Just few moth ago we released Analytics v2x which had many new features and one of the main new features was reports accessible from frontend, for public users. Few days ago we released Analytics v3x. Why is it not 2.5 or something? What is it so important in it that we increased first version key?

The answer is "Analytics v3x is all new!". It is really a new component! Although reports transfer from backend to frontend in version 2 was done, the base of component not changed and it was very hard to make it really multi user. In v3 we refactored and now it is 100% multiuser analytics.

Also there are less report plugins now because 1 report may show more data. Previously every report plugin was associated with 1 chart type. Like pie, bars, lines, ... now user may switch charts within one report.

That required to rebuild every report. That is why for update you have to uninstall all old reports and install all over again. That was hard job to rebuild more than 150 plugins, but now it is based on the foundation that allow much more flexible and useful reporting.
