A major update to the “KC s2M Log and Invoice” plugin

We have released several recent updates to the "KC s2M Log and Invoice" plugin, but this one introduces a major new feature: a custom reporting tool. It lets you create a snapshot of a past period and export the results as CSV. You can list members who held a selected membership level and, optionally, a selected custom capability during that period. You can also set minimum and maximum active-day values to define the time window in which a member must have held the selected level or capability. The plugin page includes a diagram explaining the calculation. The idea may sound simple, but accurately tracking this historical information is complex.
