This notification provides details regarding the transition to a Calendar Versioning (CalVer) schema for Trellix Endpoint Security (ENS).
Version schema change
Starting in May 2026, ENS for Windows, MacOS, and Linux will move to the CalVer schema. The new version format will be [YY.MM].Patch.Build (e.g., 26.5.0.12436).
The transition to CalVer offers the benefit of a clear, predictable release schedule where version numbers directly correspond to release dates.
Note: Version 26.5 is the first release planned under this new schema, scheduled for May 2026.
