Hi,
I like a lot of the new features in 1.6, especially the basemap (for quick sanity check on orthomosaics) and the code preview in the console.
However, it's been very frustrating having some of the parameters completely change how they work, without any sort of warning. Please keep this in mind with future API changes, for example 'mergeChunks' no longer takes chunks as input, but the chunk index, so it would be good if the function raised an Exception in 1.6 if a list of chunks was given in the first parameter (since clearly the user is thinking of 1.5 API).
The new API python manual also seems to be lacking some instructions that are critical for using the changed parameters.
