What's the difference between the new tag <#TempChangeLastHour> and the existing tag <#temptrend>? Both are described as indicating the temperature change over the last hour.

I noticed a few errors in the descriptions of some of the existing tags in the help (like <#temptrend>), but I thought I had corrected them with this build. Maybe something went wrong with the help build process.

The description of <#temptrend> in the help should be: "The average rate of change in temperature over the last three hours".
