Version 0.99.3 - 22th August, 2008
- Add: Correct TjMax values for 45nm Core 2 series, according to this document.
- Fix: When TjMax = 0 (undefined) "Delta to Tjunction" was not added to the temperature string.
- Fix: On the fly CPU speed didn't pick up changes when EIST was disabled (only C1E active).
