Sumario:For beam operation in 2015 a number of changes and improvements are foreseen for the machine cycle. The FIDEL data must be corrected and updated. The different cycle phases will become longer and may require re-optimization. Proposals are made to improve the overall quality of the settings, to collide faster and to remove orbit spikes in the squeeze. Some issues related the collide and squeeze are briefly addressed.
