NT7B5 Data Changes - Futures Rolloever date & IB Pacing Violation

[Aussie2]

Would seem that several data code revisions have occurred in NT7B5

1 NT7B5 now loads only 3 months of historical futures data from any contract into a chart or strategy. If more is present as shown in Historical Data Manager it is ignored. Instead NT now effectively gets data directly from earlier contracts as needed. In earlier versions I amalgamated data from consecutive contracts for back-testing. I now have to split them!
Question: Can we set the futures roll-over date? How?

2 In NT6.5 the IB adaptor included a clever algorithm to avoided the dreaded IB Pacing Violation by requesting 4 week blocks of minute data. The Pacing Violation has reappeared.
Question: Was the pacing algorithm deleted or modified in NT7B5 or has IB changed their end?

1) There are merge settings at the contract (Tools->Historical data manager->select instrument), which you may want to set to your liking (DontMerge?). Nothing has changed compared to any prior beta there.

2) Nothing has changed in regards to IB pacing violations between NT6.5 and NT7. There was no such thing like "a clever algo" to prevent this with NT6.5.
