What aspect of the old rotation plan has changed according to the new proposal?

The aspect of the old rotation plan that has changed according to the new proposal is that it allows for flexibility. This means that the new proposal is not rigidly bound by previous restrictions such as mandatory locations or rigid scheduling. Flexibility can accommodate a variety of needs and circumstances, providing the opportunity for conventions to be held in diverse locations or adjusting the timing of events based on current situations or stakeholder inputs.

For example, rather than adhering to a strict rotation where specific sites are predetermined and repeated in a set order, the new approach might permit alternate locations that better reflect the needs of participants or the logistics of each convention. This adaptability can lead to increased attendance, engagement, and ultimately a more successful event overall.
