-### Included Fixes: ###
+ *  [OAI License Model](http://www.openairinterface.org/?page_id=101)
-- Ease of use of gprof and address sanitizer for debugging purposes
+ *  [OAI License v1.1 on our website](http://www.openairinterface.org/?page_id=698)
-- Updated json files to allow for GDB, real-time debugging capabilities
-- Updated logging features to minimally log only key connection milestones. This imroves scalability of multiple UEs.
-- Updated logging to include time stamp for timing analysis
-- Updated memory allocation procedures to correct size requirements
-- Added debugging features to handle signal terminations
-- nfapi.c pullarray8 fix invalid pointer math
-- Overlapping destination and source memory in memcpy, so updated to memmove to check for this bug
-- Advanced error checking mechanisms in critical pack and unpack functions
-- Created option for CPU assignment to UE to improve scalability
-- Added EPC integration to allow multiple individual UE entities to each have their USIM information parced by the executables
-- Updated random value seeds to minimize probability of error in generation of random values
-- Enables capability round robin scheduler if desired
-- Enables capability real time scheduler if desired
-- Added new standalone functions to the UE phy-layer (phy_stub_ue.c) to incorporate individual UE entities
-- Updated sending and packing functions in UE (lte_ue.c) to incorporate new standalone changes
-- Incorporated semaphores to control timing of incoming downlink packets
-- Implemented new queuing system to handle message exchange from UE to eNB and vice versa
-- Updated global value in nFAPI for size of subframe
-- Updated global value to increase scalability in system

 This simulator connects a eNodeB  and UEs through a nfapi interface, short-cutting the L1 layer. The objective of this simulator is to allow multi UEs simulation, with a large number of UEs (ideally up to 255 ) .Here to ease the platform setup, UEs are simulated via a single `lte-uesoftmodem` instance. Today the CI tests just with one UE and architecture has to be reviewed to allow a number of UE above about 16. This work is on-going.
