-RELEASE NOTES:
-
-v1.1.1 -> November 2019. Bug fix in the TDD Fair Round-Robin scheduler
-v1.1.0 -> July 2019. This version adds the following implemented features:
-           * Experimental support of LTE-M
-             - Single LTE-M UE attachment, legacy-LTE UE attachment is disabled
-           * X2 interface and handover (also X2-U interface)
-             - In FDD and TDD
-           * CU/DU split (F1 interface)
-             - Tested only in FDD
-           * CDRX
-             - Tested only in FDD
-           * Experimental eMBMS support (only on UE side)
-           * Experimental multi-RRU support
-             - Tested only in TDD
-          This version has an improved code quality:
-           * Simplification of the Build System
-             - A single build includes all full-stack simulators, S1/noS1 modes and one HW platform (such as USRP, BladeRF, ...)
-           * TUN interface is now used as default for the data plane
-             - for UE, eNB-noS1 and UE-noS1
-           * Code Cleanup
-           * Better Static Code Analysis:
-             - Limited number of errors in cppcheck
-             - Important Decrease on high Impact errors in CoverityScan
-           * Better Test Coverage in Continuous Integration:
-             - TM2, CDRX, IF4.5, F1
-             - OAI UE is tested in S1 and noS1 modes with USRP board
-             - Multi-RRU TDD mode
-             - X2 Handover in FDD mode
-
-v1.0.3 -> June 2019: Bug fix for LimeSuite v19.04.0 API
-v1.0.2 -> February 2019: Full OAI support for 3.13.1 UHD
-v1.0.1 -> February 2019: Bug fix for the UE L1 simulator.
-v1.0.0 -> January 2019. This version first implements the architectural split described in doc/oai_lte_enb_func_split_arch.png picture.
-            Only FAPI, nFAPI and IF4.5 interfaces are implemented.
-            Repository tree structure prepares future integrations of features such as LTE-M, nbIOT or 5G-NR.
-            Preliminary X2 support has been implemented.
-            S1-flex has been introduced.
-            New tools: config library, telnet server, ...
-            A lot of bugfixes and a proper automated Continuous Integration process validates contributions.
-
-v0.6.1 -> Mostly bugfixes. This is the last version without NFAPI.
-v0.6 -> RRH functionality, UE greatly improved, better TDD support,
-        a lot of bugs fixed. WARNING: oaisim in PHY abstraction mode does not
-        work, you need to use v0.5.2 for that.
-v0.5.2 -> Last version with old code for oaisim (abstraction mode works)
-v0.5.1 -> Merge of bugfix-137-uplink-fixes. It includes stablity fixes for eNB
-v0.5 -> Merge of enhancement-10-harmony-lts. It includes fixes for Ubuntu 16.04 support
-v0.4 -> Merge of feature-131-new-license. It closes issue#131 and changes the license to OAI Public License V1.0
-v0.3 -> Last stable commit on develop branch before the merge of feature-131-new-license. This is the last commit with GPL License
-v0.2 -> Merge of enhancement-10-harmony to include NGFI RRH + New Interface for RF/BBU
-v0.1 -> Last stable commit on develop branch before enhancement-10-harmony
