Important Change
Starting from this release, VirtualMemoryStat.Used on Linux is now calculated based on MemAvailable in meminfo. This may cause a difference of approximately 6–10% compared to the previous calculation.
To address this, we have introduced an opt-out mechanism. You can disable the new calculation by setting the context key WillBeDeletedOptOutMemAvailableCalc to true. Please note that this option is undocumented and will be removed in six months (Feb. 2026).
For more details, see #1873 and #1882.
