Which version of LandTrendR should we use?

[MercedesRD]

Hello,
First of all I wanted to thank you for the wonderful tools you have developed and for sharing them with us. I have been testing the UI applications for pixel time series, so that I could tune the parameters for running the LandTrendr JavaScript module. However, I am not sure if we can use the functions from the tutorial (https://emapr.github.io/LT-GEE/api.html) with the Landsat collection 2. It seems the LandTrenr API has changed considerably between 2019 and now and I am not sure if we should use the new or the old version, especially if we are not very familiar with GEE yet.
Another question I have is related to my research question. Can we extract every year of disturbance (not just the greatest or newest) from the output of the LandTrenr API? Let´s say, to make a map of cumulative (anthropogenic) disturbance in forest plantations.
Thank you very muchs for your help, and apologies f the questions are too generic.
