
ESET PROTECT 9.0 and ESET PROTECT Cloud 3.0 introduce automatic updates for supported ESET security products. Auto-updates are used to deliver both major releases and feature updates. The auto-updates feature downloads .dup files during the first module update check. The latest version is activated after a restart.
Auto-updates differ from uPCU updates in that Auto-updates will only update supported ESET products managed by ESET PROTECT or ESET PROTECT Cloud. uPCU updates have an automatic feature that will update managed or unmanaged ESET products.
