9 * Add async IO support in brion::CompartmentReportMap.
10 * brion::CompartmentReportBinary::updateMapping() more robust.

18  New morphology converter tool.
19 * New null compartment report for benchmarks.
20 * New spike converter tool.
21 * Optimized function Circuit::get for large circuits (cut down the loading time
22  of the 3.1 M neuron circuit by 6.5 seconds in a Core i7-4930K @ 3.40GHz).
23 * Replace use of iostreams by lunchbox::MemoryMap.

33 * New constructor for brion::CompartmentReport accepting an URI and the desired
34  access mode deprecates the old read and write constructors.
35 * New compartment report based on key-value stores supported by
36  Lunchbox::PersistentMap.
37 * Spike loading has been optimized (in a 12-core GPU the expected
