Caveats

Look here for information on embedding the latest beta/release.

In order to achieve effective frame recycling, tooltips must be released. Holding a tooltip leads to the creation of a full set of frames for every AddOn which does not follow this practice. Moreover, releasing a tooltip has a very little overhead compared to its benefits.

Known issues

• Alignment may be altered when using :SetScale after filling the tooltip.
