Some methods that possibly no longer exist?

I'm working with a project that I'm thinking was using an older version of ofxTimeline that may have had the following methods:
1. `addKeyframes`
2. `setCurrentTime`
3. `getKeyframeValue`
4. `enableDrawBPMGrid`
5. `setSnapping`

Can someone tell me if these ever existed, or if I should be using a different addon?
